Who Takes the CogAT?

All 2nd graders are screened for AIG services in the Fall.  

What is the CogAT?

The CogAT  is a test of reasoning skills – It is not a part of the 2nd grade curriculum. It is a norm-referenced test and the national average is 50th percentile. There are three parts to the CogAT: Verbal Battery, Quantitative Battery, and Non-Verbal Battery. 

What batteries are on the CogAT?

Verbal Battery 

The Verbal Battery tests a student's vocabulary, as well as his/her comprehension of ideas, efficiency and verbal memory, and ability to discover word relationships. Statistics show a high correlation between high verbal ability and success in a variety of school subjects. 

Quantitative Battery 

The Quantitative Battery tests the student's quantitative reasoning and problem solving ability and provides an appraisal of the student's general level of abstract reasoning. 

Non-Verbal Battery 

The Nonverbal Battery presents the most novel problems to students. The items on these tests use only geometric shapes and figures.

How do we combine these scores?

The Verbal-Nonverbal Partial Composite (VN) combines the three Verbal subtests and the three Nonverbal subtests.  This composite score is a good predictor of achievement in reading and language arts.  We use this score for reading identification.

The Quantitative-Nonverbal Partial Composite (QN) combines the three Quantitative subtests and the three Nonverbal subtests.  This composite score better predicts achievement in mathematics.  We use this score for math identification.

The Full Composite (VQN) indicates the overall strength of the student’s cognitive resources for learning.  We use this score for math and reading identification.

What score does my child need to qualify for A.I.G.?

Students need to score in the 95th percentile on a given battery and evidence of level 4 performance in Reading, or Math in order to qualify for AIG services.
