- OLSAT is Pearson's Eighth Edition, Form 5, published in 2003, with no ninth edition announced.
- Seven levels (A-G) map to kindergarten through grade 12; item counts run from about 40 to 72.
- Scoring uses the School Ability Index (mean 100, standard deviation 16), not a pass/fail score.
- Only Verbal, Nonverbal, and Total scores are reported - no breakdown by the five domains.
Quick Facts Snapshot
Before diving into domains and timing, here is the condensed reference sheet every parent, teacher, or tutor searching for a fast OLSAT refresher actually needs. Every figure below comes straight from Pearson's published specifications for the Otis-Lennon School Ability Test - nothing here is borrowed from an unrelated credential that happens to share the acronym.

The Seven Levels at a Glance
OLSAT is not one fixed test - it is seven distinct forms, each calibrated to a grade band. Getting the level right matters more than almost anything else in preparation, because item difficulty, vocabulary, and even how questions are delivered change from level to level.
- Level A - Kindergarten
- Level B - Grade 1
- Level C - Grade 2
- Level D - Grade 3
- Level E - Grades 4-5
- Level F - Grades 6-8
- Level G - Grades 9-12
A critical distinction: at Levels A through C, the test administrator reads every question and every direction aloud. This is intentional - Pearson designed the early levels to measure reasoning ability independent of a young child's decoding skills. Starting at Level D, students read items independently. This single design choice explains why a Level C practice session looks and sounds nothing like a Level F session, even though both are technically "OLSAT."
Key Takeaway
Confirm the exact level your child or student will sit for before buying any practice material - Level and grade determine everything else on this page.
The Five Exam Domains
OLSAT content is organized into five reasoning domains rather than school subjects like math or reading. Two of the five domains are level-restricted, which is a detail many families miss.
Domain 1: Verbal Comprehension
Tests whether a student can understand relationships expressed in words - following directions, understanding sentence meaning, and grasping vocabulary in context.
- Appears across the level range, adjusted for grade-appropriate vocabulary
Domain 2: Verbal Reasoning
Measures logical thinking expressed through language, such as identifying analogies, classifying words by shared properties, or drawing inferences from a short verbal prompt.
- Pairs with Verbal Comprehension to form the Verbal score reported to schools
Domain 3: Pictorial Reasoning
Uses pictures of familiar objects and scenes rather than abstract shapes, asking young test-takers to complete a series, spot an analogy, or identify what's missing.
- Appears only at Levels A through C - it disappears entirely once students move to Level D
Domain 4: Figural Reasoning
Uses abstract shapes, patterns, and designs to assess nonverbal problem-solving - the classic "what comes next in this sequence" style of item.
- Spans the full level range, from early grades through Level G
Domain 5: Quantitative Reasoning
Assesses number relationships, patterns, and basic quantitative logic without requiring computation skill beyond grade expectations.
- Appears only at Levels D through G - it is not tested at the earliest levels
Because no single level administers all 21 individual item types across these five domains, a Level B test and a Level G test can feel like entirely different exams even though both report a Verbal and Nonverbal score. For a deeper breakdown of item types within each domain, see the OLSAT Exam Domains 2026 guide.
Format, Timing, and Item Counts
Pearson officially states the test is untimed with a 75-minute maximum and does not publish exact item counts or per-level timing. That said, independently reported figures are consistent enough to plan around:
- Pre-K variant of Level A: about 40 items
- Levels A through C: about 60 items each
- Level D: about 64 items
- Levels E, F, and G: about 72 items each
Across every level, items split evenly between verbal and nonverbal content, which lines up with the two domains reported on the final score. All items are multiple choice - there are no written-response, essay, or open-ended components at any level. Because the format never changes, familiarity with how OLSAT questions are worded matters more than raw content review. Readers weighing how much prep time to budget should also read How Hard Is the OLSAT Exam? Complete Difficulty Guide 2026, which unpacks why the untimed format changes the pressure profile compared to a timed test.
How Scoring Actually Works
There is no pass or fail on the OLSAT. Instead, Pearson reports a School Ability Index (SAI) - a normalized standard score with a mean of 100 and a standard deviation of 16, which is worth remembering because it differs from the standard deviation of 15 used by many other standardized assessments. Alongside the SAI, score reports include:
- Percentile rank, calculated by both age and grade
- Stanine, also by age and grade
- Normal Curve Equivalent (NCE)
- Scaled scores
Only three composite scores are reported: Verbal, Nonverbal, and Total. There is no domain-level subscore, so a student's exact performance on, say, Figural Reasoning versus Quantitative Reasoning is never broken out on the official report. Districts and organizations interpret the SAI and percentile rank according to their own thresholds - Pearson does not define a universal cutoff. For a full explanation of what a "good" score looks like in context, see OLSAT Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Memorize this one number: SAI mean is 100, standard deviation is 16. Confusing it with a 15-point standard deviation scale will throw off any percentile estimate.
Cutoffs and Benchmarks Worth Knowing
Because Pearson doesn't set a universal passing line, real-world benchmarks come from the institutions that use the test. Two concrete examples are worth memorizing for this cheat sheet:
- Los Angeles Unified School District tests all second graders during March and April and identifies students for gifted programs at the 95th percentile and above.
- American Mensa accepts a School Ability Index of 132 as qualifying evidence of eligibility.
Notably, New York City no longer uses the OLSAT for its gifted and talented admissions process, which is a common point of confusion for families researching older articles online. Retake policy is also not standardized by Pearson - it is entirely controlled at the district level, and scores themselves do not expire.
Registration, Ordering, and Cost Mechanics
Unlike many assessments, individual parents cannot simply buy the OLSAT. Pearson sells directly to schools and districts under Qualification Level B, which requires a $500 minimum initial order. Rough pricing benchmarks include:
- Starter kits from $82.00
- Practice tests at $16.00 per 10
- Scoring at roughly $3.93 to $4.79 per student
Homeschool families are not left out entirely - they can test through authorized resellers at approximately $40 per student, since Pearson restricts direct sales to schools and qualified professionals. This ordering structure is a key reason why so much OLSAT information circulates through schools rather than open retail channels. For a complete pricing breakdown, including how these figures compare across purchase types, see OLSAT Certification Cost 2026: Complete Pricing Breakdown.
Because access runs through institutions, most independent preparation happens through practice resources rather than official retail purchases - which is exactly the gap that our practice test platform is built to fill for families preparing outside a classroom setting.
A Focused One-Week Review Plan
Generic study calendars rarely account for how OLSAT content is structured, so this plan is built around the actual level and domain restrictions covered above rather than a one-size-fits-all study method.
Confirm Level and Domains
- Verify the exact level (A-G) your student will take
- If Level A-C, prioritize Pictorial Reasoning practice; if Level D-G, prioritize Quantitative Reasoning instead
Verbal Domains
- Drill Verbal Comprehension items focused on following multi-step directions
- Practice Verbal Reasoning analogies and classification questions matched to grade vocabulary
Nonverbal Domains
- Work through Figural Reasoning pattern-completion sets, since this domain spans every level
- Layer in the level-appropriate domain (Pictorial or Quantitative) identified on Days 1-2
Simulate Conditions
- Run a full untimed session capped near 75 minutes to build stamina without inducing timed-test anxiety
- Review missed items by domain, not just by right/wrong count
Because the test itself is untimed, the goal of this week isn't speed drilling - it's exposure to question phrasing and format consistency across the five domains. Families wanting a longer-horizon version of this plan, including how to sequence weeks across a full preparation cycle, should read the full OLSAT Study Guide 2026.
Key Takeaway
Spend the most practice time on whichever level-restricted domain (Pictorial or Quantitative) actually applies to your student's level - the other one will never appear on their test.
Frequently Asked Questions
Pearson states the test is untimed, with a maximum administration time of 75 minutes. Exact per-level timing is not officially published.
Pearson does not publish official item counts, but independent sources consistently report roughly 40 items on the pre-K variant of Level A, about 60 at Levels A through C, 64 at Level D, and 72 at Levels E, F, and G.
No. Pearson sells to schools and qualified professionals under Qualification Level B with a $500 minimum order. Homeschool families typically test through authorized resellers at about $40 per student.
There is no universal passing score. The School Ability Index has a mean of 100 with a standard deviation of 16; specific benchmarks vary by district, such as LAUSD's 95th-percentile gifted threshold or American Mensa's accepted SAI of 132.
No. Pictorial Reasoning appears only at Levels A through C, and Quantitative Reasoning appears only at Levels D through G, so no single level covers all 21 item types across the five domains.
