The Otis-Lennon School Ability Test (OLSAT) measures abstract thinking and reasoning for learning new material. It's the primary gifted screening test for New York City's Gifted & Talented program and dozens of other districts nationwide.

Test Structure
The OLSAT tests both verbal and nonverbal reasoning across 21 question types. Understanding the breakdown helps you focus your child's preparation on the areas that matter most.
Tests following directions, aural reasoning, arithmetic reasoning, and logical selection. Verbal questions account for roughly half the test.
Uses figural analogies, series, and classification with geometric shapes. No reading required for this section.
OLSAT runs in levels A–G by grade. Level A is for pre-K/kindergarten. NYC uses OLSAT alongside NNAT for its gifted screening.
Study Strategy
Verbal OLSAT demands strong listening comprehension. Read to your child and ask "what came first?", "why did that happen?" after each page.
Give multi-step instructions: "put your left hand on your head, then point to something blue." This directly mirrors OLSAT's Following Directions questions.
"What do apple, orange, banana have in common?" and "which doesn't belong: cat, dog, rose, fish?" Verbal classification is a core OLSAT skill.
OLSAT arithmetic reasoning is logic, not calculation: "If there are 5 birds and 2 fly away, how many are left?" Work through these verbally.
The OLSAT is timed and test anxiety is real. Practice answering questions under mild time pressure so test day doesn't feel unfamiliar.

The Otis-Lennon School Ability Test measures abstract thinking, verbal reasoning, and nonverbal reasoning. It's one of the oldest school ability tests in the U.S., most famously used by NYC's Gifted & Talented program.
New York City, Nassau County, and dozens of other districts use the OLSAT for gifted screening. Check your district's website to confirm which test your school administers.
OLSAT results are reported as stanines (1–9). Stanine 7, 8, or 9 is above average. Most NYC gifted programs require a combined OLSAT/NNAT score at the 97th percentile or above.
NYC tests pre-K (age 4) and kindergarten (age 5) for its Citywide Gifted Programs. Testing happens January–February for the following school year.
Raw scores convert to School Ability Indexes (SAI) then to stanines. NYC reports a composite percentile combining OLSAT and NNAT scores.
Practice
The OLSAT has 21 question types split between Verbal and Nonverbal sections. These examples show the five most frequently tested types.
✓ Answer: Ann
Aural Reasoning questions are read aloud to the child — they do not see the text. The test-taker must hold the logic in working memory and reason through it. Practicing multi-step logic chains verbally is the most direct preparation: "A is bigger than B, B is bigger than C, which is smallest?"
✓ Circle A; underline 4
Following Directions is unique to the OLSAT among gifted tests. It tests the ability to process multi-step oral instructions and execute them precisely. Practice giving your child two- and three-step instructions during daily life — "get your jacket, put it on the chair by the door, then come back" — and gradually increase complexity.
✓ Carrot — it is a vegetable, not a fruit
Verbal Classification asks children to find the category that unites most items, then identify the outlier. The trap is that multiple groupings are sometimes possible — "carrot is also orange like the others." Train your child to find the most precise category, not the first one that fits.
✓ Circle with a line through it
Figural Analogies follow the same A:B::C:D structure as verbal analogies, but with shapes. The relationship here is "shape with a bisecting line." Identify all attributes that changed from A to B (none — same modification was applied), then apply that same modification to C. These questions appear on both the OLSAT and NNAT.
✓ 32 — each number doubles
Number Series tests pattern recognition using numbers rather than shapes. The rule can be additive (+3, +5, +7…), multiplicative (×2), or alternating (two interlocked sequences). Always check at least three steps before committing to a rule — many children correctly identify the first step but miss that the rule itself changes.
Score Guide
The OLSAT reports a School Ability Index (SAI) with a mean of 100 and standard deviation of 16. NYC G&T programs use a combined OLSAT + NNAT composite score converted to a percentile.
In New York City, OLSAT and NNAT scores are combined equally into a composite score that determines eligibility. The 90th percentile composite qualifies for district gifted programs; the 97th percentile composite qualifies for the four citywide gifted programs (Anderson, NEST+m, TAG, and the Brooklyn School of Inquiry). Cutoff scores fluctuate each year based on the applicant pool — the 97th percentile one year may correspond to a slightly different raw score the next.
Outside NYC, most districts set their OLSAT gifted threshold between the 90th and 96th percentile. Always confirm with your district's gifted office — some use the OLSAT SAI directly, others use the national percentile rank (NPR) converted from it.
