Stanford 10 with OLSAT®

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.

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

Please note: BJU Press began using 2018 norms for the Stanford in the Spring of 2019. This new comparison group has a much higher number of private school students. The new ratio, where private school students far outnumber public school students, makes it more difficult for a student to receive a high percentile rank.

Test Details

Gifted programs often require abilities test scores. If you desire to help your child place into one of these, please check to see whether the tests we offer would meet program requirements.

Please do not order if you have used an abilities test within the past three months or will be using one again in less than three months. Per our contract with the test publisher, public school students are not permitted to use abilities tests, achievement tests or practice tests ordered from BJU Press.


The OLSAT lasts 1 hour, in addition to any time spent on the Stanford 10.

The test measures two areas:

  • Verbal skills (verbal comprehension and reasoning)
  • Nonverbal skills (figural reasoning, quantitative reasoning)


The OLSAT is available for Grades 2–12; however, some of these tests are restricted in certain states.

This abilities test must be ordered in combination with the Stanford 10 achievement test.

Tester Qualifications

It is critical that the publisher's guidelines for administering the tests be followed precisely—please review the tester qualifications. For help locating a tester or for the tester application, please visit our Test Administrator support page.

Testers approved for the Stanford 10 are also approved for the OLSAT.
