Superintendents tell us they want teachers to have access to online databases that fully align assessment questions, instructional content, learning exercises and lesson plans with their state learning and testing standards. They also want teachers to have the ability to automatically manage these important resources, on demand, as they instructionally plan and, based on each student’s need.” Mr. Murray continued, “With the integration of TeachMaster’s 49 state database of over 48,000 state and national standards, and more than 125,000 associated benchmarks, into and aligned with our comprehensive core curriculum products, PLATO is positioned to be the leading provider of both the tools and services needed to achieve meaningful standards-driven results in the classroom.”

PLATO Learning’s heritage of innovation, instructionally sound multimedia courseware, quality service and support, as well as its sustained growth and profitability, make it unique in the educational software industry. We are very excited to join the PLATO Learning family and to team with both PLATO and educators from around the world to design, build and implement educational software and learner management solutions that will truly make a difference in a standards driven education environment.”
