Dear Parent/Guardian:
Your child recently took the Cognitive Abilities Test (CogAT). This test consists of three batteries: verbal, quantitative, and nonverbal. The verbal battery measures how well the student is able to learn and solve problems related to words. The quantitative battery measures the development of numerical concepts. The nonverbal battery assesses skills in using figures and pictures to solve problems. The test appraises the level and pattern of developed abilities which are influenced by experiences both in and out of school, and assists educators in determining instructional strategies that would best meet the needs of your child. The results for your child are reported on the enclosed Profile Narrative. Scores are expressed as:
Age Scores – indicate your child’s performance relative to other students approximately the same age who were administered the test nationally.
Raw Scores – indicate the number of test items for each battery, the number of responses your child attempted, and the number of test items your child answered correctly for each battery.
Grade Scores – indicate your child’s performance relative to other students in the same grade who were administered the test nationally.
- Standard Age Scores range from 50-150, with 100 being the midpoint or median.
- Stanines compare a student’s performance with that of the national sample. Stanines range from 1 to 9, with the 5th stanine being the midpoint or median.
- Percentile ranks range from 1 to 99, with the 50th percentile being the midpoint or median. A percentile rank of 45 would mean that the student performed as well or better than 45 percent of the students in the national sample. It does not mean that the student answered 45 percent of the questions correctly.
As is true of any standardized test, this test measures only a sample of the skills that could be tested, and the results represent the performance of the student on the day or days tested. Test scores should never be used alone to make decisions about a student and can be helpful when used with other information.
If you have any questions about this score report, please contact your child’s school.
