SAT/OLSAT®—Stanford Achievement Tests with Otis-Lennon School Abilities Tests

Available year-round for grades 2–12, the Otis-Lennon School Ability Test® (OLSAT) is offered only in combination with a Stanford Achievement Test. It provides separate scores for both verbal and nonverbal reasoning/learning abilities.

The OLSAT® will assess developed reasoning and problem-solving abilities important for learning. When the combination tests are given, the results will allow the parent/teacher to compare the student's ability with his actual school achievement. Combined testing is recommended once about every 2–3 years. The approximate testing time is 3–6 hours for the complete battery of achievement tests and 1 hour for the OLSAT.

If you have any questions, please contact us to learn about test options available for you.
