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.
