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.
On June 30, 2015 McGraw-Hill Education announced that Data Recognition Corporation (DRC) had agreed to acquire "key assets" of the CTB/McGraw-Hill assessment business.
Many sections take fifteen minutes to a few hours, and the tests sometimes extend to over one day.
Typically this is expressed as a raw score that is then converted into a percentile ranking.
This is different from criterion-referenced tests, which measure student performance based on mastery of the material.
