                         PLATO LEARNING, INC. ANNOUNCES
                  AGREEMENT TO ACQUIRE NETSCHOOLS CORPORATION


MINNEAPOLIS, MN - May 9, 2002 -- PLATO Learning, Inc. (Nasdaq:TUTR), a leading
provider of computer-based and e-learning instruction, announced today that it
has signed a definitive agreement to acquire NetSchools Corporation, a provider
of Internet-based e-learning software and services solutions for the K-12 market
by offering a web-based curriculum and instructional management delivery
platform that facilitates delivery of school curriculum aligned to local, state
and national standards and facilitates online assessment, lesson planning and
content delivery. The acquisition will enhance PLATO Learning's ability to
provide enterprise-wide solutions that align classroom education across all
standards and deliver compelling and effective content through NetSchools'
instructional management platform.

PLATO Learning is acquiring all the shares of privately-held NetSchools for $6.0
million in cash; 800,000 shares of PLATO Learning stock; 200,000 warrants for
shares of PLATO Learning stock; assumed liabilities and transaction expenses;
and additional consideration of up to approximately $6.0 million, contingent on
the NetSchools' product and services revenues generated through October 2004.
The transaction is expected to close no later than May 17, 2002, following
satisfaction of certain conditions to the transaction.

NetSchools generated revenues of approximately $16.0 million in calendar 2001,
of which about $4.0 million was software and services related and the balance
was hardware sales. The acquisition is expected to be dilutive to PLATO
Learning's earnings per share in the remainder of it's current fiscal year
ending October and in the earlier quarters of fiscal 2003. The transaction is
expected to become accretive in the latter quarters of the fiscal year ending
October 2003. PLATO Learning will be providing revised revenue and earnings
guidance for the remainder of fiscal 2002 during its second quarter earnings
release call, which is tentatively scheduled for June 5, 2002.

The acquisition will bring together Orion and Constellation, NetSchools' leading
curriculum platforms; TeachMaster, PLATO Learning's standards-based curriculum
company; and PLATO Learning's core curriculum products, creating a
comprehensive, highly customizable, open architecture education delivery
platform that is fully correlated with local, state and national standards.



                                                                               1





John Murray, President and CEO of PLATO Learning, said "We believe this
combination will position PLATO Learning to be the first company in the K-12
space to provide a complete, standards-based, e-learning platform that
incorporates all of a school district's instructional resources - including
textbooks, workbooks, lesson plans, best practices, and computer-based lessons -
fully correlated with state and national standards and easily integrated by
classroom teachers into their daily activities.

This acquisition of NetSchools, in combination with the current TeachMaster and
PLATO Learning products, creates a powerful suite of integrated CD-ROM, LAN and
web-based curriculum and instructional management products that are capable of
fully supporting a school district's investment in meeting accountability
demands. We see the addition of the NetSchools Constellation and Orion
platforms, which allow teachers to coordinate standards-based classroom
instruction based on all available district resources, as adding significant
strength to our already strong position in local and web-based supplemental and
core curriculum solutions for K-12 education."

The recently enacted education reform bill, No Child Left Behind, provides a
significant opportunity to help teachers, schools, and districts address the
accountability demands of parents. Mr. Murray commented that, "Despite the fact
that this transaction will be dilutive in the short-term, primarily because of
the subscription nature of the NetSchools business model, we are confident this
combination positions us to take both a leading role in this fast-growing market
and accelerate growth as districts seek to implement the new legislative
requirements. Clearly, for school districts to succeed in meeting the demands of
accountability, they must engage the use of technology in assisting teachers in
the classroom as well as with communicating with the community and parents. The
new PLATO Learning solutions afforded by the acquisition of NetSchools meets
these contemporary district needs and it is also highly complementary to our
core curriculum business." Mr. Murray added, "We believe owning the curriculum
platform in schools is critical to our long-term vision of selling
enterprise-wide, subscription-based, school and community programs. However, we
also recognize every school must combine a wide-range of educational content to
meet every student's needs. We will now have available to us both a new emerging
market, as well as a piece of the market that was previously only available to
certain competitors."

NetSchools' co-founder and Vice Chairman, Tom Greaves will remain active in
developing and promoting the combined strategic and selling efforts of the
merged entities. Scott Redd, NetSchools' Chairman, President and CEO will remain
as a consultant to Mr. Murray and PLATO Learning. Mr. Redd commented, "We
believe the combination of NetSchools' web-based e-learning platforms with the
TeachMaster standards driven products and the PLATO Learning courseware and
learning management systems will create a powerful new K-12 solution for
providing comprehensive, interactive, standards-referenced classroom
instruction. The combined entity will have a distinct and significant strategic
advantage, as well as financial stability and profitability, making it unique in
the educational software industry."
