The TerraNova, Third Edition, Multiple Assessments (TerraNova 3) is a standardized norm-referenced achievement test that is administered to DoDEA students in grades 3-11. It contains a battery of multiple-choice and constructed-response questions that are specifically detailed to assess specific skills in each core subject area (Reading/Language Arts, Mathematics, Science, and Social Studies). The assessment compares an individual student's scores to scores from a "norms group" and provides educators a comprehensive tool to measure and monitor student progress relative to local, state and national standards.

The TerraNova CAT Plus Mathematics Computation Test is a standardized norm-referenced achievement test that is administered to DoDEA ELL students, Levels 1 and 2. The assessment compares an individual student's scores to scores from a "norms group" and provides educators a tool for assessing a student's ability to perform computations.

The National Assessment of Educational Progress (NAEP) has been providing valuable information about the academic performance of elementary and secondary students in America since 1969. NAEP results are not only comparable across the nation and the states, but they also measure progress over time to capture the most accurate and representative picture of student performance. Without these NAEP reports (commonly called "The Nation's Report Card"), produced through the voluntary participation of those selected for the assessment, we would lack the common yardstick needed to measure student performance objectively. Schools and students are chosen through a sampling process that is designed to reflect accurately our nation's twelve million fourth-, eighth-, and twelfth-grade students.
