The Otis-Lennon School Ability Test, Eighth Edition (OLSAT 8), assesses student thinking skills and provides an understanding of a student’s relative strengths and weaknesses in performing reasoning tasks.

OLSAT features eye-catching graphics and a student-friendly easy-hard-easy format to keep students engaged and motivated.

Achievement/Ability Comparison Score

OLSAT may be administered in conjunction with the Stanford Achievement Series, Tenth Edition (SAT10), to obtain an Achievement/Ability Comparison Score to give educators a more complete picture of each student’s potential for success in school.
