                            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 Funds.

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:

                       MESSAGE FROM THE PRESIDENT

We recently received a bit of good news.

It is that all eight of the tax-exempt bond funds which we offer, the Long-Term,
Intermediate-Term and Short-Term Funds, plus our five state-specific bond funds,
have been awarded five-star ratings by Morningstar for the one-year period ended
September 30,  1997.* We are pleased with this  achievement,  mainly  because of
what it confirms. To understand that, let's talk about what these ratings mean.


<TABLE>



                           EIGHT IS GREAT!

                  USAA's eight Tax-Exempt Bond Funds
               all receive Morningstar's 5 star rating
   in the municipal bond funds category for the year ended 9-30-97.*

Total Funds rated:                          1,760     1,374         668        326


</TABLE>



Past performance is no guarantee of future results.
* Morningstar proprietary ratings reflect historical  risk-adjusted  performance
through 9/30/97. The ratings are subject to change monthly.  Morningstar ratings
are calculated  from the Fund's 3-, 5-, and 10-year average annual total returns
(with fee  adjustments)  in excess of 90-day  Treasury bill returns,  and a risk
factor that reflects fund performance below 90-day Treasury bill returns.  There
is a three-year  minimum  performance  requirement  before a fund is rated.  The
one-year rating is calculated using the same methodology, but is not a component
of the overall rating.  Overall rating is a weighted average of a fund's 3-, 5-,
and 10-year ratings, when applicable. Among 1,374 municipal bond funds, the USAA
Tax Exempt  Intermediate-Term,  Short-Term,  Texas Tax-Free Income, and Virginia
Bond Funds received overall ratings of 5 stars.  The USAA Tax Exempt  Long-Term,
California  Bond,  New York Bond,  and Florida  Tax-Free  Income Funds  received
overall  ratings  of 4  stars.  The top ten  percent  of the  funds  in a rating
category receive five stars and the next 22.5% receive four stars.

** These funds are only available for residents in these states.

(PHOTO OF THE PRESIDENT, MICHAEL J. C. ROTH, APPEARS HERE)

There are some standard words which you will see commonly  published  along with
any reference to  Morningstar  ratings.  They are what we call a legend and they
include this; "Morningstar  proprietary ratings reflect historical risk-adjusted
performance  through  [date].  The ratings are subject to change  monthly..." At
many conferences I have attended, I have heard Morningstar  executives emphasize
the  point  that  their  ratings  are  historically  based and that they are not
predictive.  In other words they tell you who did well,  but they do not purport
to tell you who will do well.

Having said all that,  we are pleased  with these  ratings  because  they are an
affirmation of one of our basic beliefs. We believe investors in tax-exempt bond
funds want,  and will benefit most from  tax-exempt  income.  That seems obvious
when you put it on paper,  but it is  something  which is easily  obscured.  The
performance  and the relative  ratings of these funds are based upon their total
returns,  which means both interest income and price change. We have chosen very
deliberately to manage our funds for  consistently  high yields,  and we believe
that over time this will be beneficial to our investors  both in terms of income
and total return.  The Morningstar  ratings  indicate that in the recent past we
have been correct in these beliefs.

And besides, it's nice to have someone say you're "five-star."

Sincerely,

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

The broad-based  Lehman Brothers Municipal Bond Index is an unmanaged index that
tracks total return  performance for the long-term  investment  grade tax-exempt
bond  market.  The Lipper  Texas  Municipal  Debt Funds  Average is the  average
performance  level of all Texas  Municipal  Debt  Funds,  as  computed by Lipper
Analytical Services,  an independent  organization that monitors the performance
of mutual funds.  All tax-exempt bond funds will find it difficult to outperform
the Lehman Index, since funds have expenses.



                            MESSAGE FROM THE MANAGER

A Remarkable Economy
The Federal  Reserve  Board (the Fed) has made it quite  evident  that they will
tolerate a robust  economy and low  unemployment.  After all, Fed Chairman  Alan
Greenspan  himself  described  the economy's  performance  as  remarkable.  Such
tolerance is unusual for the Fed since in the past prolonged economic growth and
tight labor markets  raised  serious  concerns of inflation.  However,  Chairman
Greenspan  has made it crystal  clear that, if inflation  should  re-ignite,  he
would act  forcefully.  Very likely the Fed would initiate one or more increases
in short-term  interest  rates  triggering a negative  reaction by the financial
markets.  Obviously,  new economic conditions and relationships have lowered the
inflationary threshold compared to the 1980s. But, a limit still exists. It will
be most  interesting  to see how long and how far this  economy  can go  without
generating inflationary pressures.

Interest Rates
The yield on the Bond Buyer 40-Bond Index (BBI40), the industry standard for the
yield of long-term,  investment-grade  municipal bonds,  fell nearly 1/2 percent
from March 31, 1997, until July. During August and September the BBI40 traded in
the range of 5.40% to 5.60%.

Portfolio Strategy
I focus  primarily on  generating  maximum  tax-exempt  income that  potentially
should  produce  the best  after-tax  total  return  over a 3-5 year  investment
horizon.  I do not buy exotic  derivatives  or bonds subject to the  alternative
minimum tax (AMT), nor do I hedge the portfolio with futures contracts.

Absolute  concentration on pretax total return implies that the manager believes
he or she  can  forecast  interest  rates.  I  don't  believe  anyone  has  ever
demonstrated  that they can  consistently  predict the future of interest rates.
Although I pay close  attention to total return,  my primary  concern remains on
generating  tax-free  income.  There are other reasons.  Typically income is the
largest  component  of  total  return,  and  over  longer  time  horizons  price
volatility tends to even out.

Current Market Conditions
With interest rates nearing  four-year lows,  finding a value in the marketplace
is more of a challenge.  Currently,  investment grade bonds, regardless of their
credit rating (AAA or BBB),  are selling at yields within a very narrow range. I
will  invest  only in those  bonds  that I  believe  offer  the best  value  for
shareholders.

Your Fund's Performance
Since long-term interest rates dropped during the period,  your Fund's net asset
value  (NAV) per share  increased  by $.47 to $10.85,  or 4.5%,  since March 31,
1997. The Fund's  performance  compared  favorably to its peer group. While past
performance is no guarantee of future results,  the Fund's  annualized  dividend
yield(1)  for the past six months was 5.32%,  as  compared  to the Lipper  Texas
Municipal  Debt Funds  average of 4.80% for the 20 funds in the  category.(2)For
the same  period,  the Fund's  total  return(3)  was 7.89%,  as  compared to the
Lipper's average of 6.31%.

A chart in the form of a bar graph appears here  illustrating the comparison of
the 12 Month  Dividend  Yield of the USAA Texas  Tax-Free  Income Fund and
the Lipper  Texas  Municipal  Debt Funds  Average from 9/30/95 to 9/30/97.

The Lipper Texas  Municipal Debt Funds Average is computed by Lipper  Analytical
Services,  an independent  organization  that monitors the performance of mutual
funds.  12-month  dividend yield is computed by dividing  income  dividends paid
during the previous 12 months by the latest  month-end net asset value  adjusted
for capital  gains  distributions.  The graph  represents  data from  9/30/95 to
9/30/97.


(1) Dividend  yield is  computed by dividing  income  dividends  paid during the
    previous 6 months by the latest month-end net asset value adjusted for 
    capital gains distributions and annualizing the result.
(2) Lipper  Analytical  Services is an independent  organization that monitors 
    the performance of mutual funds.
(3) Total  return  equals  income  return  plus share  price  change and assumes
    reinvestment of dividends and capital gains distributions.

The State of Texas
The Texas  economy  continues to diversify  and now more closely  resembles  the
national economy as compared to the 1970s and 1980s. Growth in the state's gross
domestic  product  (GDP),  particularly  in services,  high tech,  exports,  and
manufacturing, outpaced the nation for the last two years. Texas ranks second in
the  nation in total  export  trade  thanks in part to NAFTA.(4) Personal income
growth has exceeded the nation's  since 1989,  but still remains only 91% of the
national average and ranks 32nd.

Property  values  have now  increased  for  three  consecutive  years  following
declines that  stretched  back to the mid 1980s.  In fact,  construction  is the
fastest growing industry sector. State GDP growth may begin to slow as evidenced
by the deceleration of retail sales in 1996. Since Texas has nearly the youngest
median age in the nation, legislators decided to target 60% of incremental state
revenues  for public and higher  education.  After a very  exciting  legislative
session,  Governor Bush's property tax reform was defeated.  Looking forward, we
will closely  monitor  financial and legislative  issues that could  potentially
impact your Fund's holdings.

                            MESSAGE FROM THE MANAGER

The Market
All financial  markets are driven by supply and demand  relationships.  This was
especially  highlighted  in the summer  months by the  tax-exempt  money market.
During the six months  ending  September  30, 1997,  the one-year  Treasury bill
yield ranged from 6.07% to 5.42% and has generally trended down since the end of
April. The same cannot be said for one-year  municipal notes. As measured by the
Bond Buyer  One-Year Note Index,(1) yields ranged from 3.97% to 3.76% during the
same time span,  and ended the  period at 3.82%,  only  slightly  lower than the
3.85%  at the  end  of  March.  Why  didn't  short-term  municipals  follow  the
short-term  treasury market closer?  The municipal  market is influenced more by
the amount of securities  available in the market,  and the amount of cash to be
invested. Several possible factors that combined this year to influence both the
supply  of  and  demand  for  short-term   tax-exempt  securities  included  the
following:

      -  The scarcity in supply of one-year notes.
      -  Borrowings made for periods longer than twelve months.
      -  An increase in the alternative to fixed rate notes.

With improved economic  conditions  issuers did not need to borrow as much as in
prior  years.  In  fact,  more  issuers  chose to  borrow  for  fifteen  months,
temporarily  making  their  securities  too long for money  market  investments.
Alternatively, underwriters created money market eligible variable rate products
out of  long-term  securities,  thus  increasing  the  supply of  variable  rate
securities.(2)


(1) Bond Buyer Index is the  industry  standard  for yields of  investment-grade
    municipal bonds.
(2) Variable rate demand note: A note  representing  borrowings that is payable
    on demand and that bears interest tied to money market rate.


The equity and long-term bond markets both  experienced  tremendous  price gains
over the last six months.  This was accompanied by extreme volatility which many
expect caused large cash flows into and out of money market funds.  In addition,
during the Federal  government  budget  negotiations  one  proposal  contained a
provision that would reduce the amount of tax-exempt interest corporations could
claim.  This  provision was not included in the final budget bill, but many feel
corporations  reduced their municipal  holdings (a large amount being short-term
securities)  temporarily,  only to buy into the  market  after  the  budget  was
passed.  These events combined to influence the demand for short-term  municipal
securities.  Situations such as these, which are unique to the municipal market,
explain why the municipal  market does not always  closely track the much larger
and highly efficient treasury market.

Strategy
Your Fund strives to meet its objective in any  prevailing  market  environment.
This is done in part by maintaining a mix of fixed rate  securities and variable
rate  securities  in the  fund.  Fixed  rate  securities  lock in rates and help
stabilize  the Fund's  yield  during the periods when there is a large amount of
money in the  market  relative  to  supply.  Variable  rate  securities  provide
liquidity   necessary  to  take  advantage  of  higher  yielding  securities  as
opportunities  arise. Our longstanding  commitment to credit research is a major
factor that ensures all purchases  are the best relative  value in the market at
any given time.

Performance
While past  performance  is no  guarantee of future  results,  for the 12 months
ending  September  30,  1997,  your  Fund  ranked  8 out of 149  State  Specific
Tax-Exempt Money Market Funds according to IBC Financial Data, Inc. with a yield
of 3.36%. The average for the category over the same time period was 3.00%.

Texas
The Texas economy  continues to expand and  diversify.  While the rate of growth
has  tempered  (2.8% for 1996 vs. 3.5% in 1995) it still  exceeds  the  national
rate.  The Texas economy as measured by its gross state product  accounts for 7%
of the total U.S. economy. Exports (especially to Mexico) continue to be a major
factor in the Texas economy, increasing 248% over the last ten years.

One of the key issues debated during the most recent legislative session was an
attempt  to lower  school  property  taxes.  While both the Senate and the House
passed versions of the bill, a compromise was not reached.  As a result,  it was
agreed to use the state's $1 billion  surplus in the  current  budget to provide
school property tax relief to homeowners by increasing the homestead  exemption.
Even  though  the state  continues  to show  strong  financial  performance,  we
continue to analyze each issue on a case-by-case basis and remain very selective
when investing Fund assets.

Fixed-Rate  Instruments  -- consist of municipal  bonds,  notes,  and commercial
paper. The interest rate is constant to maturity.  Prior to maturity,  the price
of a  fixed-rate  instrument  generally  varies  inversely  to the  movement  of
interest rates.

Put Bonds -- provide the right to sell the bond at face value at specific tender
dates prior to final maturity.  The put feature shortens the effective  maturity
to the next tender date.

Variable Rate Demand Notes (VRDN) -- provide the right,  on any business day, to
sell the  security  at face  value on  either  that  day or in seven  days.  The
interest rate is adjusted at a stipulated daily,  weekly, or monthly interval to
a rate that reflects  current  market  conditions.  In money market  funds,  the
effective  maturity is the date on which the underlying  principal amount may be
recovered  or  the  next  rate   adjustment   date  consistent  with  regulatory
requirements.  In bond funds, the effective  maturity is the next put date. Most
VRDNs possess a credit enhancement.

Credit  Enhancement (CRE) -- adds the financial  strength of the provider of the
enhancement to support the issuer's ability to repay the principal when due. The
enhancement may be provided by either a high quality bank, insurance company, or
other  corporation,  or a  collateral  trust.  Typically,  the  rating  agencies
evaluate  the  security  based upon the credit  standing of the  provider of the
credit enhancement, rather than the credit standing of the issuer.

Notes to Financial Statements


September 30, 1997
(Unaudited)


(1)   Summary of Significant Accounting Policies
USAA State Tax-Free Trust (the Trust),  registered under the Investment  Company
Act of 1940,  as  amended,  is a  diversified,  open-end  management  investment
company  organized as a Delaware  business  trust  consisting  of four  separate
funds. The information  presented in this semiannual report pertains only to the
Texas Tax-Free Income Fund and Texas Tax-Free Money Market Fund (the Funds). The
Funds have a common  objective of providing Texas investors with a high level of
current  interest  income that is exempt from federal  income  taxes.  The Texas
Tax-Free  Money Market Fund has a further  objective of  preserving  capital and
maintaining liquidity.

A.  Security  valuation --  Investments  in the Texas  Tax-Free  Income Fund are
valued each  business  day by a pricing  service (the  Service)  approved by the
Trust's  Board of Trustees.  The Service  uses the mean  between  quoted bid and
asked prices or the last sale price to price  securities  when, in the Service's
judgement,  these prices are readily  available  and are  representative  of the
securities'  market  values.  For many  securities,  such prices are not readily
available.  The Service generally prices these securities based on methods which
include  consideration of yields or prices of municipal securities of comparable
quality,  coupon,  maturity and type,  indications  as to values from dealers in
securities,  and general market  conditions.  Securities which are not valued by
the Service,  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.  Securities purchased with maturities of 60 days or less and, pursuant
to Rule 2a-7 of the Investment  Company Act of 1940, as amended,  all securities
in the Texas  Tax-Free  Money  Market Fund,  are stated at amortized  cost which
approximates market value.

B. Federal taxes -- Each 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.

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.  Interest
income is recorded  daily on the accrual  basis.  Premiums  and  original  issue
discounts  are  amortized  over the life of the  respective  securities.  Market
discounts are not amortized.  Any ordinary income related to market discounts is
recognized  upon  disposition of the  securities.  The Funds  concentrate  their
investments in Texas  municipal  securities and therefore may be exposed to more
credit risk than portfolios with a broader geographical diversification.

D. 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 Funds  participate 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,  each Fund may borrow
from CAPCO an amount up to 5% of its total assets at CAPCO's borrowing rate with
no markup.  Subject to availability  under its agreement with NationsBank,  each
Fund may borrow from  NationsBank  an amount  which,  when added to  outstanding
borrowings under the CAPCO agreement, does not exceed 15% of its total assets at
NationsBank's  borrowing rate plus a markup.  The Funds had no borrowings  under
either of these agreements during the six-month period ended September 30, 1997.

(3)   Distributions
Net  investment  income  is  accrued  daily  as  dividends  and  distributed  to
shareholders  monthly.  All net investment income available for distribution was
distributed at September 30, 1997.

Distributions of 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
Purchases and sales/maturities of securities,  excluding short-term  securities,
for the six-month  period ended September 30, 1997 for the Texas Tax-Free Income
Fund   were   $6,627,591   and   $3,618,909,    respectively.    Purchases   and
sales/maturities of securities for the six-month period ended September 30, 1997
for the Texas  Tax-Free  Money  Market  Fund  were  $8,326,429  and  $8,320,000,
respectively.

Gross  unrealized  appreciation and depreciation of investments at September 30,
1997 for the Texas Tax-Free Income Fund was $824,494 and $2,302, respectively.

(5)   Transactions with Manager
A. Management fees -- The investment policies of the Funds and the management of
the Funds' portfolios are carried out by USAA Investment Management Company (the
Manager).  Management fees are computed as a percentage of aggregate average net
assets (ANA) of both Funds  combined,  which on an annual basis is equal to .50%
of the first  $50,000,000,  .40% of that portion over  $50,000,000  but not over
$100,000,000,  and  .30% of that  portion  over  $100,000,000.  These  fees  are
allocated on a proportional basis to each Fund monthly based upon ANA.

The Manager has voluntarily  agreed to limit the annual expenses of each Fund to
 .50% of its average net assets through August 1, 1998.

B. Transfer agent's fees -- USAA Transfer Agency Company, d/b/a USAA Shareholder
Account Services, an affiliate of the Manager,  provides transfer agent services
to the Funds  based on an  annual  charge of $26 per  shareholder  account  plus
out-of-pocket expenses.

C.  Underwriting  services -- The Manager  provides  exclusive  underwriting and
distribution  of the Funds'  shares on a  continuing  best  efforts  basis.  The
Manager receives no commissions or fees for this service.

(6)   Transactions with Affiliates
Certain trustees and officers of the Funds are also directors,  officers, and/or
employees  of the  Manager.  None of the  affiliated  trustees or Fund  officers
received any compensation from the Funds.
