Cognitive Abilities Test
The Cognitive Abilities Test (CogAT) is a group-administered K–12 assessment intended to estimate students' learned reasoning and problem solving abilities through a battery of verbal, quantitative, and nonverbal test items. The test purports to assess students' acquired reasoning abilities while also predicting achievement scores when administered with the co-normed Iowa Tests. The author of the test is David F. Lohman, professor emeritus at the University of Iowa.
