Riverside Publishing Announces Online Version of the Gates-MacGinitie Reading Tests

Tests Offer Educators a More Convenient Method to Measure Critical Reading Skills

ITASCA, Ill. — October 5, 2006 — Riverside Publishing, a division of Houghton Mifflin Company and leader in comprehensive educational standards-based assessment, today announced the online version of the Gates-MacGinitie Reading Tests (GMRT^®), Fourth Edition, which offers educators the option to administer the popular tests via the Internet.

GMRT is a powerful assessment educators use to help determine their students' level of reading achievement. GMRT is developmentally appropriate for all learners and well suited to the Reading First and Striving Readers programs. The objective information obtained from the tests can be used in a variety of ways: reporting student progress to parents, teachers and the community; evaluating the effectiveness of instructional programs; and selecting students for individual diagnosis and special instruction.

"With GMRT online, educators will receive the same great features that have made the GMRT paper-pencil version a classroom favorite," said Lee Jones, president, Riverside Publishing. "GMRT online offers the same reliability of the paper-pencil version with the flexibility and convenience of online testing. The online version of the GMRT will give educators instant access to their students' test results with a dynamic, Web-based reporting tool."

Both the online and paper-pencil versions of the GMRT are now available. For more information on the Gates-MacGinitie Reading Tests, please visit www.riversidepublishing.com or call 800-323-9540.
