Important Information

Through  our  ongoing  efforts to reduce  expenses  and  respond to  shareholder
requests, your annual and semiannual report mailings are "streamlined." One copy
of each report is sent to each address,  rather than to every registered  owner.
For many  shareholders  and their families,  this eliminates  duplicate  copies,
saving paper and postage costs to the Fund.

If you are the  primary  shareholder  on at least  one  account,  prefer  not to
participate in streamlining, and would like to continue receiving one report per
registered account owner, you may request this in writing to:

            USAA Investment Management Company
            Attn: Report Mail
            9800 Fredericksburg Road
            San Antonio, TX 78284-8916

or phone a Mutual Fund Representative at 1-800-531-8448 during business hours.

This  report is for the  information  of the  shareholders  and  others who have
received a copy of the currently  effective  prospectus of the USAA World Growth
Fund,  managed by USAA Investment  Management  Company (IMCO). It may be used as

Message from the President

A year ago my message  to you sent a  cautionary  note  about a market  that had
risen very high for a long time:

       "It would  not be  unusual  if the  market  were to finish  1997
       with a return well below that of '95 and '96."

Of  course,  1997's  stock  market  did not  perform  poorly,  and we are  still
pondering when a correction  might come.  This  situation is  tailor-made  for a
discussion of risk.

There has long been a difference  between what most  investors  perceive as risk
and what academics  mean by risk. To the  individual  investor risk means losing
money. To the student risk means  variability of returns,  both up and down. The
difference can be quite important.

To a person who perceives risk as only the possibility of loss, timing becomes a
rather  attractive  proposition.  You know with  certainty  when the  market has
provided  an  exceptional  return for a given  period.  If your chief goal is to
avoid a loss,  then a  movement  to safety  following  such a period  could make
sense. But look at the experience of 1995, 1996 and 1997. Even 1998 is testimony
to the frailty of forecasting and also to an academic definition of risk.

If market risk means variability of return, and if that risk is describable
in scope but not in  direction  or  timing  of  movement,  then  timing  becomes
dangerous.  That is because the  variability  of returns may help you as well as
hurt you.  To put this  plainly,  a person  who got out of the market in 1995 or
1996 is still looking for a chance to come back in.

The Asset  Strategy  funds of the  Investment  Trust show a good way to confront
this real risk.  They  offer  various  asset  allocations  which are  attuned to
different risk  tolerances.  And we keep those  allocations for you. You will be
exposed to risk in a way that, hopefully, is tolerable and that exposure will be
there if the risk takes you down, or up.

Sincerely,


Michael J.C. Roth, CFA
President and
Vice Chairman of the Board

Total  return   equals   income  yield  plus  share  price  change  and  assumes
reinvestment of all dividends and capital gain distributions.  No adjustment has
been made for taxes payable by shareholders on their reinvested income dividends
and capital gain  distributions.  The  performance  data quoted  represent  past
performance and are not an indication of future results.  Investment  return and
principal value of an investment will fluctuate,  and an investor's shares, when
redeemed, may be worth more or less than their original cost.

Message from the Managers


[PHOTOGRAPH OF THE FOLLOWING PORTFOLIO MANAGERS APPEARS HERE:
          From L to R: R. David Ullom, CFA (Domestic Stocks), 
        David G. Peebles, CFA (Allocation Manager, Foreign Stocks), 
              Albert C. Sebastian, CFA (Foreign Stocks), and 
               W. Travis Selmier, II, CFA (Foreign Stocks).]


MARKET CONDITIONS
For the fiscal  year ended May 31,  1998,  your Fund's  total  return was 16.29%
which underperformed the Lipper(1) Global Funds Average return of 18.99%.(2) The
European and United States markets have produced excellent returns over the last
twelve  months and  significantly  outperformed  both the  emerging  markets and
Japan.

EUROPE
European  markets  provided  favorable  returns  over the  period  because of an
improved  outlook  for  economic  growth and  continued  corporate  mergers  and
acquisitions.  In  particular,  the  performance  of the banking  and  insurance
sectors  benefited from  acquisitions.  The European markets also appreciated on
news that the European monetary union remained on track.


(1) Refer to page 4 for the Lipper Average definition.
(2) Past  performance  is no  guarantee  of future  results  and the value of 
    your investment may vary according to the Fund's performance.


EMERGING MARKETS
Asia's  economic  problems  have  continued  to cast a pall over  most  emerging
markets,  with early 1998  recoveries  fading by March.  Weaknesses in commodity
prices,  from which many emerging markets'  countries derive  significant export
earnings,  have also taken a toll.  Higher  interest rates on emerging  markets'
debt have raised companies' financing costs. Strength in Mediterranean, selected
Central European,  and South African markets has not been enough to offset these
factors;  therefore,  we have lowered our emerging  markets'  weighting over the
year.

JAPAN
Asia's currency  crisis,  combined with problems within the banking system,  has
continued  to affect the  Japanese  economy and stock  market.  We have begun to
selectively buy quality financial companies while holding export-related stocks.
We have not changed our  underweighted  position  awaiting  more progress on the
restructuring of Japan's tax and financial system.

UNITED STATES
Over  the  six  months  from  November  30,  1997 to May 31,  1998,  the  Fund's
allocation  to U.S.  equities has risen from 25.7% as of November  30, 1997,  to
32.1%  currently.  A wide variety of our domestic  company  stock  holdings have
outperformed the major U.S.  averages,  because they have only minor exposure to
the economic  problems of Southeast  Asia. Such  industries  include  retailing,
financials,  and  healthcare.  Perhaps  surprisingly,  several of our technology
holdings have also  outperformed  the major  averages.  Performance  in domestic
equities  was hampered by  investments  in  household  products,  energy and oil
services, and semiconductors.

OUTLOOK
In the  international  markets we continue to favor European  markets because of
their economic and political stability as well as the relatively strong earnings
growth.  European  equities will also benefit from further economic  integration
and more shareholder  oriented  management.  We remain cautious on Japan pending
further progress on structuring and implementing policies, which would stimulate
economic recovery. Currency volatility and weakness in Asian economies will mean
continued turbulence in emerging markets with select opportunities.  Although we
are  concerned  about a slowdown in earnings  growth in the United  States,  the
fundamentals of the economy are positive and the U.S. market is viewed as a safe
haven.

Independent Auditors' Report

The Shareholders and Board of Trustees

USAA WORLD GROWTH FUND:
We have audited the accompanying statement of assets and liabilities,  including
the portfolio of investments of the USAA World Growth Fund, a series of the USAA
Investment Trust, as of May 31, 1998 and the related statement of operations for
the year then  ended,  the  statements  of changes in net assets for each of the
years in the two-year period then ended, and financial highlights,  presented in
note 8 to the  financial  statements,  for each of the years or  periods  in the
five-year 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  generally   accepted  auditing
standards.  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
securities  owned as of May 31, 1998, 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 present fairly, in all material  respects,  the financial  position of the
USAA World Growth Fund as of May 31, 1998, the results of its operations for the
year then  ended,  the  changes  in its net  assets for each of the years in the
two-year period then ended,  and the financial  highlights for each of the years
or periods in the  five-year  period then ended,  in conformity  with  generally
accepted accounting principles.

USAA WORLD GROWTH FUND
NOTES TO FINANCIAL STATEMENTS

May 31, 1998

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
USAA INVESTMENT TRUST (the Trust),  registered under the Investment  Company Act
of 1940, as amended, is a diversified,  open-end  management  investment company
organized as a Massachusetts business trust consisting of eleven separate funds.
The information  presented in this annual report pertains only to the USAA World
Growth Fund (the Fund). The Fund's investment objective is capital appreciation.
USAA Investment Management Company (the Manager) seeks to achieve this objective
by  investing  at least 65% of the  Fund's  assets in common  stocks,  preferred
stocks and other equity securities of both foreign and domestic issuers.

A.  Security  valuation - The value of each  security is  determined  (as of the
close of  trading  on the New  York  Stock  Exchange  on each  business  day the
Exchange is open) as set forth below:

1.  Portfolio  securities,  except as  otherwise  noted,  traded  primarily on a
domestic  securities  exchange  are  valued  at the  last  sales  price  on that
exchange.  Portfolio securities traded primarily on foreign securities exchanges
are generally  valued at the closing  values of such  securities on the exchange
where primarily traded. If no sale is reported, the average of the bid and asked
prices is generally used depending upon local custom or regulation.

2.  Over-the-counter  securities  are priced at the last sales  price or, if not
available, at the average of the bid and asked prices.

3.  Securities  purchased  with  maturities  of 60 days or less  are  stated  at
amortized cost which approximates market value.

4.  Securities  which cannot be valued by the methods set forth  above,  and all
other assets,  are valued in good faith at fair value,  using methods determined
by the Manager under the general supervision of the Board of Trustees.

B. Federal taxes - The Fund's policy is to comply with the  requirements  of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  substantially all of its income to its shareholders.  Therefore,  no
federal  income or excise  tax  provision  is  required.  As a result of certain
permanent  differences between book and tax basis accounting,  reclassifications
were made to the statement of assets and liabilities at May 31, 1998 to increase
accumulated  undistributed net investment income by $280.3 thousand, to decrease
paid-in  capital by $8.0 thousand and to decrease  accumulated net realized gain
on investments by $272.3 thousand.  A similar  reclassification was made in 1997
to increase accumulated undistributed net investment income by $110.7 thousand.

C.  Investments in securities - Security  transactions  are accounted for on the
date the securities are purchased or sold (trade date).  Gain or loss from sales
of investment  securities  is computed on the  identified  cost basis.  Dividend
income,  less foreign taxes, if any, is recorded on the ex-dividend date. If the
ex-dividend  date has passed,  certain  dividends  from foreign  securities  are
recorded upon  notification.  Interest  income is recorded on the accrual basis.
Discounts and premiums on short-term  securities  are amortized over the life of
the respective securities.

D. Foreign currency translations - The assets of the Fund may be invested in the
securities  of foreign  issuers.  Since the  accounting  records of the Fund are
maintained in U.S.  dollars,  foreign  currency amounts are translated into U.S.
dollars on the following basis:

1. Market value of securities, other assets, and liabilities at the mean between
the bid and asked translation rates of such currencies against U.S. dollars on a
daily basis.

2.  Purchases  and sales of  securities,  income,  and  expenses  at the rate of
exchange obtained from an independent pricing service on the respective dates of
such transactions.

Net realized and unrealized foreign currency  gains/losses  occurring during the
holding  period  of  investments  are  a  component  of  realized  gain/loss  on
investments   and   unrealized    appreciation/depreciation    on   investments,
respectively.

Net realized foreign currency gains/losses arise from sales of foreign currency,
currency  gains/losses  realized  between  the  trade  and  settlement  dates on
security  transactions,  and from the difference  between  amounts of dividends,
interest,  and foreign  withholding  taxes  recorded on the Fund's books and the
U.S. dollar  equivalent of the amounts  received.  Net realized foreign currency
gains/losses have been  reclassified from accumulated net realized  gain/loss to
accumulated  undistributed  net investment income on the statement of assets and
liabilities  as  such  amounts  are  treated  as  ordinary  income/loss  for tax
purposes.  Net unrealized  foreign  currency  exchange  gains/losses  arise from
changes  in the  value of assets  and  liabilities  other  than  investments  in
securities resulting from changes in the exchange rate.

E. Use of estimates - The preparation of financial statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and  assumptions   that  may  affect  the  reported  amounts  in  the  financial
statements.

(2) LINES OF CREDIT
The Fund  participates  with other USAA funds in two joint short-term  revolving
loan  agreements  totaling  $850  million,  one with  USAA  Capital  Corporation
(CAPCO),  an affiliate of the Manager ($750 million  uncommitted),  and one with
NationsBank  of  Texas,  N.A.  ($100  million  committed).  The  purpose  of the
agreements is to meet  temporary or emergency cash needs,  including  redemption
requests that might  otherwise  require the untimely  disposition of securities.
Subject to availability under its agreement with CAPCO, the Fund may borrow from
CAPCO an amount up to 5% of the Fund's  total assets at CAPCO's  borrowing  rate
with no markup.  Subject to availability  under its agreement with  NationsBank,
the Fund may borrow from NationsBank an amount which,  when added to outstanding
borrowings  under the CAPCO  agreement,  does not exceed 25% of the Fund's total
assets at NationsBank's borrowing rate plus a markup. The Fund had no borrowings
under either of these agreements during the year ended May 31, 1998.

(3) DISTRIBUTIONS
Distributions  of  net  investment  income  and  realized  gains  from  security
transactions not offset by capital losses are made in the succeeding fiscal year
or as otherwise required to avoid the payment of federal taxes.

(4) INVESTMENT TRANSACTIONS
Cost of purchases and proceeds from sales of  securities,  excluding  short-term
securities,  for the year  ended May 31,  1998 were  $144.7  million  and $147.0
million, respectively.

Gross  unrealized  appreciation  and depreciation of investments at May 31, 1998
was $117.8 million and $17.3 million, respectively.

(5) FOREIGN CURRENCY CONTRACTS
A forward currency contract  (currency  contract) is a commitment to purchase or
sell a foreign  currency at a specified  date, at a negotiated  price.  The Fund
currently enters into currency contracts only in connection with the purchase or
sale of a security denominated in a foreign currency.  These contracts allow the
Fund to "lock in" the U.S. dollar price of the security.  Currency contracts are
valued on a daily basis using foreign  currency  exchange rates obtained from an
independent  pricing service.  Risks of entering into currency contracts include
the potential  inability of the  counterparty  to meet the terms of the contract
and the Fund giving up the opportunity for potential profit.
