Gifted Test Grades PreK–12

OLSAT Study Guide

The Otis-Lennon School Ability Test (OLSAT) measures abstract thinking and reasoning ability — both verbal and nonverbal. Widely used for gifted placement (especially NYC G&T programs), it tests how students reason, not what they've memorized. This guide covers all subtests across both batteries.

Exam Structure

What's on the OLSAT

Two batteries of equal weight. The Verbal Battery tests language-based reasoning; the Nonverbal Battery tests visual and quantitative reasoning. Together they form the School Ability Index (SAI).

Battery 1

Verbal Battery

50%

of total score

Aural Reasoning ~17%

Listen to a brief oral prompt, select the picture that answers it. Tests listening comprehension.

Verbal Comprehension ~17%

Answer questions about pictures, categories, and vocabulary. Tests conceptual understanding.

Verbal Reasoning ~16%

Analogies, detection of likenesses/differences, verbal inference. Tests abstract reasoning.

Battery 2

Nonverbal Battery

50%

of total score

Pictorial Reasoning ~17%

Picture analogies and classification. Identify the pattern using real-world pictures.

Figural Reasoning ~17%

Shape sequences, matrices, and figure analogies using geometric shapes. Tests abstract visual reasoning.

Quantitative Reasoning ~16%

Verbal Battery 3 subtests · 50%

1. Aural Reasoning (~17%)

The examiner reads a brief question aloud. Students select the picture that best answers the question. This subtest appears primarily at lower grade levels (PreK–2).

What it tests:

  • ›Listening comprehension and attention
  • ›Understanding spoken vocabulary in context
  • ›Matching verbal descriptions to visual representations

Example question type:

"Which picture shows something you would use to keep dry in the rain?" (student points to or marks the umbrella)

2. Verbal Comprehension (~17%)

Students answer questions about word meanings, categories, and the relationships between concepts. Tests breadth of vocabulary and categorical thinking.

What it tests:

  • ›Vocabulary knowledge and word definitions
  • ›Categorical classification of objects and concepts
  • ›Understanding synonyms, antonyms, and definitions

Example question type:

"Which word means the opposite of ancient? (A) modern (B) old (C) broken (D) heavy"

3. Verbal Reasoning (~16%)

Analogies, inference questions, and detecting likenesses or differences between words and concepts. This is the most demanding verbal subtest and requires abstract language reasoning.

What it tests:

  • ›Verbal analogy relationships (A:B :: C:D)
  • ›Inference and deductive verbal reasoning
  • ›Detecting which item does not belong to a group

Example question type:

"Glove : Hand :: Shoe : ___ (A) foot (B) sock (C) lace (D) boot"

Nonverbal Battery 3 subtests · 50%

1. Pictorial Reasoning (~17%)

Picture analogies and classification using familiar objects and real-world images. Students identify which picture shares a relationship or completes a pattern.

What it tests:

  • ›Nonverbal analogical reasoning using pictures
  • ›Visual classification and grouping by shared attributes
  • ›Recognizing functional or categorical relationships in pictures

Example question type:

"Bird : Nest :: Fish : ___ (student selects picture of a fish tank or river)"

2. Figural Reasoning (~17%)

Sequences and matrices of geometric shapes. Students must detect the rule governing the pattern and identify the missing element. Pure visual-abstract reasoning with no real-world objects.

What it tests:

  • ›Shape sequence and figure analogy reasoning
  • ›Detecting transformation rules (rotation, size, shading)
  • ›Applying visual rules in matrix format

Example question type:

"A series of shapes alternates between filled and unfilled and rotates 90° each step. What comes next?"

3. Quantitative Reasoning (~16%)

Number series, arithmetic reasoning, and quantitative comparisons. Students identify numerical patterns or determine which quantity is greater — reasoning about numbers, not just computing.

What it tests:

  • ›Number pattern and series recognition
  • ›Quantitative comparison and magnitude reasoning
  • ›Arithmetic reasoning with simple operations

Example question type:

"3, 6, 9, 12, ___ (A) 13 (B) 14 (C) 15 (D) 16"

Prep Timeline

4-Week OLSAT Study Schedule

15–20 minutes per day, 4–5 days per week. OLSAT prep balances vocabulary building (verbal) with visual pattern practice (nonverbal).

1

Week 1

Verbal Foundation

  • ›Learn 5 new vocabulary words daily
  • ›Practice verbal analogies (A:B :: C:?)
  • ›Listening comprehension games
  • ›Category sorting: name words that belong together
2

Week 2

Nonverbal Patterns

  • ›Figure sequences: what comes next?
  • ›Pattern blocks and geometric analogies
  • ›Number series (skip-counting, arithmetic)
  • ›Picture classification activities
3

Week 3

Mixed Practice

  • ›Alternate verbal and nonverbal question sets
  • ›Introduce light time pressure (1 min per 2 questions)
  • ›Focus extra time on weakest subtest
  • ›Practice listening to instructions carefully
4

Week 4

Full Test Simulations

  • ›Complete timed full-length practice tests
  • ›Review errors — understand the reasoning
  • ›Simulate test-day conditions (quiet, timed)
  • ›Rest 2 days before the actual test

Score Interpretation

Understanding OLSAT Scores

OLSAT scores are reported in three formats. Most gifted programs use the percentile or the SAI.

School Ability Index (SAI)

Mean of 100, SD of 16. Similar to an IQ scale. Compares your child to others of the same age. Gifted threshold is typically SAI 120+ (90th percentile).

Below 100

100–119

Average–High

Gifted range

Percentile Rank

Most districts require the 90th–95th percentile for gifted placement. NYC G&T programs are especially competitive. Check your district's specific cutoff.

90th–95th pct

Typical gifted program entry threshold

Stanine Score

A 1–9 scale grouping percentile scores into bands. Stanines 7–9 indicate above-average ability. Used by some districts for initial gifted screening.

Common Questions

Frequently Asked Questions

What is the OLSAT?

The Otis-Lennon School Ability Test (OLSAT) is a group-administered reasoning test published by Pearson. It measures verbal and nonverbal abstract thinking and is widely used for gifted program admissions, especially in New York City.

What grades take the OLSAT?

The OLSAT is administered to students in PreK through grade 12, with seven levels (A–G) aligned to grade. Most gifted screening using the OLSAT happens in PreK–grade 3.

How is the OLSAT different from the NNAT?

The OLSAT tests both verbal and nonverbal reasoning; the NNAT tests only nonverbal reasoning. NYC's gifted program uses both: NNAT for nonverbal and OLSAT for overall ability. The OLSAT takes 40–60 minutes; the NNAT about 30 minutes.

What score is needed for NYC G&T?

For NYC's Gifted and Talented program, students must score at the 90th percentile or above on the combined OLSAT + NNAT composite score. For the most competitive citywide programs (like NEST+m or G&T K), the typical threshold is the 97th–99th percentile.

Can kids prepare for the OLSAT?

Yes. Practice helps children become familiar with the question formats and reduces test anxiety. The verbal portion benefits from vocabulary building and analogy practice; the nonverbal portion benefits from visual pattern work. Start 4–6 weeks before the test.
