LETTER FROM THE CHAIRMAN 5/31/97
- --------------------------------------------------------------------------------


Dear Shareowner,
- --------------------------------------------------------------------------------

I am pleased to introduce this semiannual report for Pioneer International
Growth Fund, reviewing the six months from November 30, 1996, through May 31,
1997. On behalf of the Fund's investment management team, I welcome our many
new investors and thank you for your interest in the Fund.

Once again, your Fund's value-oriented management team showed that the equity
markets outside the United States offer a fruitful hunting ground for those
willing to do thorough research. The Fund's portfolio includes a mix of
companies of many sizes, located in both mature and developing economies. This
flexible approach also means the Fund seeks to achieve its results differently
than many other international funds, typically with more emphasis on emerging
markets. So far, this variety has been effective. For the semiannual period,
your Fund outperformed overseas markets as a whole, and it bested the average
gain posted by international stock funds, as reported by Lipper Analytical
Services.

As we move further into 1997, nations around the world are undergoing a number
of exciting transitions. In many countries, the stage is being set for a more
competitive and profitable business environment. What we find especially
exciting is that the Fund gives shareowners the opportunity to participate in
these developments from their earliest phases. I encourage you to read on to
learn more about Pioneer International Growth Fund and our efforts to build a
solid foundation for long-term investment success.

Please contact your investment representative, or us at 1-800-225-6292, if you
have questions about your Fund. Thank you for your support.

Respectfully,


/s/ John F. Cogan, Jr.



John F. Cogan, Jr.,
Chairman and President

Pioneer International Growth Fund
- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 5/31/97
- --------------------------------------------------------------------------------


Dear Shareowner,
- --------------------------------------------------------------------------------

The first half of Pioneer International Growth Fund's fifth fiscal year came to
a close on May 31, 1997. The Fund showed strong performance, both versus its
peers in Lipper Analytical Services' International Funds category and compared
to the Morgan Stanley Capital International (MSCI) EAFE (Europe, Australasia,
Far East) Index, an unmanaged benchmark of international stock market
performance.

Pioneer International Growth Fund's Class A Shares posted a total return of
11.59% for the six-month period, while Class B Shares returned 11.15% and Class
C Shares gained 11.19%. The 406 funds in Lipper's international fund group
returned an average of 7.90%; the MSCI EAFE Index posted a 4.19% return.
(Returns do not reflect sales charges.)

Positive factors contributing to the Fund's performance included many rising
global stock markets, which benefited from a benign inflation environment, low
interest rates and currencies that were weak relative to the U.S. dollar. Of
particular note were the emerging markets of Latin America. In Europe and
Japan, the strong dollar was positive for economic growth and corporate
competitiveness, particularly for larger companies dependent on exports.


A Value-Oriented Investment Style
Pioneer International Growth Fund invests primarily in foreign equity
securities and depositary receipts (which trade in lieu of direct stock
shares), with a widely diversified portfolio invested in both established and
emerging markets. The portfolio includes a large number of securities, more
than 200 as of May 31, which helps minimize the impact that one poorly
performing security or market can have on the portfolio. Diversification can
also help reduce the effect of some other risks of international investing,
such as economic and political instabilities, as well as currency fluctuations.
 

We use a value style of investing, preferring to buy stocks that are "cheap"
given a company's financial condition or business prospects. We employ both
bottom-up and top-down approaches in our search.

Bottom-up means looking at companies individually. Top-down refers to the
research we do on a country-by-country basis, evaluating economic and political
conditions. Combined, the methods help us find companies and countries we
believe will work effectively for the Fund.


Continued Strength in Latin America
A big reason for the Fund's recent outperformance was the allocation to the
emerging markets of Latin America, a total of 7% of equity holdings as of May
31. Brazil has made excellent progress in bringing down inflation to 8% from
astronomical levels just a few years ago. Across the rest of the region,
inflation and interest rates are also under control, encouraging investment.
And we are still finding good value in many companies. Some of the Fund's
better-performing holdings are Brazilian utilities Telecomunicacoes Brasileiras
and Centrais Electricas Brasileiras.


Europe a Steady Performer
Continental Europe also was a good place to be during the past six months. A
cultural shift seems to be taking place in Europe, with European investors -
traditionally regarded as savers - becoming investors in the equity markets.
This increasing interest in stocks helped market performance, as new money
poured into European stock markets. We attribute part of this trend to lessened
competition from the lower yields on bonds and money market instruments.
European companies are also helping themselves by focusing on improved
performance and delivering value to stockholders.

In Europe, Telecom Italia benefited from sharp gains in the Italian market
early in the period. We took profits, but maintained a sizable position because
of its reasonable valuation. Chargeurs, a French conglomerate, was another
strong performer, due to its holdings in a successful British pay television
company. We were disappointed by the performance of Sylea, a French auto parts
company, and U.K. conglomerate Cowie Group because of lackluster earnings
reports.

Japanese Market Recovering
Continuing its trend of volatility, the Japanese market gained nearly 12% in
the two months ended May 31. We are seeing signs of improvement in Japan,
although it is still troubled by political shifts and concerns about its
financial system. Overall, estimates for growth of earnings-per-share are 30%
to 40% for 1997 and 10% to 20% for 1998; the pace of these gains reflects
expectations for the cycle of economic recovery. We gradually increased the
Fund's position in Japan to 16% as of May 31; the market currently presents a
good value, around half its peak level. We had success in Japan, despite its
difficult overall environment. Careful stock selection brought some strong
performers, including Nichiei and Shohkoh Fund, two financial services firms
offering smaller loans, and multinational firms Circle K, a food retailer, and
Nintendo, the electronic game giant.


Asian Emerging Markets Lag
Many of the emerging markets of Asia were again hindered by slowing economic
growth, weaker corporate earnings growth and slowing exports. Sales slumps in
electronics and technology, combined with increased competition from Mexico,
further weakened stock prices in many Asian emerging markets. Nevertheless, we
believe they present compelling values, partly because they have underperformed
stocks based in other locales.

Some of the stronger-performing markets in this section over the past six
months were India, up over 25%, and Indonesia, up around 14%. Especially in
poorly performing markets, stock selection is key. Thailand's market dropped
nearly 40%, while Delta Electronics rose 40% over the past six months. Remember
that the volatility inherent in emerging markets can make stock prices there
move faster - both up and down - than in established markets. That's another
powerful reason for remaining invested during short-term downturns; it's nearly
impossible to predict when, or how quickly, these markets will move if
conditions improve.

A Look Ahead
We think moderate inflation, low interest rates and reasonable corporate
earnings growth will continue in the established markets of Europe and Japan.
We also see valuations in emerging markets remaining compelling, albeit for
different reasons. In Asia, depressed stock prices bring good value; in Latin
America, economic recovery continues, with the telecommunications and utilities
industries leading the way. And because of low global interest rates, there
will likely continue to be a steady flow of funds into many overseas equity
markets.

Diversification is one of our strongest allies; and it's also one of yours.
Because we don't limit our search for stocks to one part of the world, we have
the freedom to invest anywhere outside the United States - wherever we find the
strongest value. And by having Pioneer International Growth Fund in your
portfolio, you are also able to participate in the fortunes of the world's
markets. Keep a long-term perspective, and we are confident we can offer solid
long-term performance.

Respectfully,

NOTES TO FINANCIAL STATEMENTS 5/31/97
- --------------------------------------------------------------------------------


1. Organization and Significant Accounting Policies

Pioneer International Growth Fund (the Fund) is a Massachusetts business trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Fund is to seek
long-term growth of capital.

The Fund offers three classes of shares - Class A, Class B and Class C shares.
Shares of Class A, Class B and Class C each represent an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees, and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class
A, Class B and Class C shareholders, respectively.

The Fund's financial statements have been prepared in conformity with generally
accepted accounting principles that require the management of the Fund to,
among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts
of revenues and expenses during the reporting periods. Actual results could
differ from those estimates. The following is a summary of significant
accounting policies consistently followed by the Fund, which are in conformity
with those generally accepted in the investment company industry:


A. Security Valuation
   Security transactions are recorded on trade date. Each day, securities are
   valued at the last sale price on the principal exchange where they are
   traded. Securities that have not traded on the date of valuation, or
   securities for which sale prices are not generally reported, are valued at
   the mean between the last bid and asked prices. Securities for which market
   quotations are not readily available are valued at their fair values as
   determined by, or under the direction of, the Board of Trustees. Trading in
   foreign securities is substantially completed each day at various times prior
   to the close of the New York Stock Exchange. The values of such securities
   used in computing the net asset value of the Fund's shares are determined as
   of such times. Dividend income is recorded on the ex-dividend date, except
   that certain dividends from foreign securities where the ex-dividend date may
   have passed are recorded as soon as the Fund is informed of the ex-dividend
   data in the exercise of reasonable diligence. Interest income is recorded on
   the accrual basis, net of unrecoverable foreign taxes withheld at the
   applicable country rates. Temporary cash investments are valued at amortized
   cost.


28
<PAGE>

Pioneer International Growth Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------


   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes. It
   is the Fund's practice to first select for sale those securities that have
   the highest cost and also qualify for long-term capital gain or loss
   treatment for tax purposes.

   The Fund's investments in emerging markets or countries with limited or
   developing markets, may subject the Fund to greater degree of risk than in a
   developed market. Risks associated with these developing markets,
   attributable to political, social or economic factors, may affect the price
   of the Fund's investments and income generated by these investments, as well
   as the Fund's ability to repatriate such amounts. In addition, delays are
   common in registering transfers of securities in certain countries, such as
   India, and the Fund may be unable to sell portfolio securities until the
   registration process is completed.

B. Foreign Currency Translation
   The books and records of the Fund are maintained in U.S. dollars. Amounts
   denominated in foreign currencies are translated into U.S. dollars using
   current exchange rates.

   Net realized gains and losses on foreign currency transactions represent,
   among other things, the net realized gains and losses on foreign currency
   contracts, disposition of foreign currencies and the difference between the
   amount of income accrued and the U.S. dollar actually received. Further, the
   effects of changes in foreign currency exchange rates on investments are not
   segregated in the statement of operations from the effects of changes in
   market price of those securities but are included with the net realized and
   unrealized gain or loss on investments.

C. Forward Foreign Currency Contracts
   The Fund enters into forward foreign currency contracts (contracts) for the
   purchase or sale of a specific foreign currency at a fixed price on a future
   date as a hedge or cross-hedge against either specific investment
   transactions (settlement hedges) or portfolio positions (portfolio hedges).
   All contracts are marked to market daily at the applicable exchange rates,
   and any resulting unrealized gains or losses are recorded in the Fund's
   financial statements. The Fund records realized gains and losses at the time
   a portfolio hedge is offset by entry into a closing transaction or
   extinguished by delivery of the currency. Risks may arise upon entering into
   these contracts from the potential inability of counterparties to meet the
   terms of the contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar (see Note 6).


                                                                              29

- --------------------------------------------------------------------------------

D. Federal Income Taxes
   It is the Fund's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   shareholders. Therefore, no federal income tax provision is required.

   In addition to the requirements of the Internal Revenue Code, the Fund may
   also be required to pay local taxes on net realized capital gains in certain
   countries. The required capital gains taxes, if any, are determined in
   accordance with local tax laws. In determining daily net asset value, the
   Fund estimates the reserve for capital gains taxes, if any, associated with
   net unrealized gains on certain portfolio securities. The estimated reserve
   for capital gains taxes, if any, is based on the holding periods of such
   securities and the related tax rates, tax loss carryforward (if applicable)
   and other such factors.

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

E. Fund Shares
   The Fund records sales and repurchases of its shares on trade date. Net
   losses, if any, as a result of cancellations are absorbed by Pioneer Funds
   Distributor, Inc. (PFD), the principal underwriter for the Fund and an
   indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $185,646 in
   underwriting commissions on the sale of fund shares during the six months
   ended May 31, 1997.

F. Class Allocations
   Distribution fees are calculated based on the average daily net assets
   attributable to Class A, Class B and Class C shares of the Fund,
   respectively. Shareholders of each class share all expenses and fees paid to
   the transfer agent, Pioneering Services Corporation (PSC), for their
   services, which are allocated based on the number of accounts in each class
   and the ratable allocation of related out-of-pocket expense (see Note 3 ).
   Income, common expenses and realized and unrealized gains and losses are
   calculated at the Fund level and allocated daily to each class of shares
   based on the respective percentage of adjusted net assets at the beginning of
   the day.

Pioneer International Growth Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------


   Distributions to shareholders are recorded as of the ex-dividend date.
   Distributions paid by the Fund with respect to each class of shares are
   calculated in the same manner, at the same time, and in the same amount,
   except that Class A, Class B and Class C shares can bear different transfer
   agent and distribution fees.

G. Repurchase Agreements
   With respect to repurchase agreements entered into by the Fund, the value of
   the underlying securities (collateral), including accrued interest received
   from counterparties, is required to be at least equal to or in excess of the
   value of the repurchase agreement at the time of purchase. The collateral for
   all repurchase agreements is held in safekeeping in the customer-only account
   of the Fund's custodian, or subcustodians. The Fund's investment adviser,
   Pioneering Management Corporation (PMC), is responsible for determining that
   the value of the collateral remains at least equal to the repurchase price.

2. Management Agreement
PMC manages the Fund's portfolio and is a wholly owned subsidiary of PGI.
Management fees are calculated daily at the annual rate of 1.00% of the Fund's
average daily net assets up to $300 million; 0.85% of the next $200 million;
and 0.75% of excess over $500 million.

In addition, under the management agreement, certain other services and costs,
including accounting, regulatory reporting and insurance premiums, are paid by
the Fund. At May 31, 1997, $403,654 was payable to PMC related to management
fees and certain other expenses.

3. Transfer Agent
PSC, a wholly owned subsidiary of PGI, provides substantially all transfer
agent and shareholder services to the Fund at negotiated rates. Included in due
to affiliates is $106,945 in transfer agent fees payable to PSC at May 31,
1997.

4. Distribution Plans
The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the Fund's average daily net assets in reimbursement of
its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the aver-


                                                                              31

age daily net assets attributable to each class of shares. The fee consists of
a 0.25% service fee and a 0.75% distribution fee paid as compensation for
personal services and/or account maintenance services or distribution services
with regard to Class B and Class C shares. Included in due to affiliates is
$236,174 in distribution fees payable to PFD at May 31, 1997.

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within one year of
purchase. Class B shares that are redeemed within six years of purchase are
subject to a CDSC at declining rates beginning at 4.0%, based on the lower of
cost or market value of shares being redeemed. Redemptions of Class C shares
within one year of purchase are subject to a CDSC of 1.00%. Proceeds from the
CDSC are paid to PFD. For the six months ended May 31, 1997, CDSCs in the
amount of $104,871 were paid to PFD.

5. Expense Offsets
The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the six months ended May 31, 1997,
the Fund's expenses were reduced by $41,744 under such arrangements.

6. Forward Foreign Currency Contracts
At May 31, 1997, the Fund had entered into various contracts that obligate the
Fund to deliver currencies at specified future dates. At the maturity of a
contract, the Fund must make delivery of the foreign currency. Alternatively,
prior to the settlement date of a portfolio hedge, the Fund may close out such
contracts by entering into an offsetting hedge contract. Open portfolio hedges
at May 31, 1997 were as follows:

statements. Our procedures included confirmation of securities owned as of May
31, 1997 by correspondence with the custodian. 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
Pioneer International Growth Fund as of May 31, 1997, the results of its
operations, the changes in its net assets, and the financial highlights for the
periods presented, in conformity with generally accepted accounting principles.

PROGRAMS AND SERVICES FOR PIONEER SHAREOWNERS
- --------------------------------------------------------------------------------


Your investment representative can give you additional information on Pioneer's
programs and services. If you want to order literature on any of the following
items directly, simply call Pioneer at 1-800-225-6292.


FactFoneSM
Our automated account information service, available to you 24 hours a day,
seven days a week. FactFone gives you a quick and easy way to check fund share
prices, yields, dividends and distributions, as well as information about your
own account. Simply call 1-800-225-4321. For specific account information, have
your 13-digit account number and four-digit personal identification number at
hand.


90-Day Reinstatement Privilege (for Class A Shares)
Enables you to reinvest all or a portion of the money you redeem from your
Pioneer account - without paying a sales charge - within 90 days of your
redemption. You have the choice of investing in any Pioneer fund, as long as
you meet its minimum investment requirement.


Investomatic Plan
An easy and convenient way for you to invest on a regular basis. All you need
to do is authorize a set amount of money to be moved out of your bank account
into the Pioneer fund of your choice. Investomatic also allows you to change
the dollar amount, frequency and investment date right over the phone. By
putting aside affordable amounts of money regularly, you can build a long-term
investment - without sacrificing your current standard of living.


Payroll Investment Program (PIP)
Lets you invest in a Pioneer fund directly through your paycheck. All that's
involved is for your employer to fill out an authorization form allowing
Pioneer to deduct from participating employees' paychecks. You specify the
dollar amount you want to invest into the Pioneer fund(s) of your choice.

Automatic Exchange Program
A simple way to move money from a money market or bond fund into a stock fund
over a period of time. Just invest a lump sum in a Pioneer money market fund or
bond fund. Then, select the Pioneer equity fund or funds you wish to invest in,
and choose the amounts and dates for Pioneer to sell shares of your money
market or bond fund and use the proceeds to buy shares of the Pioneer equity
fund you have chosen. Over time, your original investment will be shifted to
your Pioneer equity fund.


Directed Dividends
Lets you invest cash dividends from one Pioneer fund to an account in another
Pioneer fund with no sales charge or fee. Simply fill out the applicable
information on a Pioneer Account Options Form. (This program is available for
dividend payments only; capital gains distributions are not eligible at this
time.)


Direct Deposit
Lets you move money into your bank account using electronic funds transfer
(EFT). EFT moves your money faster than you would receive a check, eliminates
unnecessary paper and mail, and avoids lost checks. Simply fill out a Pioneer
Direct Deposit Form, giving your instructions.


Systematic Withdrawal Plan (SWP)
Lets you establish automatic withdrawals from your account at set intervals.
You decide the frequency and the day of the month you want. Pioneer will send
the proceeds by check to the address you designate, or electronically to your
bank account. You also can authorize Pioneer to make the redemptions payable to
someone else. (SWPs are available only for accounts with a value of $10,000 or
more.)
