Product Details

Gain a more robust understanding of a student's ability.

OLSAT 8 measures cognitive abilities that relate to a student's academic success in school. By assessing a student's verbal, nonverbal, and quantitative ability, OLSAT 8 supplies educators with valuable information to enhance the insights gained from traditional achievement tests.

Features & Benefits

  • Content clusters and item types include verbal, nonverbal, and quantitative.
  • Obtain student's Achievement/Ability Comparison (AAC) score when administered with the Stanford Achievement Test Series, Tenth Edition (Stanford 10).
  • Specialized statistical procedures and comprehensive review of all test items by minority-group educators help minimize ethnic, gender, cultural, and regional bias.
  • Evaluates a student's performance on a variety of tasks, including detecting likenesses and differences, recalling words and numbers, defining words, following directions, classifying, establishing sequence, solving arithmetic problems, and completing analogies.

Administration Options


Make a Reliable Achievement/Ability Comparison

OLSAT® 8 can be administered with Stanford 10 to relate a student's actual achievement with his or her school ability. When these tests are given in combination, an Achievement/Ability Comparison (AAC) score is obtained. AACs describe a student's achievement in relation to the achievement of students with the same measured school ability. AAC scores give educators a better understanding of each student's potential for success in school.
