SEMIANNUAL REPORT

ETERNAL PRINCIPLES

     Markets change,  but the principles of successful  investing do not. During
the past few years, radical upheaval in the stock market has displayed the power
of this simple truth to dramatic effect.

     In the late 1990s,  stocks  experienced one of the greatest bull markets in
financial  history.  Then, in March 2000,  the longest  downturn since the Great
Depression began.

     In both  bull and bear  markets,  however,  the  principles  of  successful
investing  are  identical:  balance,  diversification,  and  attention to costs.
Balance among stock, bond, and money market funds allows you to pursue long-term
growth while moderating your risk.  Diversification  limits your exposure to the
disasters  that can befall any one security or sector.  Attention to costs means
you keep a larger share of any rewards produced by your investments.

     These principles are timeless. In fact, they're the basis of our very first
mutual  fund--Vanguard(R)  Wellington(TM) Fund, a balanced portfolio established
in 1929. Over time, balance, diversification, and attention to costs have proven
to be the master keys to investment success.

SUMMARY

*    During the first half of its 2003 fiscal year,  Vanguard STAR Fund returned
     5.4%, outpacing its comparative measures.

*    Both  stocks  and bonds  made  solid  gains.  International  stocks  lagged
     domestic equities, but were in the black.

*    Corporate bonds and stocks of smaller companies  generally  performed well,
     bolstering STAR's performance.

LETTER FROM THE CHAIRMAN                              [PHOTO OF JOHN J. BRENNAN]
                                                                 JOHN J. BRENNAN
Fellow Shareholder,

Both  stocks and bonds made solid  gains  during the six months  ended April 30,
2003. Vanguard STAR Fund posted a return of 5.4%, which was higher than those of
its comparative measures.
     The table below  compares  the fund's  total  return  (capital  change plus
reinvested  distributions) with those of its two main benchmarks: a composite of
mutual  fund groups  weighted  to reflect  STAR's  investment  guidelines  and a
similarly  weighted  composite of unmanaged market indexes.  As of this calendar
year,  each  of  our  composite   benchmarks  includes  an  international  stock
component,  and the money market  component has been  replaced  with  short-term
bonds. These changes better reflect the makeup of the STAR Fund, which has owned
shares of  international  stock  funds  since  August 2001 and uses a bond fund,
rather than a money market fund, for its short-term investments.

STOCKS OPENED AND CLOSED STRONGLY
During the six months ended April 30, 2003,  the overall U.S.  stock market,  as
measured by the Wilshire 5000 Total Market Index,  returned  5.0%, a performance
reflecting vigorous rallies at the beginning and end of the period. Inside these
bookends,   however,   stock  prices  drifted   lower,   depressed  by  investor
apprehension  about  geopolitical  tensions and generally  glum  economic  news.
Although the U.S. military  campaign in Iraq was brief and successful,  economic
uncertainty  remained.   Consumer  spending  was  strong,  but  the  job  market
deteriorated,  and the red-hot residential real estate market began to cool. The
broad economy registered anemic growth.

                                                                               1

*Annualized.

     Small stocks,  as represented by the Russell 2000 Index,  performed  better
than the large stocks in the Russell 1000 Index, while growth stocks (those that
are expected to produce  rapid  earnings  growth) and value  stocks  (those that
generally trade at below-market valuations) produced similar returns.
     Overseas,  Asian stock markets were hit  especially  hard,  but as a group,
international stocks produced a modest positive return for U.S.-based investors.

BONDS DEFIED EXPECTATIONS
Bonds generated  surprisingly strong results, with the Lehman Brothers Aggregate
Bond Index--a broad measure of the taxable bond market--  returning  4.3%.  Bond
yields  began the fiscal  half-year at their  lowest  levels in 40 years,  which
would  generally  portend  unimpressive  returns.  But the bond  market  rallied
further,  in part because of a strong rebound in hard-hit corporate bonds. Long-
and  intermediate-term  interest rates fell modestly during the period,  and the
yield  of the  3-month  U.S.  Treasury  bill--a  fair  proxy  for  money  market
yields--declined 34 basis points (0.34 percentage point) to 1.11%.

ALL HOLDINGS ROSE FOR STAR
Vanguard STAR Fund's 5.4% return was almost a percentage  point higher than that
of its benchmark composite index and even farther above the composite peer-group
average.  STAR also  outpaced  both the broad stock and bond markets for the six
months--an unusual, and pleasant, turn of events for a balanced fund.
     As you know, the STAR Fund is a "fund of funds," through which you are able
to  invest  in a wide  range of  Vanguard  funds at low cost and  without  being
subject to their minimum investment requirements.  The table opposite shows each
fund's weighting in STAR and six-month return as of April 30.

All 11  funds  posted  positive  returns.  Their  gains  ranged  from  0.2%  for
Vanguard(R) International Value Fund, reflecting the relatively poor performance
of overseas markets, to a stellar 9.8% for Vanguard(R) Long-Term Corporate Fund.
The latter  enjoyed the double boon of falling  interest  rates and a rebound in
investors'  desire for  corporate  bonds.  (A decline in interest  rates,  which
causes the prices of existing bonds to rise,  typically  gives the biggest boost
to longer-term bonds.  Conversely,  these bonds' prices often fall farthest when
interest rates are rising.)

- --------------------------------------------------------------------------------
*As of April 30, 2003.

     Government and mortgage-backed securities--among the biggest winners during
the previous  three  years--lagged  corporate  bonds during the past six months,
resulting in Vanguard(R) GNMA Fund's 2.7% return.  Among the underlying domestic
equity funds,  returns ranged from 2.2% for Vanguard(R) U.S. Growth Fund to 8.7%
for Vanguard(R) Windsor(TM) Fund. Large-cap growth stocks--the focus of the U.S.
Growth  Fund--generally posted the lowest returns among market segments. For the
Windsor Fund and Vanguard(R)  PRIMECAP Fund, the investment  advisers'  somewhat
outsized and contrarian  stock  selections  paid off  handsomely  during the six
months.  Indeed,  9 of STAR's 11 underlying  funds easily outpaced their average
mutual fund peers.  (The two exceptions were the U.S.  Growth and  International
Value Funds, which slightly lagged the average returns of their peer groups.)
     STAR has no expenses of it's own, but  shareholders  incur a portion of the
expenses of the underlying  funds.  STAR's effective  expense ratio  (annualized
operating  costs as a  percentage  of average net assets) of 0.44% was far lower
than the 1.36% charged by it's average peer.

                                                                               3


THE BEST SOLUTION TO UNCERTAINTY MAY BE THE SIMPLEST ONE
Now that we have seen a break in the  longest  bear  market in stocks  since the
Great Depression, many investors may be asking themselves, "Is the worst finally
over?"  Neither we nor anyone else can answer  that.  We can say that stocks are
more  reasonably  priced than they were three years ago,  and--with  higher bond
prices and lower  yields--fixed  income securities are riskier than they used to
be. But no one can foretell what the markets will do in the short term.
     For this  reason,  we believe it is prudent for most people to stick with a
balanced  investment  plan,  diversified  across  asset  classes in  proportions
appropriate for their situation,  goals, time horizon,  and risk tolerance.  The
STAR Fund provides a convenient and low-cost means to pursue such a plan.
     We thank you for your continued trust and confidence.


Sincerely,

/S/ JOHN J. BRENNAN

GLOSSARY OF INVESTMENT TERMS

AVERAGE WEIGHTED EXPENSE RATIO.  Funds that invest in other Vanguard funds incur
no  direct  expenses,  but  do  bear  proportionate  shares  of  the  operating,
administrative,  and  advisory  expenses of the  underlying  funds.  The average
weighted  expense  ratio is the  average of these  expense  ratios,  weighted in
proportion to the amount of the fund invested in each underlying fund.
- --------------------------------------------------------------------------------
BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation  to the ups and downs of the  overall  market  (or  appropriate  market
index).  The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20  typically  would have seen its share price rise or fall by 12% when the
overall market rose or fell by 10%. However, a fund's beta should be reviewed in
conjunction with its R-squared (see definition  below). The lower the R-squared,
the less correlation  there is between the fund and the benchmark,  and the less
reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
EXPENSE  RATIO.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------
R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns from the overall market (or its benchmark  index). If a fund's total
returns  were  precisely  synchronized  with the overall  market's  return,  its
R-squared  would be 1.00.  If the fund's  returns  bore no  relationship  to the
market's returns, its R-squared would be 0.
- --------------------------------------------------------------------------------
YIELD.  A snapshot of a fund's  income from interest and  dividends.  The yield,
expressed  as a  percentage  of the fund's net asset  value,  is based on income
earned over the past 30 days and is  annualized,  or  projected  forward for the
coming year.

PERFORMANCE SUMMARY                                         As of April 30, 2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

FINANCIAL STATEMENTS                                  April 30, 2003 (unaudited)

STATEMENT OF NET ASSETS
This Statement  provides a detailed list of the fund's  investments in shares of
each Vanguard fund,  along with the value of each  investment on the last day of
the reporting period.  Other assets are added to, and liabilities are subtracted
from,  the value of Total  Investments  to  calculate  the  fund's  Net  Assets.
Finally,  Net Assets are divided by the outstanding shares of the fund to arrive
at its share price, or Net Asset Value (NAV) Per Share.
     At the end of the Statement of Net Assets, you will find a table displaying
the  composition  of the fund's net assets.  Because all income and any realized
gains must be  distributed  to  shareholders  each year,  the bulk of net assets
consists of Paid-in Capital (money invested by shareholders).  The amounts shown
for  Undistributed  Net  Investment  Income and  Accumulated  Net Realized Gains
usually   approximate   the  sums  the  fund  had  available  to  distribute  to
shareholders as income  dividends or capital gains as of the statement date. Any
Accumulated Net Realized Losses, and any cumulative excess of distributions over
net income or net realized gains, will appear as negative  balances.  Unrealized
Appreciation  (Depreciation)  is the difference  between the market value of the
fund's investments and their cost, and reflects the gains (losses) that would be
realized if the fund were to sell all of its investments at their statement-date
values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the fund's total net assets changed during the two most
recent reporting periods. The Operations section summarizes information detailed
in  the  Statement  of  Operations.   The  amounts  shown  as  Distributions  to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the amount shareholders invested in the
fund,  either by purchasing shares or by reinvesting  distributions,  as well as
the amounts redeemed.  The  corresponding  numbers of Shares Issued and Redeemed
are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table  summarizes  the  fund's  investment  results  and  distributions  to
shareholders on a per-share  basis. The table also presents the Total Return and
shows net  investment  income and expenses as percentages of average net assets.
The expense ratio is zero because the fund pays no direct  expenses;  the fund's
share of the expenses of the other funds in which it invests  reduces the income
received from them. The data in the table will help you assess:  the variability
of the  fund's  net income and total  returns  from year to year;  the  relative
contributions  of net income and capital gains to the fund's total  return;  the
extent to which the fund tends to distribute  capital gains;  and the portion of
capital  gain  distributions  representing  the  "pass-through"  of capital gain
distributions  received  from  other  Vanguard  funds.  The table also shows the
Portfolio Turnover Rate, a measure of trading activity.  A turnover rate of 100%
means that the average security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard STAR Fund is registered under the Investment  Company Act of 1940 as an
open-end  investment  company,  or mutual  fund.  The fund  follows  a  balanced
investment  strategy by investing in selected  Vanguard funds.  The fund invests
60% to 70% of its net assets in stock funds (predominantly  large-capitalization
value U.S. stock funds),  20% to 30% in  intermediate-  to long-term bond funds,
and 10% to 20% in a short-term bond fund.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The fund consistently follows such
policies in preparing its financial statements.

     1.  Valuation:  Investments  are  valued  at the net  asset  value  of each
Vanguard  fund  determined  as of the  close  of the  New  York  Stock  Exchange
(generally  4:00  p.m.  Eastern  time) on the  valuation  date.  Temporary  cash
investments are valued at cost, which approximates market value.

     2.  Repurchase  Agreements:  The fund,  along  with  other  members  of The
Vanguard Group,  transfers  uninvested cash balances into a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.

     3.  Federal  Income  Taxes:  The fund  intends to  continue to qualify as a
regulated   investment  company  and  distribute  all  of  its  taxable  income.
Accordingly,  no provision for federal income taxes is required in the financial
statements.

     4.  Distributions:  Distributions  to  shareholders  are  recorded  on  the
ex-dividend date.

     5. Other:  Income and capital gain  distributions  received are recorded on
the  ex-dividend  date.  Security  transactions  are  accounted  for on the date
securities are bought or sold.  Costs used to determine  realized gains (losses)
on the sale of investment securities are those of the specific securities sold.

B. Under a special service  agreement,  The Vanguard Group  furnishes  corporate
management,  administrative,  marketing,  and distribution services to the fund.
The special service  agreement  provides that Vanguard will reimburse the fund's
expenses to the extent of savings in administrative and marketing costs realized
by Vanguard in the operation of the fund. Accordingly,  all expenses incurred by
the fund  during  the six  months  ended  April 30,  2003,  were  reimbursed  by
Vanguard.  The fund's  trustees and officers are also  directors and officers of
Vanguard and the funds in which the fund invests.

C.  Distributions  are  determined  on a tax  basis  and  may  differ  from  net
investment income and realized capital gains for financial  reporting  purposes.
Differences   may  be  permanent  or  temporary.   Permanent   differences   are
reclassified among capital accounts in the financial statements to reflect their
tax  character.  Temporary  differences  arise  when  certain  items of  income,
expense,  gain,  or loss are  recognized  in  different  periods  for  financial
statement and tax purposes;  these  differences will reverse at some time in the
future.  Differences  in  classification  may also result from the  treatment of
short-term gains as ordinary income for tax purposes.

     The fund's  tax-basis  capital gains and losses are determined  only at the
end of each fiscal year.  For tax  purposes,  at October 31, 2002,  the fund had
available  realized  losses of  $9,526,000  to offset  future net capital  gains
through October 31, 2010. The fund will use these capital losses to

14


offset net  taxable  capital  gains,  if any,  realized  during the year  ending
October 31, 2003;  should the fund realize net capital  losses for the year, the
losses will be added to the loss carryforward balances above.

     At April 30, 2003, net unrealized appreciation of investment securities for
tax purposes was $399,001,000, consisting of unrealized gains of $723,080,000 on
securities  that had risen in value since their  purchase  and  $324,079,000  in
unrealized losses on securities that had fallen in value since their purchase.

D. During the six months ended April 30, 2003, the fund  purchased  $880,086,000
of investment  securities and sold  $905,508,000 of investment  securities other
than temporary cash investments.

                                                                              15

THE PEOPLE WHO GOVERN YOUR FUND

The  trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder,  you are a part owner of
the fund.  Your  fund  trustees  also  serve on the  board of  directors  of The
Vanguard  Group,  Inc.,  which is owned by the  Vanguard(R)  funds and  provides
services to them on an at-cost basis.

     A majority of Vanguard's board members are  independent,  meaning that they
have no  affiliation  with  Vanguard or the funds they  oversee,  apart from the
investments they have made as private individuals. Our independent board members
bring  distinguished  backgrounds in business,  academia,  and public service to
their task of working  with  Vanguard  officers to  establish  the  policies and
oversee the activities of the funds.

     Among board members' responsibilities are selecting investment advisers for
the  funds;  monitoring  fund  operations,  performance,  and  costs;  reviewing
contracts;  nominating  and  selecting  new  trustees/directors;   and  electing
Vanguard  officers.  The dates in  parentheses  below show when each trustee was
initially elected.

ETERNAL PRINCIPLES

     Markets change,  but the principles of successful  investing do not. During
the past few years, radical upheaval in the stock market has displayed the power
of this simple truth to dramatic effect.

     In the late 1990s,  stocks  experienced one of the greatest bull markets in
financial  history.  Then, in March 2000,  the longest  downturn since the Great
Depression began.

     In both  bull and bear  markets,  however,  the  principles  of  successful
investing  are  identical:  balance,  diversification,  and  attention to costs.
Balance among stock, bond, and money market funds allows you to pursue long-term
growth while moderating your risk.  Diversification  limits your exposure to the
disasters  that can befall any one security or sector.  Attention to costs means
you keep a larger share of any rewards produced by your investments.

     These principles are timeless. In fact, they're the basis of our very first
mutual  fund--Vanguard(R)  Wellington(TM) Fund, a balanced portfolio established
in 1929. Over time, balance, diversification, and attention to costs have proven
to be the master keys to investment success.
- --------------------------------------------------------------------------------
SUMMARY

*    The Vanguard  LifeStrategy Funds posted solid six-month returns, with three
     funds gaining 4.7% and the fourth, 4.8%.

*    Despite extreme  volatility,  the broad U.S. stock market slightly outpaced
     the broad U.S. bond market in the half-year ended April 30, 2003.

*    Thanks to a relatively large commitment to stocks,  each  LifeStrategy Fund
     outperformed its benchmark composite index.

LETTER FROM THE CHAIRMAN

FELLOW SHAREHOLDER,

Both  stocks and bonds made solid  gains  during the six months  ended April 30,
2003, with stocks winding up slightly ahead in the U.S. markets. The results for
the four  Vanguard  LifeStrategy  Funds were  strikingly  close to one  another:
Despite  their very  different  allocations  to stocks and  bonds,  three  funds
returned  4.7% and the fourth,  4.8%.  This  similarity  resulted  from both the
near-parity of overall stock and bond returns and the funds' varying  degrees of
exposure to international stocks.

     Because the funds had larger-than-usual stakes in stocks during the period,
each  LifeStrategy  Fund outpaced its benchmark  composite  index.  The adjacent
table compares the total returns (capital change plus reinvested  distributions)
of the funds and their  benchmarks,  which are  weighted  to reflect  the target
asset  allocation  of each fund.  Two of our funds also had returns  higher than
their  composite  peer-group  averages,  as shown on page 4.

*Total  returns for the  composite  indexes  are derived by applying  the funds'
target allocations to the results of the following benchmarks:  for U.S. stocks,
the Wilshire  5000 Total Market  Index;  for  international  stocks,  the Morgan
Stanley Capital  International Europe,  Australasia,  Far East Index; for bonds,
the Lehman Brothers  Aggregate Bond Index; and for short-term  investments,  the
Citigroup 3-Month Treasury Bill Index.

     The table on page 5  presents  the  funds'  starting  and  ending net asset
values for the period, dividend distributions, and annualized yields as of April
30.  Reflecting the general  decline in interest  rates,  the funds' yields fell
somewhat over the half-year.  At the end of the period,  the yield of the Income
Fund stood at 4.24% and that of the  Conservative  Growth Fund at 3.13%.

STOCKS OPENED AND CLOSED  STRONGLY

During the six months ended April 30, 2003,  the overall U.S.  stock market,  as
measured by the Wilshire 5000 Index,  returned  5.0%, a  performance  reflecting
vigorous rallies at the beginning and end of the period.  Inside these bookends,
however,  stock prices drifted lower,  depressed by investor  apprehension about
geopolitical  tensions and the generally glum economic

news.  Although  the  U.S.military  campaign  in Iraq was brief and  successful,
economic  uncertainty  remained.  Consumer  spending stayed strong,  but the job
market  deteriorated  and the red-hot  housing  market began to cool.  The broad
economy  registered  anemic growth.
     Small stocks,  as represented by the Russell 2000 Index,  performed  better
than the large stocks in the Russell 1000 Index, while growth stocks (those that
are expected to produce  rapid  earnings  growth) and value  stocks  (those that
generally trade at below-market valuations) produced similar returns.
     Overseas,  Asian stock markets were hit  especially  hard,  but as a group,
international stocks produced a modest positive return for U.S.-based investors.

BONDS DEFIED EXPECTATIONS

Bonds  generated  surprisingly  strong results,  with the Lehman  Aggregate Bond
Index--a broad measure of the taxable bond  market--returning  4.3%. Bond yields
began the fiscal  half-year at their lowest levels in more than 40 years,  which
would  generally  portend  unimpressive  returns,  but the bond  market  rallied
further,  in part because of a strong rebound in hard-hit corporate bonds. Long-
and  intermediate-term  interest rates fell modestly during the period,  and the
yield  of the  3-month  U.S.  Treasury  bill--a  fair  proxy  for  money  market
yields--declined  34 basis  points  (0.34  percentage  point) to 1.11%.

FOR THE LIFESTRATEGY FUNDS,  INTERNATIONAL  STOCKS PLAYED AN OFFSETTING ROLE

With stocks  outperforming  bonds--albeit  not by  much--you  would expect those
LifeStrategy  funds  with the  largest  stock  allocations  to post the  highest
returns.  Obviously,  this did not happen during the fiscal half-year;  instead,
the four funds' returns were almost identical. The reason is that the funds with
higher stock allocations also had higher stakes in international  stocks,  which
performed  less  well  than  U.S.  stocks  and  U.S.  bonds.

As you know,  the  LifeStrategy  Funds invest in other Vanguard funds in varying
allocations.  Three of the four own shares of  Vanguard(R)  Total  International
Stock Index Fund,  which posted the lowest result  (+2.2%)


                                       2


among the underlying funds. The international fund accounts for about 15% of the
LifeStrategy Growth Fund's assets, with lower allocations in the Moderate Growth
and  Conservative  Growth  Funds.  This  acted as a drag on the more  aggressive
funds,  while  helping the more  conservative  funds.  The Moderate  Growth Fund
managed to find the "sweet  spot,"  giving it a slightly  higher return than the
other funds.

     Another underlying  fund--VANGUARD(R) ASSET ALLOCATION FUND--was the source
of the equity commitment that enabled the four LifeStrategy  Funds to outperform
their index  benchmarks.  While each  benchmark  includes a fixed  percentage of
stocks,  our  funds'  stakes  change  according  to the  holdings  in the  Asset
Allocation  Fund,  which  represents  one-quarter  of each  LifeStrategy  fund's
holdings.  (The table below shows the four funds' target  allocations  and their
actual  allocations  as of April  30.)

     The Asset  Allocation  Fund's  investment  adviser shifts the fund's assets
among stocks,  bonds, and money market instruments based on an assessment of the
relative  attractiveness of each asset class. By mid-2002,  the Asset Allocation
Fund was 100% invested in stocks, and--aside from a temporary and profitable 10%
bond position in December--it stayed that way throughout the LifeStrategy Funds'
fiscal half-year.  After an initial rocky spell, this equity-heavy position paid
off during the past six months. The Asset Allocation Fund gained 5.4% during the
period.

     Another underlying fund that boosted performance relative to benchmarks was
VANGUARD(R) SHORT-TERM CORPORATE FUND, which accounts for about one-fifth of the
assets of the  Income  and  Conservative  Growth  Funds.  With  corporate  bonds
rebounding,  this fund returned  3.7%--far above the 0.6% return of money market
instruments.

     Relative to their composite  peer-group  averages,  two LifeStrategy  Funds
posted  slightly  higher returns for the  half-year,  while two were on par with
their peers, as the table on page 4 shows. Over the past decade, the gap between
our funds' returns and those of the peer averages has been wider,  and we expect
it

will be again in the future.  Our confidence rests in large part upon Vanguard's
low costs. The average weighted expense ratios of the LifeStrategy  Funds (based
on the  expenses  of the  underlying  funds)  range  from  0.28%  to 0.29% on an
annualized  basis.  In comparison,  the average ratios for composite peer groups
are three to four times that--a  difficult  hurdle for  competitors  to overcome
year after year.  We note that,  unlike  many "funds of funds"  offered by other
companies,  the LifeStrategy Funds do not charge  administrative  fees on top of
the underlying funds' expense ratios.

THE BEST SOLUTION TO UNCERTAINTY MAY BE THE SIMPLEST ONE
Now that we have seen a break in the  longest  bear  market in stocks  since the
Great Depression, some investors may be asking themselves, "Is the worst finally
over?"  Neither we nor anyone else can answer  that.  We can say that stocks are
more  reasonably  priced  than they were three years ago  and--with  higher bond
prices and lower  yields--fixed  income securities are riskier than they used to
be. But no one can foretell what the markets will do in the short term. For this
reason,  we  believe  that  the  prudent  choice  is to  stick  with a  balanced
investment plan, diversified across asset classes in proportions appropriate for
the investor's situation,  goals, time horizon, and risk tolerance. The Vanguard
LifeStrategy  Funds  provide a convenient  and  low-cost  means to pursue such a
plan. Thank you for entrusting your hard-earned money to us.

GLOSSARY OF INVESTMENT TERMS

AVERAGE WEIGHTED EXPENSE RATIO.  Funds that invest in other Vanguard funds incur
no  direct  expenses,  but  do  bear  proportionate  shares  of  the  operating,
administrative,  and  advisory  expenses of the  underlying  funds.  The average
weighted  expense  ratio is the  average of these  expense  ratios,  weighted in
proportion to the amount of the fund invested in each underlying fund.
- --------------------------------------------------------------------------------
BETA. A measure of the magnitude of a fund's past  share-price  fluctuations  in
relation  to the ups and downs of the  overall  market  (or  appropriate  market
index).  The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20  typically  would have seen its share price rise or fall by 12% when the
overall market rose or fell by 10%. However, a fund's beta should be reviewed in
conjunction with its R-squared (see definition  below). The lower the R-squared,
the less correlation  there is between the fund and the benchmark,  and the less
reliable beta is as an indicator of volatility.
- --------------------------------------------------------------------------------
EXPENSE  RATIO.  The  percentage of a fund's  average net assets used to pay its
annual  administrative  and advisory  expenses.  These expenses  directly reduce
returns to investors.
- --------------------------------------------------------------------------------
R-SQUARED.  A measure of how much of a fund's past  returns can be  explained by
the returns from the overall market (or its benchmark  index). If a fund's total
returns  were  precisely  synchronized  with the overall  market's  return,  its
R-squared  would be 1.00.  If the fund's  returns  bore no  relationship  to the
market's returns, its R-squared would be 0.
- --------------------------------------------------------------------------------
YIELD.  A snapshot of a fund's  income from interest and  dividends.  The yield,
expressed  as a  percentage  of the fund's net asset  value,  is based on income
earned over the past 30 days and is  annualized,  or  projected  forward for the
coming year.

PERFORMANCE SUMMARIES AS OF APRIL 30, 2003

All of the returns in this report  represent past  performance,  which cannot be
used to predict future returns that may be achieved by the fund. Note, too, that
both share price and return can fluctuate  widely.  An investor's  shares,  when
redeemed,  could be worth more or less than their  original  cost.  The  returns
shown do not reflect taxes that a shareholder would pay on fund distributions or
on the redemption of fund shares.

FINANCIAL STATEMENTS APRIL 30, 2003 (UNAUDITED)

STATEMENT OF NET ASSETS

This Statement  provides a detailed list of each fund's investments in shares of
each Vanguard fund,  along with the value of each  investment on the last day of
the reporting period.  Other assets are added to, and liabilities are subtracted
from,  the value of Total  Investments  to  calculate  the  fund's  Net  Assets.
Finally,  Net Assets are divided by the outstanding shares of the fund to arrive
at its share price, or Net Asset Value (NAV) Per Share.

     At the end of the Statement of Net Assets, you will find a table displaying
the  composition  of the fund's net assets.  Because all income and any realized
gains must be  distributed  to  shareholders  each year,  the bulk of net assets
consists of Paid-in Capital (money invested by shareholders).  The amounts shown
for  Undistributed  Net  Investment  Income and  Accumulated  Net Realized Gains
usually   approximate   the  sums  the  fund  had  available  to  distribute  to
shareholders as income  dividends or capital gains as of the statement date. Any
Accumulated Net Realized Losses, and any cumulative excess of distributions over
net income or net realized gains, will appear as negative  balances.  Unrealized
Appreciation  (Depreciation)  is the difference  between the market value of the
fund's investments and their cost, and reflects the gains (losses) that would be
realized if the fund were to sell all of its investments at their statement-date
values.

STATEMENT OF CHANGES IN NET ASSETS

This  Statement  shows how each fund's total net assets  changed  during the two
most recent reporting periods.  The Operations  section  summarizes  information
detailed in the Statement of Operations.  The amounts shown as  Distributions to
shareholders  from the fund's net  income  and  capital  gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax  basis  and may be made in a period  different  from the one in which  the
income was earned or the gains were  realized on the financial  statements.  The
Capital Share Transactions section shows the amount shareholders invested in the
fund,  either by purchasing shares or by reinvesting  distributions,  as well as
the amounts redeemed.  The  corresponding  numbers of Shares Issued and Redeemed
are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table  summarizes  each  fund's  investment  results and  distributions  to
shareholders on a per-share  basis. The table also presents the Total Return and
shows net  investment  income and expenses as percentages of average net assets.
The expense ratio is zero because the fund pays no direct  expenses;  the fund's
share of the expenses of the other funds in which it invests  reduces the income
received from them. The data in the table will help you assess:  the variability
of the  fund's  net income and total  returns  from year to year;  the  relative
contributions  of net income and capital gains to the fund's total  return;  the
extent to which the fund tends to distribute  capital gains;  and the portion of
capital  gain  distributions  representing  the  "pass-through"  of capital gain
distributions  received  from  other  Vanguard  funds.  The table also shows the
Portfolio Turnover Rate, a measure of trading activity.  A turnover rate of 100%
means that the average  security is held in the fund for one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard LifeStrategy Funds comprise the LifeStrategy Income Fund,  LifeStrategy
Conservative  Growth Fund,  LifeStrategy  Moderate Growth Fund, and LifeStrategy
Growth Fund,  each of which is registered  under the  Investment  Company Act of
1940 as an open-end  investment  company,  or mutual  fund.  Each fund follows a
balanced  investment strategy by investing in selected Vanguard funds to achieve
its targeted allocation of assets to U.S. stocks,  international  stocks, bonds,
and short-term reserves.

A. The following  significant  accounting policies conform to generally accepted
accounting  principles for U.S. mutual funds. The funds consistently follow such
policies in preparing their financial statements.

     1.  VALUATION:  Investments  are  valued  at the net  asset  value  of each
Vanguard  fund  determined  as of the  close  of the  New  York  Stock  Exchange
(generally  4:00  p.m.  Eastern  time) on the  valuation  date.  Temporary  cash
investments are valued at cost, which approximates market value.

     2.  REPURCHASE  AGREEMENTS:  Each fund,  along  with  other  members of The
Vanguard  Group,  transfers  uninvested  cash balances to a pooled cash account,
which  is  invested  in  repurchase   agreements  secured  by  U.S.   government
securities.  Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements  mature.  Each agreement  requires that
the market value of the  collateral be sufficient to cover  payments of interest
and principal; however, in the event of default or bankruptcy by the other party
to  the  agreement,  retention  of  the  collateral  may  be  subject  to  legal
proceedings.

     3.  FEDERAL  INCOME  TAXES:  Each fund  intends to continue to qualify as a
regulated   investment  company  and  distribute  all  of  its  taxable  income.
Accordingly,  no provision for federal income taxes is required in the financial
statements.

     4.  DISTRIBUTIONS:  Distributions  to  shareholders  are  recorded  on  the
ex-dividend date.

     5. OTHER:  Income and capital gain  distributions  received are recorded on
the  ex-dividend  date.  Security  transactions  are  accounted  for on the date
securities are bought or sold.  Costs used to determine  realized gains (losses)
on the sale of investment securities are those of the specific securities sold.

B. Under a special service  agreement,  The Vanguard Group  furnishes  corporate
management,  administrative,  marketing, and distribution services to the funds.
The special service  agreement  provides that Vanguard will reimburse the funds'
expenses to the extent of savings in administrative and marketing costs realized
by Vanguard in the operation of the funds. Accordingly, all expenses incurred by
the funds  during  the six months  ended  April 30,  2003,  were  reimbursed  by
Vanguard.  The funds'  trustees and officers are also  directors and officers of
Vanguard and the funds in which the funds invest.

C.  Distributions  are  determined  on a tax  basis  and  may  differ  from  net
investment income and realized capital gains for financial  reporting  purposes.
Differences   may  be  permanent  or  temporary.   Permanent   differences   are
reclassified among capital accounts in the financial statements to reflect their
tax  character.  Temporary  differences  arise  when  certain  items of  income,
expense,  gain,  or loss are  recognized  in  different  periods  for  financial
statement and tax purposes;  these  differences will reverse at some time in the
future.  Differences  in  classification  may also result from the  treatment of
short-term gains as ordinary income for tax purposes.

                                       27

THE PEOPLE WHO GOVERN YOUR FUND

The  trustees of your mutual fund are there to see that the fund is operated and
managed in your best interests since, as a shareholder,  you are a part owner of
the fund.  Your  fund  trustees  also  serve on the  board of  directors  of The
Vanguard  Group,  Inc.,  which is owned by the  Vanguard(R)  funds and  provides
services to them on an at-cost basis.

     A majority of Vanguard's board members are  independent,  meaning that they
have no  affiliation  with  Vanguard or the funds they  oversee,  apart from the
investments they have made as private individuals. Our independent board members
bring  distinguished  backgrounds in business,  academia,  and public service to
their task of working  with  Vanguard  officers to  establish  the  policies and
oversee the activities of the funds.

     Among board members' responsibilities are selecting investment advisers for
the  funds;  monitoring  fund  operations,  performance,  and  costs;  reviewing
contracts;  nominating  and  selecting  new  trustees/directors;   and  electing
Vanguard  officers.  The dates in  parentheses  below show when each trustee was
initially elected.
