Learn about how the OLSAT is scored and how to interpret your results. TestPrep-Online can help your child improve his/her OLSAT score with online practice tests, hundreds of sample questions, and helpful study guides.

When Will I Receive My Child's Scores?

You can expect to receive your child’s OLSAT scores in the mail about two months after the test is taken. OLSAT score reports are detailed and will give you an idea of whether or not your child qualifies for a gifted program.

How Are Scores Calculated?

The OLSAT is scored in three basic steps:

  • Raw Score: The raw score is calculated by adding up the total number of questions answered correctly. For example, if your child answers 45/60 correctly, their raw score is 45. The score report will include a raw score for the verbal and nonverbal sections (each out of 30) as well as the overall raw score (out of 60).
  • School Ability Index (SAI): The raw score is converted using the School Ability Index (SAI). The SAI score is determined by comparing scores of children within the same age group. The maximum SAI score is 150. The average SAI score is 100, and the standard deviation is 16.
  • Percentile Rank: The SAI score is used to determine an overall percentile rank. This score compares your child to other students in the same age group. For example, if your child ranked in the 85th percentile, it means they scored as well as or higher than 85% of children within the same age group.

What Is a Good OLSAT Score?

There is no such thing as a "good" score on the OLSAT–it all depends on the context. When it comes to gifted programs, the qualifying score may vary from one to the next. Typically, a gifted child falls two standard deviations above the mean. Given that the mean is 100, and the standard deviation is 16, this equates to an SAI score of 132.

Eligibility for Gifted Programs

Gifted schools and programs vary on their admission requirements. As stated above, a score of 132 could be considered a typical cutoff score for gifted programs. This means that gifted programs generally require a student to score in the top 1-3%, or above the 97th percentile. Find out more about gifted testing and programs in your local school district.

"My daughter and I had a great experience practicing at home for her G&T exam. She enjoyed using the pack and had fun doing the practice questions. The video academy and parent guide were great, and the product tour helped us to figure out how to use the pack. Parents, if you are looking for G&T at-home practice, I recommend TestPrep-Online!"
