Dear Shareholders,                                              December 6, 2004

THE YEAR IN REVIEW

      It was an unusual year for investing.  Corporate  profit growth has rarely
been better, and both the U.S. and global economies expanded at a steady, stable
clip with very low  inflation  for most of the  year.  But a tight  presidential
race, war in Iraq,  rising energy and commodity prices,  and continued  investor
skepticism kept the markets muted until November.

      The fiscal year began on a positive note,  and through March,  the markets
responded  positively  to strong  manufacturing  activity  and growing  consumer
confidence.  In April the mood started to shift. Energy prices were on the rise,
economic growth led to speculation (correct as it turned out) that the Fed would
soon raise interest rates, and the situation in Iraq was not improving.  Perhaps
just as  unsettling  to the  markets,  job growth  lagged the  broader  economic
recovery.  As a  result,  the  markets  retreated  from  their  March  peak  and
progressively moved lower until August.

      By autumn,  manufacturing  activity and consumer spending had slowed.  The
price of oil continued to rise and the Fed increased  the  short-term  rate from
1.00% to 1.75% by fiscal year end (October  31,  2004).  The close  presidential
race generated  passion but also created  uncertainty,  and the markets remained
range-bound until election day. It may be a cliche,  but investors truly dislike
uncertainty,  and the markets only moved up significantly after the election was
over.

      As a result,  for the 12 months ended October 31, 2004, the equity markets
experienced modest gains with the Dow gaining 4.46%, the Nasdaq up 2.68% and the
S&P 500 up  9.42%.  The  yield on the U.S.  Treasury  10-year  note was 4.05% on
October 31, compared to 4.30% a year earlier.

PORTFOLIO MATTERS

Alger SmallCap Growth Institutional Fund

      The Alger  SmallCap  Growth  Institutional  Fund gained 6.42% for the year
ended October 31, 2004 while the Russell 2000 Growth Index returned  5.54%.  Our
holdings in the health care sector  significantly  outperformed  the  benchmark.
Intuitive Surgical, a leader in surgical robotics,  was among the top-performing
holdings.  Other top health care holdings included Immucor, which develops blood
diagnostics,  and Tularik  Inc.,  whose  primary focus is on oral drugs that use
gene regulation to fight cancer,  immune disorders and metabolic diseases.  Dade
Behring Holdings,  which makes diagnostic  testing kits, also contributed to the
sector's positive performance.

      Our holdings in the financial  sector  outperformed the benchmark with the
help of First  Marblehead  Corp.,  which  provides  services  for  student  loan
originators.  Top-performing  energy  holdings  included  oil  and  natural  gas
exploration and production  company Tom Brown, Inc. and drilling equipment maker
Varco  International.  Although our holdings in the industrials sector did quite
well, we underperformed  the benchmark.  The Fund also suffered from a number of
underperforming  stocks in the information technology sector including Fairchild
Semiconductor, Intelligroup, Inc. and Chordiant Software.


                                                                             -2-


Alger MidCap Growth Institutional Fund

      For the year ended October 31, 2004, the Alger MidCap Growth Institutional
Fund posted a return of 4.06%,  while the Russell Midcap Growth Index  increased
8.77%.   Holdings   in   the   consumer   discretionary   sector   significantly
underperformed the benchmark. The Fund suffered from DVD rental service Netflix,
which  felt the  effect of  increased  competition  and was  forced to lower its
subscription   price.   Sharper  Image  Corporation  also  detracted  from  Fund
performance.  However,  XM Satellite Radio had an exceptional year and was a top
contributor.  Our technology holdings were down with disappointing  returns from
Teradyne,  which develops semiconductor testing equipment, and Novellus Systems,
a manufacturer of semiconductor production equipment.

      Health  care stocks did quite well and  outperformed  the  benchmark.  Top
performers  included   pharmaceutical   firms  Elan  Corporation  and  Sepracor.
Industrial sector holdings significantly  outperformed the benchmark with strong
returns from defense  communications  equipment supplier L-3 and freight shipper
Yellow Roadway.

Alger LargeCap Growth Institutional Fund

      The Alger LargeCap Growth  Institutional  Fund gained 1.40% for the fiscal
year ended October 31, 2004,  compared with a gain of 3.39% for the Russell 1000
Growth Index.  Information  technology holdings averaged above market weight and
underperformed  the  benchmark.   The  semiconductor  and  software   industries
performed  poorly,  notably  Applied  Materials,  a developer  of  semiconductor
production equipment,  and Veritas, a provider of data management software.  The
exception was Google, which was the top-performing holding in the Fund.

      In the consumer  discretionary  sector, we were above market weight at 22%
of the Fund and we outperformed  the benchmark,  with Starwood Hotels and Target
two of the top  contributors.  Media  companies  also  performed  well  with the
highest  returns  coming from XM Satellite  Radio.  In Internet  retail,  online
auctioneer eBay was a top performer.  A notable  exception was online DVD rental
service Netflix, which was hit hard after lowering its subscription price due to
increased competition. In health care, we were below market weight and performed
poorly.  Our biotech  holdings were  particularly  weak, with losses in ImClone,
ICOS, and Millennium  Pharmaceuticals.  In financials, we were just below market
weight and  significantly  outperformed the benchmark with a strong showing from
investment management firms T. Rowe Price and Affiliated Managers Group.

Alger Balanced Institutional Fund

      For the year ended October 31, 2004, the Alger Balanced Institutional Fund
returned 1.27% while the Russell 1000 Growth Index returned 3.39% and the Lehman
Brothers  Government/Credit Bond Index rose 5.59%. Information technology stocks
represented  approximately  a third of the equity portion of the  portfolio.  We
significantly  underperformed the benchmark in the health care sector because of
our  holdings in ImClone  Systems and  Millennium  Pharmaceuticals.  In consumer
discretionary we were on par with the Russell benchmark.  However,  eBay's solid
performance  was not  enough to offset the loss  sustained  by our  position  in
Netflix. Although our holdings


                                                                             -3-


in industrials were below market weight,  the Fund outperformed the benchmark in
this sector largely due to Tyco International.

      The fixed-income portion of the portfolio benefited from its overweight in
corporate  bonds.  As the yield curve  flattened,  the Fund's  overweighting  in
longer-dated  Treasuries also added significantly to returns.  The Fund was able
to  capitalize  not only on  shrinking  credit  spreads,  but falling  long-term
interest rates.

Alger Socially Responsible Growth Institutional Fund

      The Alger Socially  Responsible Growth Institutional Fund gained 0.30% for
the year ended  October 31, 2004 while the Russell  3000 Growth  Index  returned
3.53% In  consumer  discretionary  holdings  we were  above  market  weight  and
slightly  underperformed the benchmark.  Contributors to performance were Sirius
Satellite  Radio and eBay,  both of which had an impressive  year. The exception
here was  online  DVD rental  service  Netflix,  which  detracted  from  overall
performance.   Although  we  were  underweight  in  the  financials  sector,  we
outperformed the benchmark due to First Marblehead's strong showing.

      While we fared  better than the  benchmark in the  information  technology
sector, our holdings were still down for the year. Semiconductor stocks were hit
hardest,  notably  Kulicke & Soffa  Industries,  Novellus  Systems,  and Applied
Materials.  In  software,  Red Hat and Veritas  also took big hits.  Research in
Motion Ltd., the creator of the widely-used,  handheld Blackberry  communication
product, was an exception.

Alger Capital Appreciation Institutional Fund

      For the fiscal year ended October 31, 2004, the Alger Capital Appreciation
Institutional  Fund lost .09% compared with a gain of 3.53% for the Russell 3000
Growth  Index.  Much of the  underperformance  was the  result of being  heavily
overweighted in information technology. While we fared better than the benchmark
in the information technology sector, our holdings were still down for the year.
Semiconductor  stocks  were hit  hardest,  notably  Kulicke & Soffa  Industries,
Novellus Systems, and Applied Materials.  In software,  Red Hat and Veritas also
took big hits. Research in Motion Ltd., the creator of the widely-used  handheld
Blackberry communication product, was an exception.

      Our  holdings in  consumer  discretionary  did  better,  and we were above
market  weight.  Satellite  radio  companies XM Satellite and Sirius both had an
impressive  year,  and online  retailer eBay was among the top performers in the
Fund. The exception here was online DVD rental service Netflix,  which detracted
from overall performance.

LOOKING AHEAD

      For the first time in many years,  we believe that the market is no longer
gripped  by the  irrational  exuberance  of the  late  1990s  or the  irrational
pessimism of the first years of the new millennium.  Instead, we think that this
market  will  reward or  penalize  companies  based on how well those  companies
perform.  As a result,  heading into 2005,  we expect to see steady and rational
gains with less volatility than in past years. In light of impressive  corporate
earnings growth and low interest rates, we believe


                                                                             -4-


that much of the market is  undervalued,  and that  companies  achieving  solid,
double-digit earnings should command better prices in the year ahead.

      At the  same  time,  employment  and  wage  gains  are  likely  to be less
impressive than corporate profit growth.  Productivity  remains high by historic
averages,  and companies have not needed to initiate  substantial new hiring. In
addition,  higher  energy  prices look to be a mild check on what is otherwise a
very robust  economy.  While the pace of growth should slow from its pace a year
ago, corporate profits overall should grow in the high single-digits,  with many
companies significantly exceeding that. GDP growth should be at least 3%.

      Alger is  celebrating  its 40th  anniversary  of managing  money,  and our
investment philosophy and process remain the same. This year, however, was a bit
disappointing to us. Uncertainty trumped fundamentals,  and our stocks didn't do
as well as we had  expected.  Looking  back,  perhaps this was simply the "pause
that  refreshes." In the rally following the election,  both the markets and our
performance have picked up considerably.  We think this is a positive  harbinger
for 2005.

      As always, we will continue to use our time-tested,  disciplined  approach
in order to identify  dynamic  companies  and invest in them. We value the trust
you have placed in us, and we thank you. We look forward to the year ahead.

      Respectfully submitted,

THE ALGER INSTITUTIONAL FUNDS
SHAREHOLDER EXPENSE EXAMPLE (UNAUDITED)

      As a shareholder  of the Fund,  you incur two types of costs:  transaction
costs, if applicable, and ongoing costs, including management fees, distribution
(12b-1) fees, if applicable,  and other fund expenses.  This example is intended
to help you understand  your ongoing costs (in dollars) of investing in the Fund
and to compare  these costs with the ongoing  costs of investing in other mutual
funds.

      The  example  below is based on an  investment  of $1,000  invested at the
beginning of the six-month  period  starting May 1, 2004 and ending  October 31,
2004.

ACTUAL EXPENSES

      The  first  line for each  class of shares  in the  table  below  provides
information  about actual  account values and actual  expenses.  You may use the
information in this line, together with the amount you invested, to estimate the
expenses  that you would have paid over the period.  Simply  divide your account
value by $1,000 (for example,  an $8,600 account value divided by $1,000 = 8.6),
then  multiply  the result by the  number in the first  line  under the  heading
entitled  "Expenses Paid During the Period" to estimate the expenses you paid on
your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

      The  second  line for each  class of shares in the  table  below  provides
information about hypothetical account values and hypothetical expenses based on
the Fund's actual expense ratios for each class of shares and an assumed rate of
return of 5% per year before  expenses,  which is not the Fund's actual  return.
The  hypothetical  account  values and  expenses may not be used to estimate the
actual ending account  balance or expenses you paid for the period.  You may use
this information to compare the ongoing costs of investing in the Fund and other
funds. To do so, compare this 5%  hypothetical  example with the 5% hypothetical
examples that appear in the shareholder reports of other funds.

      Please note that the  expenses  shown in the table are meant to  highlight
your ongoing costs only and do not reflect any transaction costs. Therefore, the
second  line  under  each  class of shares  in the table is useful in  comparing
ongoing costs only,  and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.


                                                                             -6-

The  chart  above  illustrates  the  growth in value of a  hypothetical  $10,000
investment  made in the Alger LargeCap Growth  Institutional  Class I shares and
the Russell  1000 Growth  Index for the ten years ended  October 31,  2004.  The
figures  for the Alger  LargeCap  Growth  Institutional  Class I shares  and the
Russell  1000  Growth  Index  (an  unmanaged  index of  common  stocks)  include
reinvestment   of  dividends.   Performance   for  the  Alger  LargeCap   Growth
Institutional  Class R shares  may vary  from the  results  shown  above  due to
differences in expenses the class bears.

the Russell  2000 Growth  Index for the ten years ended  October 31,  2004.  The
figures  for the Alger  SmallCap  Growth  Institutional  Class I shares  and the
Russell  2000  Growth  Index  (an  unmanaged  index of  common  stocks)  include
reinvestment   of  dividends.   Performance   for  the  Alger  SmallCap   Growth
Institutional  Class R shares  may vary  from the  results  shown  above  due to
differences in expenses the class bears.

bonds) include  reinvestment of dividends and/or  interest.  Performance for the

THE ALGER INSTITUTIONAL FUNDS
NOTES TO FINANCIAL STATEMENTS

NOTE 1--GENERAL:

      The Alger Institutional Funds (formerly The Alger Institutional Fund) (the
"Trust"), is a diversified,  open-end registered investment company organized as
a business trust under the laws of the Commonwealth of Massachusetts.  The Trust
operates as a series company and currently  issues an unlimited number of shares
of beneficial interest in six funds--LargeCap Growth Fund, SmallCap Growth Fund,
MidCap  Growth  Fund,  Capital  Appreciation  Fund,  Balanced  Fund and Socially
Responsible Growth Fund (the "Funds").  Prior to February 28, 2004, the LargeCap
Growth Fund was the LargeCap Growth Portfolio,  the SmallCap Growth Fund was the
Small Cap Portfolio, the MidCap Growth Fund was the MidCap Growth Portfolio, the
Capital Appreciation Fund was the Capital Appreciation  Portfolio,  the Balanced
Fund was the Balanced Portfolio and the Socially Responsible Growth Fund was the
Socially Responsible Growth Portfolio. The LargeCap Growth Fund, SmallCap Growth
Fund, MidCap Growth Fund,  Capital  Appreciation  Fund and Socially  Responsible
Growth Fund  normally  invest  primarily  in equity  securities  and each has an
investment  objective of long-term  capital  appreciation.  The Balanced  Fund's
investment  objectives  are current  income and long-term  capital  appreciation
which  it seeks  to  achieve  through  investing  in  equity  and  fixed  income
securities.

      Each Fund  offers  Class I and Class R shares.  Class R shares  were first
offered January 27, 2003. Each class has identical rights to assets and earnings
except that only Class R shares have a plan of distribution and bear the related
expenses.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

(A)  INVESTMENT  VALUATION:  Investments of the Funds are valued on each day the
New  York  Stock  Exchange  (the  "NYSE")  is open as of the  close  of the NYSE
(currently 4:00 p.m. Eastern time). Listed securities for which such information
is  regularly  reported are valued at the last  reported  sales price or, in the
absence of reported  sales,  at the mean  between the bid and asked price or, in
the absence of a recent bid or asked price,  the equivalent as obtained from one
or more of the major market makers for the  securities to be valued.  Securities
included within the Nasdaq market shall be valued at the Nasdaq official closing
price (NOCP) on the day of valuation, or if there be no NOCP issued, at the last
sale price on such day.  Securities  included within the Nasdaq market for which
there is no NOCP and no last sale price on the day of valuation  shall be valued
at the mean between the last bid and asked prices on such day.

      Securities  for which  market  quotations  are not readily  available  are
valued at fair  value,  as  determined  in good  faith  pursuant  to  procedures
established by the Board of Trustees.


                                                                            -51-


THE ALGER INSTITUTIONAL FUNDS
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

      Short-term  securities  having a remaining  maturity of sixty days or less
are valued at amortized cost which approximates  market value.  Shares of mutual
funds are valued at the net asset value of the underlying mutual fund.

(B) SECURITIES  TRANSACTIONS AND INVESTMENT INCOME:  Securities transactions are
recorded  on a trade  date  basis.  Realized  gains and losses  from  securities
transactions  are  recorded on the  identified  cost basis.  Dividend  income is
recognized  on the  ex-dividend  date and interest  income is  recognized on the
accrual basis.

      Premiums  and  discounts on debt  securities  purchased  are  amortized or
accreted over the lives of the respective securities.

(C)  REPURCHASE  AGREEMENTS:  The Funds enter into  repurchase  agreements  with
approved  institutions.  The repurchase  agreements are  collateralized  by U.S.
Government securities, which are either received and held in physical possession
by the custodian or received by such  custodian in  book-entry  form through the
Federal  Reserve  book-entry  system.  The collateral is valued on a daily basis
during the term of the  agreement to ensure that its value equals or exceeds the
agreed-upon repurchase price to be repaid to the Funds. Additional collateral is
obtained when necessary.

(D) LENDING OF FUND  SECURITIES:  The Funds lend their  securities  to financial
institutions,  provided that the market value of the securities  loaned will not
at any time exceed one third of a Fund's  total  assets,  as defined.  The Funds
earn fees on the  securities  loaned.  In order to protect  against  the risk of
failure  by the  borrower  to return the  securities  loaned or any delay in the
delivery of such  securities,  the loan is  collateralized  by cash,  letters of
credit or U.S.  Government  securities that are maintained in an amount equal to
at least 100 percent of the current market value of the loaned  securities.  The
market value of the loaned  securities is determined at the close of business of
the Funds and any required  additional  collateral  is delivered to the Funds on
the next business day. As of October 31, 2004, there were no securities on loan.

(E) DIVIDENDS TO SHAREHOLDERS: Dividends payable to shareholders are recorded on
the ex-dividend  date. With respect to all Funds,  dividends from net investment
income  and  distributions  from net  realized  gains,  offset by any loss carry
forward,  are  declared  and paid  annually  after the end of the fiscal year in
which earned.

      Each class is treated  separately in determining  the amounts of dividends
of net investment income and capital gains payable to holders of its shares.

      The  characterization  of  distributions  to  shareholders  for  financial
reporting  purposes is determined in accordance  with federal  income tax rules.
Therefore,  the  source  of  the  Funds'  distributions  may  be  shown  in  the
accompanying financial statements as either from, or in excess of net investment
income,  net  realized  gain on  investment  transactions  or return of capital,
depending on the type of book/tax  differences that may exist.  Capital accounts
within the


                                                                            -52-


THE ALGER INSTITUTIONAL FUNDS
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

financial   statements   are  adjusted  for  permanent   book/tax   differences.
Reclassifications  result primarily from the differences in tax treatment of net
operating   losses  and  amortization   adjustments  on  debt  securities.   The
reclassifications  had no impact  on the net  asset  values of the Funds and are
designed to present the Funds' capital accounts on a tax basis.

(F)  FEDERAL  INCOME  TAXES:  It is  each  Fund's  policy  to  comply  with  the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies and to distribute all of its investment  company taxable income to its
shareholders.  Provided a Fund maintains such compliance,  no federal income tax
provision is required. Each Fund is treated as a separate entity for the purpose
of determining such compliance.

(G)  ALLOCATION   METHODS:   The  Trust  accounts  separately  for  the  assets,
liabilities and operations of each Fund. Expenses directly  attributable to each
Fund are charged to that Fund's operations; expenses which are applicable to all
Funds are  allocated  among  them  based on net  assets.  Income,  realized  and
unrealized gains and losses,  and expenses of each Fund, are allocated among the
Fund's classes based on relative net assets,  with the exception of distribution
fees, which are only applicable to Class R shares.

(H)  INDEMNIFICATION:  The Trust enters into contracts that contain a variety of
indemnification   provisions.   The  Trust's   maximum   exposure   under  these
arrangements  is unknown.  The Trust does not  anticipate  recognizing  any loss
related to these arrangements.

(I) OTHER:  These  financial  statements  have been prepared using estimates and
assumptions that affect the reported amounts therein.  Actual results may differ
from those estimates.

(A)  INVESTMENT  MANAGEMENT  FEES:  Fees incurred by each Fund,  pursuant to the

basis were as follows:

capital loss  carryforwards  which expire as set forth in the table below. These

their utilization or expiration.

NOTE 8--REGULATORY MATTERS AND LEGAL PROCEEDINGS:

      Alger  Management  has been  responding  to inquiries,  document  requests
and/or  subpoenas  from  regulatory  authorities,  including  the United  States
Securities  and Exchange  Commission  ("SEC"),  the Office of the New York State
Attorney  General,  and the Attorney  General of New Jersey,  in connection with
their  investigation  of practices  in the mutual fund  industry  identified  as
"market timing" and "late  trading."  Alger  Management has assured the board of
the Trust that if it be determined that improper trading  practices in the Trust
detrimentally  affected its performance,  Alger Management will make appropriate
restitution.  At the present  time,  Alger  Management is unable to estimate the
impact, if any, that the outcome of these investigations may have on the Trust's
results of operations or financial condition.

      Certain civil actions have developed out of the regulatory investigations.
Several purported class actions and shareholder derivative suits have been filed
against various parties, including,  depending on the lawsuit, Alger Management,
certain of the mutual  funds  managed by Alger  Management  (the  "Alger  Mutual
Funds"), and certain current and former Alger Mutual Fund trustees and officers,
alleging wrongful  market-timing and late-trading  activities.  These cases have
been transferred to the U.S. District Court of Maryland by the Judicial Panel on
Multidistrict  Litigation for consolidated pre-trial  proceedings.  On September
29,  2004,   consolidated   amended  complaints   involving  these  cases  --  a
Consolidated Amended Fund Derivative Complaint (the "Derivative  Complaint") and
two  substantially   identical  Consolidated  Amended  Class  Action  Complaints
(together,  the "Class Action  Complaint") -- were filed in the Maryland federal
district court under the caption number 1:04-MD-15863 (JFM).

      The Derivative Complaint,  brought on behalf of the Alger Mutual Funds and
Castle  Convertible  Fund,  Inc., a registered  closed-end fund managed by Alger
Management,  alleges (i) violations,  by Alger Management and,  depending on the
specific offense alleged,  by its immediate parent the Distributor (Fred Alger &
Company,  Incorporated)  and/or the fund trustee defendants,  of Sections 36(a),
36(b), 47, and 48 of the Investment  Company Act of 1940 and of Sections 206 and
215 of the Investment Advisers Act of 1940, breach of fiduciary duty, and breach
of contract, (ii) various offenses by other, unrelated,  third-party defendants,
and (iii) unjust enrichment by all the named defendants, all by virtue of


                                                                            -60-

the alleged wrongful  market-timing and late-trading  activities.  The complaint
seeks,  among  other  things,  removal of the  trustee  defendants  and of Alger
Management,  certain  rescissory  relief,  disgorgement  of management  fees and
allegedly  unlawful profits,  compensatory and punitive  monetary  damages,  and
plaintiffs'  fees and expenses  (including  attorney and expert fees). The Class
Action  Complaint  names the  Alger-related  defendants  named in the Derivative
Complaint as well as certain  defendants not named in the Derivative  Complaint,
including  certain  entities  affiliated  with Alger  Management,  certain Alger
Mutual Funds,  including the Trust, and certain additional former trustees and a
former officer of the defendant Alger Mutual Funds. It alleges,  on the basis of
factual allegations similar to those of the Derivative Complaint with respect to
the Alger defendants,  (i) offenses by Alger defendants similar to those alleged
in  the  Derivative  Complaint,  (ii)  violations,  by  Alger  Management,   the
Distributor,  their affiliates,  the funds named as defendants,  and the current
and former fund trustees and officers,  of Sections 11, 12(a)(2),  and 15 of the
Securities Act of 1933,  Sections 10(b) (and Rule 10b-5 thereunder) and 20(a) of
the Securities Exchange Act of 1934, and Section 34(b) of the Investment Company
Act of 1940, (iii) breach of contract by the funds named as defendants, and (iv)
unjust  enrichment by all of the named  defendants.  It seeks relief  similar to
that sought in the Derivative Complaint.

      Alger  Management  does not  believe  that  the  foregoing  lawsuits  will
materially  affect its ability to perform its  management  contracts with any of
the funds that it manages, and the management of the Trust believes that it will
not be materially adversely affected by the pending lawsuits.


                                                                            -61-


             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
  The Alger Institutional Funds:

      We have audited the  accompanying  statements  of assets and  liabilities,
including  the  schedules  of  investments,  of The  Alger  Institutional  Funds
(comprising the LargeCap Growth  Institutional,  SmallCap Growth  Institutional,
MidCap  Growth  Institutional,  Capital  Appreciation  Institutional,   Balanced
Institutional,    and   Socially   Responsible   Growth   Institutional   Funds)
(collectively,  the "Funds"), as of October 31, 2004, and the related statements
of operations  for the year then ended,  the statements of changes in net assets
for each of the two years in the period then ended, and the financial highlights
for each of the three years in the period then ended. These financial statements
and financial  highlights are the responsibility of the Funds'  management.  Our
responsibility  is to  express  an opinion  on these  financial  statements  and
financial  highlights based on our audits. The financial  highlights for the two
years ended October 31, 2001 were audited by other auditors, whose report, dated
November  30,  2001,   expressed  an  unqualified  opinion  on  those  financial
highlights.

      We conducted  our audits in  accordance  with the  standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain  reasonable  assurance about whether the
financial statements and financial highlights are free of material misstatement.
An audit includes  examining,  on a test basis,  evidence supporting the amounts
and  disclosures  in the  financial  statements  and financial  highlights.  Our
procedures included confirmation of investments owned as of October 31, 2004, by
correspondence  with the custodian and brokers. An audit also includes assessing
the accounting principles used and significant estimates made by management,  as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements and financial highlights referred
to above,  and audited by us,  present  fairly,  in all material  respects,  the
financial  position of The Alger  Institutional  Funds at October 31, 2004,  the
results of their  operations  for the year then ended,  the changes in their net
assets for each of the two years in the period  then  ended,  and the  financial
highlights  for each of the three years in the period then ended,  in conformity
with U.S. generally accepted accounting principles.
