ITEM 1. REPORTS TO STOCKHOLDERS.

FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Trust, you incur ongoing costs, including
management fees; service fees and other Trust expenses. These examples are
intended to help you understand your ongoing costs (in dollars) of investing in
the Trust and to compare these costs with the ongoing costs of investing in
other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended December 31, 2005.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line together with the amount you invested, to estimate the expense that you
paid over the period. Simply divide your account value by $1,000.00 (for
example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply
the result by the number in the "actual" line under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Trust's actual expense ratio, and an assumed rate of
return of 5% per year before expenses, which is not the Trust'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 Trust and
other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Trust's annualized expense ratio, multiplied by the
average account value over the period, multiplied by 184/365 (to reflect the
one-half year period). The annualized expense ratio based on the 6-month period
ended December 31, 2005 is as follows:

NOTES TO FINANCIAL STATEMENTS  Unaudited

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

Centennial Tax Exempt Trust (the Trust) is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Trust's investment objective is to seek the maximum short-term interest
income exempt from federal income taxes that is consistent with low capital risk
and the maintenance of liquidity. The Trust's investment advisor is Centennial
Asset Management Corporation (the Manager), a subsidiary of OppenheimerFunds,
Inc. (OFI).

      The following is a summary of significant accounting policies consistently
followed by the Trust.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The net asset value of shares of the Trust is normally
determined twice each day, at 12:00 Noon Eastern time and at 4:00 P.M. Eastern
time on each day the New York Stock Exchange (the Exchange) is open for trading.
Portfolio securities are valued on the basis of amortized cost, which
approximates market value.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Trust intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income, including any net
realized gain on investments not offset by capital loss carryforwards, if any,
to shareholders, therefore, no federal income or excise tax provision is
required.

      Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Trust.

      The estimated capital loss carryforward represents carryforward as of the
end of the last fiscal year, increased for losses deferred under tax accounting
rules to the current fiscal year and is increased or decreased by capital losses
or gains realized in the first six months of the current fiscal year. During the
six months ended December 31, 2005, it is estimated that the Trust will utilize
$5,544 of capital loss carryforward to offset realized capital gains. During the
year ended June 30, 2005, the Trust utilized $96,274 of capital loss
carryforward to offset realized capital gains.

As of June 30, 2005, the Trust had available for federal income tax purposes
unused capital loss carryforward as follows:

                          EXPIRING
                          ---------------------------
                          2012                 $5,544
                          ---------------------------

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a deferred
compensation plan for independent trustees that enables trustees to elect to
defer receipt of all or a portion of the annual compensation they are entitled
to receive from the Trust. For purposes of determining the amount owed to the
Trustee under the plan, deferred amounts are


                        22 | CENTENNIAL TAX EXEMPT TRUST


treated as though equal dollar amounts had been invested in shares of the Trust
or in other Oppenheimer funds selected by the Trustee. The Trust purchases
shares of the funds selected for deferral by the Trustee in amounts equal to his
or her deemed investment, resulting in a Trust asset equal to the deferred
compensation liability. Such assets are included as a component of "Other"
within the asset section of the Statement of Assets and Liabilities. Deferral of
trustees' fees under the plan will not affect the net assets of the Trust, and
will not materially affect the Trust's assets, liabilities or net investment
income per share. Amounts will be deferred until distributed in accordance to
the Plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income distributions, if any, are declared
daily and paid monthly. Capital gain distributions, if any, are declared and
paid annually but may be paid at other times to maintain the net asset value per
share at $1.00.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. Custodian Fees and Expenses in the Statement of Operations may
include interest expense incurred by the Trust on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Trust pays
interest to its custodian on such cash overdrafts to the extent they are not
offset by positive cash balances maintained by the Trust. The Reduction to
Custodian Expenses line item, if applicable, represents earnings on cash
balances maintained by the Trust during the period. Such interest expense and
other custodian fees may be paid with these earnings.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. generally
accepted accounting principles 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 income and expenses during the reporting
period. Actual results could differ from those estimates.

2. SHARES OF BENEFICIAL INTEREST

The Trust has authorized an unlimited number of no par value shares of
beneficial interest. Transactions in shares of beneficial interest were as
follows:



                             SIX MONTHS ENDED DECEMBER 31, 2005                YEAR ENDED JUNE 30, 2005

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

investment advisory agreement with the Trust which provides for a fee at an
annual rate of 0.50% of the first $250 million of the Trust's net assets, 0.475%
of the next $250 million, 0.45% of the next $250 million, 0.425% of the next

- --------------------------------------------------------------------------------
ADMINISTRATION SERVICE FEES. The Trust pays the Manager a fee of $1,500 per year
for preparing and filing the Trust's tax returns.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. Shareholder Services, Inc. (SSI) acts as the transfer and

companies. The Trust pays SSI a per account fee. For the six months ended
December 31, 2005, the Trust paid $250,840 to SSI for services to the Trust.

- --------------------------------------------------------------------------------
SERVICE PLAN (12B-1) FEES. The Trust has adopted a service plan. It reimburses
Centennial Asset Management Corporation, the Distributor, for a portion of its
costs incurred for services provided to accounts that hold shares of the Trust.
Reimbursement is made periodically depending on asset size, at an annual rate of
up to 0.20% of the average annual net assets of the Trust. The Distributor
currently uses all of those fees to pay dealers, brokers, banks and other
financial institutions periodically for providing personal services and
maintenance of accounts of their customers that hold shares of the Trust. Fees
incurred by the Trust under the Plan are detailed in the Statement of
Operations.

- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. Under the investment advisory agreement,
when the value of the Trust's net assets is less than $1.5 billion, the annual
fee payable to the Manager shall be reduced by $100,000 based on average net
assets computed daily and paid monthly at the annual rates. However, the annual
fee cannot be less than $0.

      SSI has voluntarily agreed to limit transfer and shareholder servicing
agent fees to 0.35% of average annual net assets of the Trust. This undertaking
may be amended or withdrawn at any time.

                        25 | CENTENNIAL TAX EXEMPT TRUST


BOARD APPROVAL OF THE TRUST'S INVESTMENT
ADVISORY AGREEMENT  Unaudited

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Trust's
investment advisory agreement (the "Agreement"). The Investment Company Act of
1940, as amended, requires that the Board request and evaluate, and that the
Manager provide, such information as may be reasonably necessary to evaluate the
terms of the Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information, that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Trust services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Trust and the
Manager, (iii) the fees and expenses of the Trust, including comparative expense
information, (iv) the profitability of the Manager, including an analysis of the
cost of providing services, (v) whether economies of scale are realized as the
Trust grows and whether fee levels reflect these economies of scale for Trust
investors and (vi) other benefits to the Manager from its relationship with the
Trust. Outlined below is a summary of the principal information considered by
the Board as well as the Board's conclusions.

      NATURE, QUALITY, AND EXTENT OF SERVICES. The Board considered information
on the nature and extent of the services provided to the Trust by the Manager
and by OppenheimerFunds, Inc., the Manager's parent company, and information
regarding the key personnel that provide such services. The Manager's duties
include providing the Trust with the services of the portfolio manager and the
Manager's investment team, who provide research, analysis and other advisory
services in regard to the Trust's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Trust policies and procedures and adherence to the Trust's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Trust as well. Those services include providing and supervising
all administrative and clerical personnel that are necessary in order to provide
effective corporate administration for the Trust; compiling and maintaining
records with respect to the Trust's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Trust for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Trust's
shares. The Manager also provides the Trust with office space, facilities and
equipment.

      The Board also considered the quality of the services provided and the
quality of the Manager's resources that are available to the Trust. The Board
took account of the fact that


                        26 | CENTENNIAL TAX EXEMPT TRUST


the Manager has been an investment advisor since 1978 and that the Manager's and
its parent's assets under management rank among the top mutual fund managers in
the United States. The Board evaluated the Manager's administrative, accounting,
legal and compliance services, and information the Board has received regarding
the experience and professional qualifications of the Manager's key personnel
and the size and functions of its staff providing investment management services
to the Trust. The Board also considered compliance reports from the Trust's
Chief Compliance Officer. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of John
Bonnell and the Manager's money market investment team and analysts. Mr. Bonnell
has had over 17 years of experience managing money market, equity, fixed income
and municipal/tax-exempt investments. The Board members also considered the
totality of their experiences with the Manager, as directors or trustees of the
Trust and other funds advised by the Manager. In light of the foregoing, the
Board concluded that the Trust benefits from the services provided under the
Agreement as a result of the Manager's experience, reputation, personnel,
operations, and resources.

      INVESTMENT PERFORMANCE OF THE TRUST. During the year, the Manager provided
information on the performance of the Trust at each Board meeting, including
comparative performance information. The Board also reviewed information,
prepared by the Manager and by the independent consultant, comparing the Trust's
historical performance to relevant market indices and to the performance of
other tax-exempt money market funds. The Board noted that the Trust's one-year
performance was slightly better than its peer group median. However its
three-year, five-year and ten-year performance were below its peer group median.

      COSTS OF SERVICES AND PROFITS REALIZED BY THE MANAGER. The Board
considered information regarding the Manager's costs in serving as the Trust's
investment adviser, including the costs associated with the personnel and
systems necessary to manage the Trust, and information regarding the Manager's
profitability from its relationship with the Trust. The Board reviewed the fees
paid to the Manager and the other expenses borne by the Trust. The Board also
evaluated the comparability of the fees charged and the services provided to the
Trust to the fees and services for other clients or accounts advised by the
Manager. The independent consultant provided comparative data in regard to the
fees and expenses of the Trust, other tax-exempt money market funds and other
funds with comparable asset levels and distribution features. Under the
Agreement, when the value of the Trust's net assets is less than $1.5 billion,
the annual fee payable to the Manager shall be reduced by $100,000 based on
average net assets computed daily and paid monthly at the annual rates, however,
the annual fee cannot be less than $0. The Board noted that the Trust's actual


                        27 | CENTENNIAL TAX EXEMPT TRUST


BOARD APPROVAL OF THE TRUST'S INVESTMENT
ADVISORY AGREEMENT  Unaudited / Continued

management fees are lower than its peer group median but higher than its peer
group average, however, its contractual management fees and total expenses are
both lower than its peer group median and average. In light of this, the Board
concluded that the management fee was reasonable.

      ECONOMIES OF SCALE. The Board considered whether the Manager may realize
economies of scale in managing and supporting the Trust, whether those economies
of scale benefit the Trust's shareholders and the current level of Trust assets
in relation to the Trust's management fee breakpoints, which are intended to
share with shareholders economies of scale that may exist as the Trust grows.

      OTHER BENEFITS TO THE MANAGER. In addition to considering the profits
realized by the Manager, the Board considered information that was provided
regarding the direct and indirect benefits the Manager receives as a result of
its relationship with the Trust, including compensation paid to the Manager's
affiliates. The Board also considered the nature and quality of services
provided by affiliates of the Manager, which it reviews at other times during
the year in connection with the renewal of the Trust's service agreements. The
Board considered that the Manager must be able to pay and retain experienced
professional personnel at competitive rates to provide services to the Trust and
that maintaining the financial viability of the Manager is important in order
for the Manager to continue to provide significant services to the Trust and its
shareholders.

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Trust and to the independent Trustees. Trust counsel and the independent
Trustees' counsel are both independent of the Manager within the meaning and
intent of the Securities and Exchange Commission Rules.

      Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
decided to continue the advisory agreement for another year. In arriving at this
decision, the Board did not single out any factor or factors as being more
important than others, but considered all of the factors together. The Board
judged the terms and conditions of the advisory agreement, including the
management fee, in light of all of the surrounding circumstances.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance Committee (the "Committee") will evaluate potential
      Board candidates to assess their qualifications. The Committee shall have
      the authority, upon approval of the Board, to retain an executive search
      firm to assist in this effort. The Committee may consider recommendations
      by business and personal contacts of current Board members and by
      executive search firms which the Committee may engage from time to time
      and may also consider shareholder recommendations. The Committee may
      consider the advice and recommendation of the Funds' investment manager
      and its affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's background, skills, and
      experience; whether the individual is an "interested person" as



      defined in the Investment Company Act of 1940; and whether the individual
      would be deemed an "audit committee financial expert" within the meaning
      of applicable SEC rules. The Committee also considers whether the
      individual's background, skills, and experience will complement the
      background, skills, and experience of other nominees and will contribute
      to the Board. There are no differences in the manner in which the
      Committee evaluates nominees for trustees based on whether the nominee is
      recommended by a shareholder.

3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where required, to
      shareholders. Recommendations for trustee nominees should, at a minimum,
      be accompanied by the following:

      o     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;

      o     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      o     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      o     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.
