Who Takes the CogAT?
All 3rd graders are screened for AIG services in the fall using the CogAT. Select 4th and 5th graders also take it as part of the identification process.
What is the CogAT?
The CogAT is a test of reasoning skills – It is not like a spelling or a math test where if you know the words or the facts you can get 100%. There is no defined curriculum for the CogAT. 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.
