                                                          Inception: May 1, 1996

Small Cap Emerging Growth Fund (FORMERLY SMALL CAP EQUITY FUND)
Wellington Management Company, LLP                              Steven C. Angeli
- --------------------------------------------------------------------------------

..    In 2003, the Fund returned 48.83%, outperforming its custom benchmark.
..    On May 1st, the sub-advisor was changed to Wellington Management Co. Since
     that date, the Fund has outperformed its benchmark, the Russell 2000 Growth
     Index.
..    Since May 1st, the Fund outperformed its benchmark due to favorable stock
     selection decisions, while sector allocation decisions detracted. Stock
     selection in the health care sector was the biggest contributor, followed
     by the information technology sector. The Fund's modest allocation to cash
     was the biggest detractor to relative returns, as all other sectors had
     positive returns.
..    The Fund's exposure to health care was the largest contributor to absolute
     performance, followed by information technology. There were no detractors
     to absolute returns since all sectors had positive absolute returns.
..    The top and bottom contributors to absolute returns came from a variety of
     sectors. The biggest contributors to performance were Red Hat, ASE Test,
     and HealthExtras. The main detractors included Enterasys Networks and
     Hollywood Entertainment Corp.
..    At year-end, the portfolio was overweight the consumer discretionary
     sector, while underweight in the information technology sector.
..    The manager employs bottom-up, fundamental research to identify
     attractively valued growth stocks. The Fund's sector allocations are
     broadly diversified but are primarily driven by stock selection.

*    Total returns are for the period ended December 31, 2003. Returns represent
     past performance, assume reinvestment of all distributions and are not
     indicative of future performance. Investment returns and principal value of
     fund shares will fluctuate so that shares, when redeemed, may be worth more
     or less than their original cost. Small-company investing entails special
     risks as outlined in the prospectus. The performance of the fund on this
     page is reported net of Trust level charges (i.e. investment management
     fees and operating expenses). It does not reflect expense and charges of
     the applicable separate accounts and variable products, all of which vary
     to a considerable extent and are described in your product prospectus.
     Performance would be lower if expenses and charges of the separate accounts
     and products were reflected.

(a)  The amount shown at this caption for each share outstanding throughout the
     year may not accord with the change in the aggregate gains and losses in
     the portfolio securities for the year because of the timing of the
     purchases and withdrawals of the shares in relation to the fluctuating
     market values of the portfolio.

(b)  The performance does not reflect expenses and charges of the applicable
     separate accounts and variable products, all of which vary to a
     considerable extent and are described in your product's prospectus.

(c)  The Fund entered into a new sub-advisory agreement with Capital Guardian
     Trust Company during the period shown.

(d)  Expense ratio is net of expense reimbursements. Had such reimbursements not
     been made the expense ratio would have been 1.21%, 1.04%, 1.02%, .95%, and
     .96%, for the years ended December 31, 2003, 2002, 2001, 2000, and 1999,

JOHN HANCOCK VARIABLE SERIES TRUST I

(000's Omitted)

NOTE A--ORGANIZATION

     John Hancock Small Cap Emerging Growth Fund, (formerly John Hancock Small
Cap Equity), (the "Fund") is a diversified series of John Hancock Variable
Series Trust I (the "Trust"), an open-end investment management company
registered under the Investment Company Act of 1940. The Trust is organized as a
Massachusetts business trust and consists of thirty different funds as of
December 31, 2003. The results of this Fund are included in this report. The
results of the other Funds in the Trust are presented under separate cover. The
Trust may add or delete Funds in the future to accommodate various investment
objectives. The Trust has issued shares of beneficial interest exclusively to
John Hancock Variable Life Account U ("JHVLAU"), John Hancock Variable Life
Account V ("JHVLAV"), John Hancock Variable Life Account S ("JHVLAS"), and John
Hancock Variable Annuity Account I ("JHVAAI") to fund policies and contracts
issued by the John Hancock Variable Life Insurance Company ("JHVLICO"), and to
John Hancock Variable Annuity Account U ("JHVAAU"), John Hancock Variable
Annuity Account V ("JHVAAV"), John Hancock Variable Life Account UV ("JHVLAUV"),
John Hancock Variable Annuity Account H ("JHVAAH"), and John Hancock Variable
Annuity Account JF ("JHVAAJF") to fund contracts and policies issued by John
Hancock Life Insurance Company ("John Hancock" or "JHLICO"), to John Hancock
Variable Life Account PPM-1 ("PPM-1"), and to John Hancock Variable Life Account
PPM-2 ("PPM-2").

NOTE B--ACCOUNTING POLICIES

     Valuation of investments: Common stocks and other such securities traded on
national exchanges are normally valued on the basis of closing prices.
Securities traded in the over-the-counter market and securities with no sales on
the day of valuation are normally valued at their last available bid price.

     Short-term investments, with a maturity not to exceed 60 days, are valued
at amortized cost, which approximates market value.

     Investment securities for which no current market quotations are readily
available, including certain foreign securities, when held by the Fund, are
valued at fair value as determined in good faith by the Board of Trustees.
Investment security transactions are recorded on the date of purchase or sale.

     Repurchase agreements: The Fund may enter into repurchase agreements which
are contracts under which the Fund would acquire a security for a relatively
short period (usually not more than 7 days) subject to the obligation of the
seller to repurchase and the Fund to resell such security at a fixed time and
price (representing the Fund's cost plus interest). The Fund will enter into
repurchase agreements only with member banks of the Federal Reserve System and
with "primary dealers" in United States Government Securities. The underlying
securities, which represent the collateral of the agreement, must be marked to
market daily to ensure that each repurchase agreement is fully collateralized at
all times. The Fund will not invest more than 10% of its net assets in
repurchase agreements maturing in more than 7 days.

     Joint trading account: Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the order permits the Fund to pool daily
uninvested cash balances into a joint account for the purpose of investing the
cash balances in short-term repurchase agreements, commercial paper and other
short-term investments which in no event will have a maturity in excess of 7
days. Joint account holdings as of December 31, 2003 are as follows:

     Expenses: Expenses directly attributable to the Fund are charged to the
Fund. Expenses not directly attributed to the Fund are allocated on the basis of
relative net assets of the Fund.

     Bank borrowings: The Fund is permitted to have bank borrowings for
temporary or emergency purposes, including the meeting of redemption requests
that otherwise might require the untimely disposition of securities. The Fund
has entered into syndicated line of credit agreements with State Street Bank and
Trust Company ("SSBT"), the Trust's record keeper and custodian and the Bank of
New York. These agreements enable the Fund to participate in an unsecured line
of credit, which permits borrowings up to $125 and $75 million, respectively.
Interest is charged to the Fund, based on its borrowing. In addition, a
commitment fee is charged to the Fund based on the average daily unused portion
of the line of credit and is allocated among the participating Funds in the
Trust. Interest expense paid under the line of credit is included under the
caption "Other fees" in the Statement of Operations.

     The Fund had borrowings under the line of credit during the year ended
December 31, 2003 as follows:

Average Daily Loan Balance
During the Period for which   Weighted Average
  Loans were Outstanding       Interest Rate     Interest Expense
- ---------------------------   ----------------   ----------------
           $382                    1.75%               $--

     Securities lending: The Fund has entered into an agreement with SSBT to
lend its securities to certain qualified brokers who pay the Fund's negotiated
lender fees. This loan is collateralized at all times with cash or securities
with a market value at least equal to the market value of the securities on
loan. Cash collateral is invested in a short-term instrument. As with other
extensions of credit, the Fund may bear the risk of delay of the loaned
securities in recovery or even loss of rights in the collateral should the
borrower of the securities fail financially. At December 31, 2003, the market
value of the securities loaned and the market value of the collateral for the
Fund was as follows:

Value of Securities Loaned   Value of Collateral
- --------------------------   -------------------
         $19,013                   $19,675

     Financial futures contracts: The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. At the time the Fund enters into a financial futures
contract, it will be required to deposit with its custodian a specified amount
of cash or U.S. government securities, known as "initial margin". Each day, the
futures contract is valued at the official settlement price of the Chicago Board
of Trade or U.S. commodities exchange. Daily adjustments, called variation
margin, arising from this "mark to market", are recorded by the Fund as
unrealized gains or losses.

NOTE B--ACCOUNTING POLICIES--Continued

     When the contracts are closed, the Fund recognizes a gain or a loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuations imposed by an exchange. At December 31, 2003, the Fund had no open
financial futures contracts.

     Forward foreign currency contracts: The Fund may use forward foreign
currency contracts to facilitate transactions in foreign securities and to
manage the Fund's currency exposure. Contracts to buy generally are used to
acquire exposure to foreign currencies, while contracts to sell are used to
hedge the Fund's investments against currency fluctuations. Neither type of
forward foreign currency transaction will eliminate fluctuations in the prices
of the Fund's securities or prevent loss if the price of such securities should
decline. The U.S. dollar value of a forward foreign currency contract is
determined using forward exchange rates supplied by a quotation service.
Realized gain (loss) on the purchases and sales of forward foreign currency
contracts is recognized on settlement date. At December 31, 2003, the Fund had
no open forward foreign currency contracts.

     Federal income taxes: The Fund intends to comply with the requirements of
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to
shareholders. Therefore, no federal income tax provision is required.

     As of December 31, 2003, the Fund had approximate net tax basis capital
loss carryforwards, which may be applied against any net taxable gains, as
follows: $11,459, $2,741 and $7,997 which expire in 2009, 2010 and 2011,
respectively.

     In addition, from the period November 1, 2003 through December 31, 2003,
the Fund incurred no net realized capital losses.

     Dividends, Interest and Distributions: Dividend income is recorded on the
ex-dividend date and interest income is recorded on the accrual basis. Realized
gains and losses from security transactions are determined on the basis of
identified cost.

     Dividends of net investment income will be declared and distributed monthly
by the Fund. The Fund will distribute all of its net realized capital gains
annually, at the end of its fiscal year.

     Estimates: The preparation of the financial statements in conformity with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

NOTE C--INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

     On February 5, 2003, the Board of Trustees of the Trust renewed its
Investment Advisory Agreement with John Hancock. For its services, John Hancock
receives monthly compensation at the following rate on an annual basis of the
Fund's net assets:

- ------------------   ------------
       1.05%             1.00%

     In the event that normal operating expenses of the Fund, exclusive of
investment advisory fees, taxes, interest, brokerage commissions and
extraordinary expenses, shall exceed 0.10% of the Fund's daily net asset value,
John Hancock and JHVLICO will reimburse the Fund for such excess. Accordingly,
for the year ended December 31, 2003, the reimbursements paid from John Hancock
and JHVLICO were $62 to the Fund.

     The Fund entered into a commission recapture program, which enables it to
pay some of its operational expenses by recouping a portion of the commissions
it pays to a broker that is not a related party of the Fund. Expenses paid
through this program may include costs of custodial, transfer agency or
accounting services. The impact of this arrangement was a reduction of $6.

     John Hancock has entered into a Sub-Advisory Agreement with Wellington
Management Company LLP, with respect to the Fund. Wellington Management Company
LLC is an affiliate of John Hancock, and under its supervision, is responsible
for the day-to-day investment management of the Fund.

     Signator Investors, Inc., a wholly owned subsidiary of John Hancock is the
principal underwriter and transfer agent of the Trust. Certain officers and
trustees of the Trust are officers and directors of JHVLICO, JHVLAU, JHVLAV, JHV
LAS, JHVAAI, JHVLAUV, JHVAAV, JHVAAU, JHVAAH, JHVAAJF, PPM-1, and PPM-2, and
some are also officers of John Hancock. Fees for independent trustees are paid
by the Trust.

NOTE D--INVESTMENT TRANSACTIONS

     Purchases and proceeds from sales and maturities of investments, excluding
short-term securities and obligations of the U.S. government, for the Fund for
the year ended December 31, 2003 were as follows:

Purchases   Sales and Maturities
- ---------   --------------------
 $158,267         $149,263

     The identified cost of investments owned by the Fund (including earned
discount on corporate short-term notes, commercial paper and collateral for
securities lending) and their respective gross unrealized appreciation and
depreciation for Federal income tax purposes at December 31, 2003 were as
follows:

NOTE D--INVESTMENT TRANSACTIONS--Continued

     Distribution of Income and Gains: Distributions of net investment income,
if any, are made at least annually. Net realized gains from investment
transactions, in excess of available capital loss carryforwards, would be
taxable to the Fund if not distributed, and, therefore, will be distributed to
shareholders at least annually. Earnings and profits distributed to shareholders
on redemption of fund shares may be utilized by the Fund, to the extent
permissible, as part of the Fund's dividends-paid deduction on its federal
income tax return.

     The timing and characterization of certain income and capital gains
distributions are determined annually in accordance with federal tax
regulations. As a result, net investment income (loss) and net realized gain
(loss) on investment transactions for a reporting period may differ
significantly from distributions during such period. These differences primarily
relate to certain securities sold at a loss. Additionally, as a result, net
investment income (loss) and net realized gain (loss) on investment transactions
for a reporting period may differ significantly from distributions during such
period. Accordingly, the Fund may periodically make reclassifications among
certain of its capital accounts without impacting the net asset value of the
Fund.

     At December 31, 2003, the Fund's components of distributable earnings on a
tax basis were as follows:

Undistributed   Undistributed
   Ordinary     Net Long-Term    Capital Loss   Net Unrealized
    Income       Capital Gain   Carryforwards    Appreciation
- -------------   -------------   -------------   --------------
     $--             $--           $22,197          $13,781

     In addition, the tax character of distributions paid by the Fund are
summarized as follows:

       Distributions from     Distributions from
Year     Ordinary Income    Long-Term Capital Gain   Return of Capital
- ----   ------------------   ----------------------   -----------------

NOTE E--OTHER MATTERS (UNAUDITED)

amended, requires registered management investment companies to furnish

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

To the Contractowners, Policyholders, and
Board of Trustees of
John Hancock Variable Series Trust I

     We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of the Small Cap Emerging Growth Fund
(formerly, Small Cap Equity Fund) (a portfolio included in the series of John
Hancock Variable Series Trust I {the "Trust"}) as of December 31, 2003, and the
related statement 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 five years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the 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. Our procedures included confirmation of securities
owned as of December 31, 2003, by correspondence with the custodian and brokers,
or by other appropriate auditing procedures where replies from brokers were not
received. 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 present fairly, in all material respects, the financial position of the

The John Hancock Variable Series Trust I consists of funds used as investment
options for various John Hancock variable life and variable annuity contracts.
Investors are not able to invest directly in the John Hancock Variable Series
Trust I.

If the total investment return for any fund for any given year appears unusually
high, the return may be attributable to unusually favorable market conditions
which will probably not be sustainable. For instance, a high total investment
return may reflect participation in IPOs, "hot" industries (e.g.,
internet-related companies), private placements, and/or leveraging investment
techniques during the period indicated. There is no assurance that any of those
methods, or any other investment technique will continue to have the same impact
on the fund's total investment returns.

All of the funds (except bond funds and equity index funds) may participate in
initial public offerings (IPOs). Under certain market conditions, such
participation could significantly improve a fund's total investment return.
There is no assurance that such market conditions will continue and provide the
same favorable impact on future investment returns.

Please refer to the prospectus for your product for additional information about
the investment options available. Variable life insurance and variable annuities
are sold by prospectus. These reports may be used as sales literature when
preceeded or accompanied by the funds' prospectus, which detail charges,
investment objectives, and operating policies.

Insurance products are issued by John Hancock Life Insurance Company, or John
Hancock Variable Life Insurance Company* (*not licensed in New York), Boston, MA
02117. Securities products are distributed by Signator Investors, Inc., Member
NASD, SIPC, 197 Clarendon Street, Boston, MA 02116.
