OLSAT Test, Otis-Lennon School Ability Test  is a widely used measure of abstract thinking and reasoning ability appropriate for students between the ages of 5 and 18. The test includes both verbal and nonverbal items. The OLSAT does provide scoring comparisons both by age and grade and it was standardized on a large representative sample of the U.S. school population. It is typically administered in a group setting and may take 60-75 minutes, depending on the grade level of the child. Younger children are sometimes administered the test in two settings. OLSAT is given in combination with Stanford 10, a score called an Achievement/Ability Comparison (AAC) is obtained. AACs describe a student’s achievement in relation to the achievement of students with the same measured school ability. This is an important distinction, since students whose achievement appears to be below average
when compared with a national sample of all students may in fact be achieving at a higher or lower level in comparison with students of the same measured school ability.  Scores obtained from combined achievement ability testing give educators a more complete picture of each student’s potential for success in school when prepping for the Olsat.
