TerraNova is a series of standardized achievement tests used in the United States designed to assess K-12 student achievement in reading, language arts, mathematics, science, social studies, vocabulary, spelling, and other areas. At The American School, the TerraNova Assessment is implemented in grades 3-11.  The results are nationally norm-referenced, meaning that students' scores reflect their achievement in comparison to all students who took the test nationally. Typically this is expressed as a raw score that is then converted into a percentile ranking. This data is important as we use it to compare student achievement at The American School with comparable cohorts in the United States. 

The TerraNova is an achievement test, not a proficiency test. Proficiency tests are those in which students have been taught all of the content and are now being tested on whether or not they “got” it.

Achievement tests include content students may not have been specifically taught, but that they could be expected to have mastered according to their cognitive ability / mental age.

  • TerraNova is one of the most respected and widely used achievement tests, measuring mastery in the core subjects. Its design is fresh and user-friendly, and its content current.
  • TerraNova provides detailed diagnostic information, norm- and criterion- referenced scores, and performance-level data.
  • TerraNova aligns to state standards and the National Assessment of Educational Progress (NAEP) framework.
  • The TerraNova achievement scores indicate how well the child is doing in relation to students across the USA.
  • These tests are commonly used to provide valid, reliable, and unbiased information about students' knowledge in various content areas.
  • Tests results provide information about how students are performing with respect to instructional objectives
