Cognitive Abilities

The Cognitive Abilities Test (CogAT) measures students’ learned reasoning abilities in the three areas most linked toCAT - Cognitive Abilities Test academic success in school: Verbal, Quantitative and Nonverbal. Although its primary goal is to assess students’ reasoning abilities, CogAT can also provide predicted achievement scores when administered with The Iowa Tests.

While CogAT is well-suited to help educators make important student placement decisions, such as selecting students for Gifted and Talented programs, exclusive features such as the Ability Profile Score can be used to expand the educational opportunities of all students.


Reasoning abilities have substantial correlations with learning and problem solving, both in and out of school. CogAT’s measurement of three different content domains ensures that educators receive a balanced view of the child.

Each level of CogAT offers three test batteries:

  • Verbal

  • Quantitative

  • Nonverbal

CogAT can be administered in whole or in part, however, the most complete view of a student will be provided through administration of all three batteries.

For the Primary Edition (Levels K-2), two different subtests measure each reasoning ability. The Multilevel Edition (Levels A-H) uses three different subtests to measure each ability.  Use of a different item format on each subtest ensures that scores for each battery are not unduly affected by performance on a particular item type.
