INDEPENDENT AUDITORS' REPORT
----------------------------

Savings and Investment Plan Committee
Analysts International Corporation
Minneapolis, Minnesota


We have audited the accompanying statements of net assets available for plan
benefits of Analysts International Corporation Savings and Investment Plan (the
Plan) as of June 30, 1997 and 1996 and the related statements of changes in net
assets available for plan benefits for the years then ended.  These financial
statements are the responsibility of the Plan's management.  Our responsibility
is to express an opinion on these financial statements 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 are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  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, such financial statements present fairly, in all material
respects, the net assets available for plan benefits as of June 30, 1997 and
1996 and the changes in net assets available for plan benefits for the years
then ended in conformity with generally accepted accounting principles.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental information by fund for
the years ended June 30, 1997 and 1996, the supplemental schedules of Assets
Held for Investment Purposes as of June 30, 1997 and Reportable Transactions for
the year ended June 30, 1997 are presented for purposes of additional analysis
of the basic financial statements and for complying with the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974 and are not a required part of the basic
financial statements.  This supplemental information is the responsibility of
the Plan's management.  The supplemental information and schedules have been
subjected to the auditing procedures applied in the audit of the basic financial
statements and, in our opinion, are fairly stated in all material respects in
relation to the basic financial statements taken as a whole.

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


A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Investments are stated at market value using primarily quoted market values.
Promissory notes from participants are stated at the outstanding principal
balance.

The financial statements have been prepared on the accrual basis of accounting.
All security transactions are recorded on their trade date.

Participants have control over the allocation of their account balances among
each of the eight Putnam Funds.  However, because Analysts International
Corporation (AiC) designates the investment option for the employer matching
contributions in the AiC Common Stock Fund, participants do not have complete
control of their assets invested in this fund.


B.  THE PLAN:

The Plan was established January 1, 1985 under Section 401(k) of the Internal
Revenue Code for the purpose of providing retirement and other benefits to
eligible participants.  An employee of AiC becomes eligible for the Plan upon
commencement of active service.

The Plan is funded primarily by employee contributions.  Eligible employees may
contribute up to 15% of their gross annual wages for pre-tax saving
contributions.  In addition, the Plan allows rollover contributions from certain
qualified retirement plans.

Plan participants may choose to have their share of the Plan funds invested in
one or more of eight investment funds offered by the Putnam Companies and/or the
AiC Common Stock Fund.  The eight Putnam funds include the Putnam Money Market
Fund, the Putnam U.S. Government Income Trust, the Putnam High Yield Trust, the
Putnam Fund for Growth and Income, the Putnam Voyager Fund, the Putnam Global
Growth Fund, the Putnam OTC Emerging Growth Fund and the Putnam International
Growth Fund.  Effective May 1, 1997 the Plan was amended adding the Putnam
International Growth Fund.  A participant's account (consisting of employee
contributions and investment income) is fully vested.

                                          6


Participant loans are made in compliance with federal regulations in effect at
the time of the loan.  Participant loans outstanding, included in investments,
amounted to $1,040,222 at June 30, 1997 and $990,216 at June 30, 1996.

The Plan provides for employer matching contributions where the employer matches
18% of the employee's pre-tax saving contributions, provided the employee has
been employed by the employer for one year or more and is not a highly
compensated employee as defined by federal tax laws.  The employer matching
contributions are invested in the AiC Common Stock Fund.

A participant's interest in the employer matching contribution vests at the rate
of 20% per year after three years of service with 100% vesting after seven
years.  Any nonvested portion of employer matching contributions to the accounts
of participants who withdraw from the Plan are forfeited and used by the
employer to reduce future matching contributions.

Although the Company has not expressed an intent to discontinue the Plan, it may
do so at any time, subject to provisions set forth in the Employee Retirement
Income Security Act of 1974.  If the Plan is terminated, no further
contributions will be made.  The trustee will continue to hold the funds and
make distributions as if the Plan had not terminated.

C.  TRUSTEE AND ADMINISTRATION OF THE PLAN:

Putnam Fiduciary Trust Company has been designated as trustee.  Investments of
the Plan are held by Putnam Investor Services, Inc. on behalf of the trustee.

The Company has established a Savings and Investment Plan Committee for the
general administration of the Plan.

The Company pays the trustee fees on behalf of the Plan.

D.  INTERNAL REVENUE SERVICE STATUS:

The IRS has issued determinations that the Plan, as originally adopted January
1, 1985, and as amended through January 17, 1994, is a qualified plan for tax
purposes under Sections 401(a) and 401(k) of the Internal Revenue Code, and that
the trust established in connection therewith is exempt from income tax under
Section 501(a) of the Code.  The Company believes the Plan as presently
constituted and operated continues to meet the requirements of Sections 401(a)
and 401(k) of the Code and that the related trust is exempt from income tax
under Section 501(a) of the Code.
