Interpretation of Test Scores for the Highly Capable Program

CogAT – Cognitive Abilities Test

This multiple choice, norm-referenced cognitive abilities test yields separate scores for three reasoning abilities – Verbal, Quantitative, and Nonverbal. The Verbal battery of the test measures a student’s vocabulary, comprehension of ideas, verbal memory and word relationships. The Quantitative battery addresses number relationships and equations, problem solving and mathematical reasoning. The Nonverbal battery measures the manipulation and classification of shapes and figures.

A student’s score is based on the norms for students of the same age that took the test in a national sample. These scores are reported in national percentile ranks. A percentile rank compares the student’s scores to others who took the test. If a student was at the 80th percentile rank, it would mean that the student performed better on this assessment than 80 percent of his/her peers.
