Note 1.  Operations and Significant Accounting Policies
         ----------------------------------------------

         The accompanying condensed consolidated financial statements have been
prepared by the Company pursuant to the rules and regulations of the Securities
and Exchange Commission.  Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such
regulations.  Certain prior period balances have been reclassified to conform
with the current period presentation.  The condensed consolidated financial
statements reflect all adjustments and disclosures which are, in the opinion of
management, necessary for a fair presentation.  All such adjustments are of a
normal recurring nature. The condensed consolidated financial statements in this
Quarterly Report on Form 10-Q should be read in conjunction with the
consolidated financial statements and notes thereto for the fiscal year ended
September 30, 1997 that are contained in the Company's 1997 Annual Report on
Form 10-K.


Note 2.  Computation of Net Income per Common share and Common Equivalent Share:
         ---------------------------------------------------------------------- 

         The Company has adopted Financial Accounting Standards No. 128 (SFAS
No. 128) "Earnings per Share" as of the start of fiscal 1998. Accordingly, the
net income per common share and common equivalent share for fiscal 1997 has been
restated to reflect the adoption of SFAS No. 128. The difference between the
weighted average number of shares outstanding and the diluted shares outstanding
is due to stock options. To calculate the number of diluted shares outstanding,
the treasury stock method was used. For the three and six month periods ended
March 31, 1998, 8,000 shares and 41,000 shares, respectively, were added to the
weighted average number of shares outstanding. For the three and six month
periods ended March 31, 1997, 93,000 shares and 66,000 shares, respectively,
were added to the weighted average number of shares outstanding.


Note 3.  Litigation:
         -----------

         On April 16, 1998, a class action lawsuit was filed against certain
officers and directors of the Company in the Superior Court of the State of
California, County of Los Angeles, purportedly on behalf of those who purchased
the Company's Common Stock between May 8, 1997 and November 3, 1997.  The
Company has not been named in the suit, but has indemnification agreements with
such officers and directors.  The Company has obtained a copy of the complaint
which alleges violations of California law.  The complaint alleges that the
named officers and directors concealed an alleged deterioration of its business
in early 1997 and realized profits by trading their shares of Company Common
Stock while in possession of the alleged material adverse information.  The
complaint seeks an unspecified amount of compensatory damages and, additionally,
seeks attorneys' and other costs, interest, and other relief.

         The named officers and directors have not yet filed answers to the
complaint but have indicated that they intend to defend themselves vigorously in
this proceeding.  The Company is unable to estimate the outcome of this matter
or any potential liability it may incur.   The Company does have directors' and
officers' insurance coverage.  Even if the defendants prevail on the merits in
such litigation or the costs are covered by insurance, the Company expects to
incur legal and other defense costs as a result of such proceeding.  This
proceeding could involve a substantial diversion of the time of some members of
management, and an adverse determination in, or settlement of, such litigation
could involve the payment of significant amounts or could include terms in
addition to such payments, which could have an adverse impact on the Company's
business, financial condition, results of operations and cash flows.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

OVERVIEW

     Learning Tree International, Inc. (the "Company"), is a leading worldwide
provider of education and training for corporate information technology ("IT")
professionals in business and government organizations.  The Company develops,
markets and delivers a broad, proprietary library of instructor-led course
titles focused on client/server systems,  intranet/Internet technologies,
computer networks, operating systems, databases, programming languages,
graphical user interfaces, object-oriented technology and IT management.  The
Company also tests and certifies IT professionals in 29 IT job functions.  The
Company's instructor-led courses are recommended for college credit by the
American Council on Education.

     During 1997, the Company expanded the breadth of its instructor-led
training activities through the introduction of its Learning Solutions Division.
The Learning Solutions Division provides custom developed training programs for
larger clients who need to train large numbers of their IT professionals and
end-users.  The focus of this new division is on training that supports the
roll-out and use of new organization-wide information systems, tools and
applications. Its first program was for General Motors Corporation, and was
largely completed in the first quarter of fiscal 1998.  The Company is currently
working on a smaller follow-on program with General Motors, and is seeking
additional contracts with other potential customers.  Because this business
depends upon obtaining a small number of large contracts, its revenues are
inherently subject to fluctuation.

     In addition to its instructor-led courses, the Company develops, produces
and markets a line of interactive computer-based training courses incorporating
audio and graphical elements ("multimedia CBT") that are designed for both
stand-alone CD-ROM and network-based delivery.  The Company has been marketing
its multimedia CBT products through direct mail and telemarketing methods, which
focus on high volumes of comparatively smaller unit sales.  The Company also
markets its multimedia CBT products through field sales of higher value
multimedia CBT contracts.  To date, the majority of the Company's multimedia CBT
revenues have been obtained through direct mail and telemarketing.

     In 1997, the Company also introduced a program of "Power Seminars," which
were multi-day conferences consisting of a number of 1-day, multimedia lecture-
style seminars in key information technologies.  In November 1997, the Company
announced that it was eliminating its Power Seminars program.  Operations in the
Power Seminars program ceased as of the end of the first quarter of fiscal 1998.

RESULTS OF OPERATIONS

     In the second fiscal quarter ended March 31, 1998, revenues increased by
$9.2 million or 26% to $45.0  million from $35.8 million for the corresponding
quarter of the prior year.   Income from operations for the quarter ended March
31, 1998  increased $92,000 or 4% to $2.5 million versus $2.4 million for the
same quarter of fiscal 1997.  Net income for the quarter ended March 31, 1998
was $2.1 million which was unchanged from the quarter ended March 31, 1997.

     For the six month period ended March 31, 1998, revenues increased by $18.4
million or 26% to $90.2 million from $71.8 million for the six months ended
March 31, 1997.  Income from operations for the six months ended March 31, 1998,
decreased $4.1 million or 52% to $3.9 million versus $8.0 million for the
corresponding period of the prior year.  Net income for the six months ended
March 31, 1998 decreased $2.8 million or 45% to $3.4 million versus $6.2 million
for the corresponding period of the prior year.

     The growth of revenues in the second fiscal quarter was due, in large part,
to an increase in the number of course participants in multi-day instructor-led
courses to 27,765 in the quarter ended March 31, 1998 versus 22,998 participants
in the corresponding quarter of the prior year.  For the six months ended March
31, 1998, the number of multi-day instructor-led course participants was 54,063
compared to 47,027 in the corresponding six month period of the prior year.
The additional course participants are primarily attributable to increased
marketing and sales expenditures and an increase in the net number of
instructor-led course titles to 146 in the second quarter of fiscal 1998
compared to 124 in the same period a year earlier.  Revenues for the three and
six month periods ended March 31, 1998 also reflect a 4% increase in average
revenue per multi-day course participant, which resulted from increases in
average course duration and prices. The increase in revenues also reflects
revenues earned by the Company's Learning Solutions Division under its contract
with General Motors to train General Motors' personnel and dealers on the use
and support of a new proprietary information system, GM ACCESS, as well as the
growth of revenues from the multimedia CBT product line.

                                       7

     The Company's cost of revenues for its instructor-led courses primarily
includes the costs associated with course instructors, course materials, course
equipment, freight, classroom facilities and refreshments.  For  multimedia CBT
courses, cost of revenues primarily includes the costs of amortized development,
manufacturing, distribution and support.   The cost of revenues decreased to
41.5% of revenues in the second quarter of fiscal 1998 compared to 43.2% in the
second quarter of fiscal 1997, primarily because of an increase in revenues per
instructor-led course event.  For the six months ended March 31, 1998, the cost
of revenues increased to 43.3% of revenues compared to 41.5% for the same period
in fiscal 1997, largely because of lower gross margins in the Power Seminars and
Learning Solutions product lines compared with the Company's traditional multi-
day instructor-led courses and multimedia CBT courses, and also because of the
increased cost per multi-day instructor-led course event.

     For the second quarter of fiscal 1998, cost of revenues increased $3.3
million or 21% to $18.7 million from $15.4 million for the same quarter of
fiscal 1997.  For the six months ended March 31, 1998, the Company's cost of
revenues increased by $9.2 million or 31% to $39.0 million from $29.8 million
for the corresponding period in the prior year.  The increases in the  cost of
revenues compared to the same periods in the prior year, are primarily the
result of  a) the increased number of multi-day instructor-led course events and
b) the costs associated with the increased sales in the multimedia CBT product
line.  The number of multi-day instructor-led course events increased 21% in the
quarter ended March 31, 1998 to 1,743 course events from 1,446 course events in
the quarter ended March 31, 1997.  For the six month period ended March 31,
1998, the number of instructor-led course events increased 15% to 3,369 from
2,931 for the corresponding period in the prior year.  Costs per multi-day
instructor-led course event  decreased approximately 2% in the second quarter of
fiscal 1998 compared to the second quarter of fiscal 1997. Costs per multi-day
instructor-led course event have increased approximately 5% for the first six
months of fiscal 1998 compared to the corresponding period of the prior year,
reflecting lower costs during the first quarter of fiscal 1997.  In January
1998, the Company signed an agreement to lease a new education center in the
United Kingdom which is anticipated to be operational in early fiscal 1999.  In
April 1998, the Company opened a new larger education center in Boston.

     Course development expense includes the costs of developing new course
titles and updating the Company's existing course library.  The principal costs
are for internal product development staff and independent consultants who serve
as subject matter experts.  Course development expenses increased by $349,000 or
15% to $2.7 million for the quarter ended March 31, 1998 versus $2.4 million in
the quarter ended March 31, 1997.   For the six months ended March 31, 1998,
course development expenses increased $1.1 million or 24% to $5.9 million from
$4.8 million for the corresponding period in the prior year.  These increases
reflect the costs associated with the Company's strategy of expanding its multi-
day instructor-led and multimedia CBT course libraries to meet its customers'
technology training needs and updating and maintaining the growing course title
libraries.  The Company plans to continue its strategy of expanding both its
instructor-led course library and its multimedia CBT library, including
additional titles in the areas of intranet/Internet technologies, computer
networking, Java, Windows NT, programming languages and databases.

     During the first quarter of fiscal 1998, the Company introduced a new web-
based engine for its multimedia CBT product line and is continuing to allocate
resources to develop new features and capabilities for this engine.  Since all
new CBT titles are being developed using this evolving engine, and because
resources are being allocated to adapt existing courses based on prior engines
to the new web-based engine, the rates of introduction of new CBT titles in the
first and second quarters were, and the expected release rate of new courses in
the next quarter is expected to be, less than during the fourth quarter of
fiscal 1997 when 24 CBT titles were released.  To date, the Company has released
104 multimedia CBT course titles.

     Sales and marketing expenses include salaries, commissions and travel-
related costs for sales and marketing personnel, the costs of designing,
producing and distributing direct mail marketing and media advertisements, and
the costs of information systems to support these activities. Sales and
marketing expenses increased $4.2 million or 37% to $15.6 million for the
quarter ended March 31, 1998 versus $11.4 million for the quarter ended March
31, 1997. For the six months ended March 31, 1998, sales and marketing expenses
increased $9.1 million or 43% to $30.4 million from $21.3 million for the
corresponding period in the prior year. The increase in sales and marketing
expenses occurred as a result of an increase in telemarketing and field sales
staff and increased direct mail marketing. The Company expects that there will
be a decrease in the rate of growth in sales and marketing expenses during the
second half of fiscal 1998 compared to the rate of growth in the first half of
fiscal 1998 in order to better match the current slower growth rate of revenues.
The decision to reduce the growth rate of sales and marketing expenditures in
upcoming quarters is subject to reevaluation from time to time based upon market
conditions and other factors.

                                       8

     General and administrative expenses increased $1.4 million or 34% to $5.6
million for the quarter ended March 31, 1998 compared to $4.2 million in the
same quarter of the prior year.  For the six months ended March 31, 1998,
general and administrative expenses increased $3.1 million or 39% to $11.0
million from $7.9 million for the corresponding period in the prior year.  The
increase in general and administrative expenses reflects increases in
information systems and other administrative staff and increases in facilities
related costs over the prior year.  As a percentage of revenue, these costs
increased to 12% in the six months ended March 31, 1998 from 11% in the
corresponding period of the prior year.

     Other income (expense) is comprised of interest income, interest expense,
foreign currency gains and losses and other.  Other income decreased $80,000 to
$730,000 for the quarter ended March 31, 1998 versus $810,000 for the
corresponding quarter in the prior year.  For the six months ended March 31,
1998, other income increased by $100,000 to $1.3 million from $1.4 million for
the corresponding six month period in the prior year.  The decreases in net
other income were primarily attributable to less interest income than in the
prior year.

     The provision for income taxes was $1.1 million for each of the second
fiscal quarters ended March 31, 1998 and 1997.  For the six months ended March
31, 1998, the provision for income taxes decreased $1.4 million to $1.8 million
from $3.2 million for the corresponding period in the prior year.  The decrease
in the income tax provision reflects the decrease in taxable income.

BACKLOG

     At March 31, 1998, the Company had a backlog of orders for instructor-led
courses in the amount of $29.4 million, which represented an 18% increase over
the backlog of $24.9 million at March 31, 1997.  Only a portion of the Company's
backlog is funded.  There can be no assurance that the growth in the backlog
will continue or that orders comprising the backlog will be realized as revenue.

FLUCTUATIONS IN QUARTERLY RESULTS

     The Company's operating results may fluctuate based on various factors,
including the frequency of course events, the number of weeks in a quarter
during which courses can be conducted, the timing, frequency and size of, and
response to, the Company's direct mail marketing and advertising campaigns, the
timing of the introduction of new course titles and alternate delivery methods,
the mix between customer-site course events and Learning Tree-site course
events, competitive forces within the current and anticipated future markets
served by the Company, the spending patterns of its customers, currency
fluctuations, inclement weather and general economic conditions.  Fluctuations
in quarter-to-quarter results may also occur as a result of differences in the
timing of, and the time period between, the Company's expenditures on the
development and marketing of its courses and the receipt of revenues.

     The Company's revenues and income have historically varied significantly
from quarter to quarter due to seasonality and other factors.  The Company
generally has greater revenue and operating income in the second half of its
fiscal year (April through September) than in the first half of its fiscal year
(October through March).  This seasonality is due in part to seasonal spending
patterns of the Company's customers arising from budgetary and other business
factors as well as weather, holiday and vacation considerations.  In addition,
the seasonality of the Company's operating results reflects the quarterly
differences in the frequency and size of the Company's direct mail marketing
campaigns.  There can be no assurance that these seasonal factors or their
effects will remain the same in the future.

LIQUIDITY AND CAPITAL RESOURCES

     Cash and cash equivalents and short-term interest-bearing investments
increased to $63.0 million at March 31, 1998 from $56.8 million at September 30,
1997, primarily as a result of cash provided by operations.  For the six months
ended March 31, 1998, cash provided by operations was approximately $13.1
million compared to $16.0 million during the same period in the prior year.  The
decrease in cash provided by operations reflects the decrease in profits and a
smaller increase in deferred revenues arising from prepaid multi-enrollment
programs.  These changes were offset in part by increased depreciation.  As of
March 31, 1998, the Company had a net working capital balance of $32.6 million.

     During the six months ended March 31, 1998, the Company invested $5.7
million in equipment and facilities compared to $10.0 million in the same period
of the prior year.  The higher level of investment during the prior year was
primarily related to the acquisition of additional course equipment to support
the higher growth rate of course events at that time, to upgrade course
equipment capabilities and to build-out office facilities.

     In January 1998, the Company entered into a lease agreement for a large
education center in the United Kingdom.  The Company expects to begin executing
courses in this new facility during the first fiscal quarter of 1999.  The terms
of the

lease will require lease payments of approximately $4.3 million per annum and a
cash deposit or letter of credit in the amount of approximately $10.0 million.
Any cash deposit will bear interest to the Company and the required level of the
cash deposit or letter of credit will decline if certain financial ratios have
been met. The Company expects to purchase additional course equipment and to
enter into leases for additional facilities in other existing course cities
during fiscal 1998. However, other than the foregoing transaction, as of March
31, 1998, the Company had no material future purchase obligations, capital
commitments or debt and believes that its cash and cash equivalents, its short-
term interest-bearing investments and the cash provided by its operations will
be sufficient to meet its cash requirements for the foreseeable future.

YEAR 2000 COMPLIANCE

     The Year 2000 Compliance issue exists as a result of the use of two digit
date fields, rather than four digit date fields, by many computer systems and
software applications to define the applicable year.  As the century changes,
systems which are not Year 2000 Compliant will recognize the year 2000 as 1900,
or not at all.  The inability to recognize or properly treat the year 2000 may
cause systems to process financial and operational information incorrectly.  The
Company has assessed and continues to assess the impact of the Year 2000
Compliance issue on its operations.  The Company believes, based upon its
internal reviews and other factors, that there will be no interruption of its
operations as a result of the Year 2000 issue.  It is expected that the future
internal and external costs to be incurred to make the Company's computer
systems and software Year 2000 Compliant will not have a material effect on the
Company's results of operations or financial position.  Additionally, the
computer software products sold by the Company are Year 2000 Compliant.
However, there can be no assurance that the Company's customers or vendors will
not be affected by the Year 2000 Compliance issue or that this will not affect
the timing or amount of the Company's products and services customers purchase
or vendors provide.

                          PART II - OTHER INFORMATION

Item 1:   LEGAL PROCEEDINGS

          On April 16, 1998, a class action lawsuit was filed against certain
          officers and directors of the Company in the Superior Court of the
          State of California, County of Los Angeles, purportedly on behalf of
          those who purchased the Company's Common Stock between May 8, 1997 and
          November 3, 1997.  The Company has not been named in the suit, but has
          indemnification agreements with such officers and directors.  The
          Company has obtained a copy of the complaint which alleges violations
          of California law.  The complaint alleges that the named officers and
          directors concealed an alleged deterioration of its business in early
          1997 and realized profits by trading their shares of Company Common
          Stock while in possession of the alleged material adverse information.
          The complaint seeks an unspecified amount of compensatory damages and,
          additionally, seeks attorneys' and other costs, interest, and other
          relief.


          The named officers and directors have not yet filed answers to the
          complaint but have indicated that they intend to defend themselves
          vigorously in this proceeding. The Company is unable to estimate the
          outcome of this matter or any potential liability it may incur. The
          Company does have directors' and officers' insurance coverage. Even if
          the defendants prevail on the merits in such litigation or the costs
          are covered by insurance, the Company expects to incur legal and other
          defense costs as a result of such proceeding. This proceeding could
          involve a substantial diversion of the time of some members of
          management, and an adverse determination in, or settlement of, such
          litigation could involve the payment of significant amounts or could
          include terms in addition to such payments, which could have an
          adverse impact on the Company's business, financial condition, results
          of operations and cash flows.
