The Cognitive Ability Test (CogAT) is a widely used group administered ability test. First developed and published in 1954 as the Lorge-Thorndike Intelligence test, it has been revised several times over the years to its current version: CogAT (Form 6). It is often used to identify gifted students and helps the parent understand their children’s cognitive strengths and weaknesses and learning styles.

These tests are non-refundable and can only be purchased by homeschool or small private school (enrollment under 250 or else email us).
The Otis-Lennon School Ability Test (OLSAT) is a test of abstract thinking and reasoning ability of children ages K to 18. The Otis-Lennon is a multiple choice test, and taken with pencil and paper. It measures verbal, quantitative, and spatial reasoning ability. The test yields verbal and nonverbal scores, from which a total score is derived, called a School Ability Index (SAI). It is useful for identifying gifted children and a child’s processing strengths and weaknesses. The test can be administered in groups.

Paper testing for Stanford and OLSAT is year-round. Can only be purchased by homeschool or private school and is non-refunable.
