Edusoft Assessment Management System Selected as 2007 Codie Awards Finalist

CHICAGO — January 18, 2007 — Riverside Publishing, a division of Houghton Mifflin Company and leader in comprehensive educational standards-based assessment, announced today that its flagship formative solution,  Edusoft Assessment Management System, was selected as a 2007 Codie Awards finalist. Established in 1986 by the Software & Information Industry Association (SIIA), the Codie Awards celebrate outstanding achievement and vision in the software, digital information and education technology industries.

"The 2007 Codie finalists represent real winners, even at this stage of the contest," said Ken Wasch, president, SIIA. "Competition is fiercer than ever and that makes selection as a Codie finalist a major achievement."

A distinguished panel of reviewers from the education, information technology, trade press and consulting industries selected Edusoft from a pool of more than 1,200 nominations. The Edusoft Assessment Management System was chosen as a "Best Student Assessment Solution" finalist — a category Edusoft won in 2005.

"We are extremely pleased that Edusoft has been selected by industry experts as a finalist out of so many competing nominations," said Michael Perik, chairman, Houghton Mifflin Assessment Division. "This honor reinforces to us that Edusoft is a true leader in the highly competitive formative assessment market."

The Edusoft Assessment Management System is a standards-based assessment solution that gives school districts powerful tools to help improve classroom instruction and student performance. With the latest version, Edusoft 4.0, educators have the flexibility to choose to deliver tests online, on paper, or through a combination of these delivery mechanisms. With Edusoft, educators can instantaneously access reports for online tests; view students’ online and paper test results together or separately; and quickly score multiple choice, short answer and constructed response questions. Edusoft 4.0 also features several content enhancements, including new high school item banks, Lexile scores for reading passages and Bloom's Taxonomy and cognitive difficulty indicators.

The 2007 Codie Awards will be presented at a gala event on April 17 at the Palace Hotel in San Francisco, California.
