Key takeaways
  • The OLSAT, or Otis-Lennon School Ability Test, is a standardized assessment that measures a child's reasoning skills and learning potential, making it particularly useful for identifying gifted students
  • Homeschoolers can access this 40-minute test through various providers, and its results can help guide curriculum choices and identify areas where a child may need more support.

The OLSAT, or Otis-Lennon School Ability Test, is a standardized assessment that measures a child's ability to process and understand new information. It helps identify gifted students and assess overall learning potential.

Research from the National Home Education Research Institute (NHERI) shows that homeschooled students typically score 15 to 25 percentile points higher than public school students on standardized academic achievement tests. According to the National Center for Education Statistics (NCES), approximately 3.3 million students were homeschooled in the United States as of 2023, representing roughly 6% of the school-age population.

What is the olsat?

The OLSAT stands for the Otis-Lennon School Ability Test. It's a multiple-choice test from Pearson Education. Unlike tests that check what kids have learned, the OLSAT looks at how well they can think, analyze, and learn new things. It's been used since 1936 to find gifted students and is now in its eighth edition. The test gives a School Ability Index (SAI) score, with a mean of 100 and a standard deviation of 16, plus percentile rankings and verbal/nonverbal subscores.

What the olsat measures

The OLSAT tests five important reasoning skills:

  • Verbal Comprehension: Checks vocabulary and understanding of complex ideas.
  • Verbal Reasoning: Looks at logical thinking with analogies and patterns.
  • Pictorial Reasoning: Involves interpreting visual info and solving picture problems.
  • Figural Reasoning: Assesses spatial skills and geometric patterns.
  • Quantitative Reasoning: Covers math problem-solving with numbers and patterns.

This broad approach shows how well a child can learn, not just what they know in specific subjects.

How homeschoolers can take the olsat

Homeschoolers can easily access the OLSAT through various testing providers. It's more available than some other standardized tests.

Olsat vs. cogat

Both the OLSAT and CogAT help find gifted students, but they work differently. The OLSAT takes about 40 minutes and has verbal and nonverbal parts. The CogAT, on the other hand, takes around 90 minutes and has three sections: verbal, quantitative, and figural reasoning. The OLSAT pairs well with the Stanford Achievement Test, while the CogAT often goes with the Iowa Assessments. For homeschoolers, the OLSAT is often easier because of its shorter format and remote testing options.

The bottom line

The OLSAT is a great way to understand your child's reasoning skills and learning potential. If you're a homeschooler looking into gifted programs, academic contests, or just want to know your child's strengths, this test gives a solid benchmark. With remote testing options, it's more accessible for homeschool families. The results can guide your curriculum choices and show where your child might need more challenge or support.

Co-founder, BetterSchool

Lisa is the co-founder of BetterSchool and a homeschool mom of three. BetterSchool administers the largest independent homeschool community in the country — over 350,000 families across all 50 states.

When COVID hit, Lisa and her husband pulled their children out of school and hit the road. Homeschooling wasn't the plan — it was a necessity. But somewhere along the way, the family fell in love with it: the time together, the ability to tailor lessons to each child's interests, learning at their own pace, the freedom to travel, eating healthy on their own schedule, and the countless other benefits that come with homeschooling.

As they traveled, Lisa kept discovering incredible hands-on learning experiences that most homeschool families had no way of finding. She built BetterSchool to make it easy for every family to find and book the experiences that make learning come alive.

Through her community, Lisa has helped hundreds of thousands of parents navigate homeschooling, while also helping local businesses find and serve the homeschool community. She is the former managing partner of a law firm focused on business law and mergers and acquisitions — BetterSchool is her second technology startup. She holds a J.D. from California Western School of Law and a B.A. from Penn State.
