FREE OLSAT Study Guide 2026: The Otis-Lennon School Ability Test

This free OLSAT study guide teaches the Otis-Lennon School Ability Test — the group-administered Pearson test that measures the verbal and nonverbal reasoning abilities tied to success in school.^[1] It is used from kindergarten through grade 12, most often to help identify students for gifted and talented programs.

It’s interactive, not a wall of text: every reasoning area has a built-in checkpoint quiz, hover-able glossary terms, worked examples, labeled diagrams, and concept questions, so a child (or a parent helping them prepare) learns by doing.

Work through the four question-type modules, test yourself at each checkpoint, then round out your free OLSAT prep with our practice questions and flashcards. Deciding between tests? See how the OLSAT compares with the CogAT.

OLSAT Exam Snapshot

The most important thing to understand is what the OLSAT is not: it is not an achievement test of facts learned in a grade. It is a reasoning test — “a general ability indicator” that “projects how well the student is able to learn.”^[1] That is why programs use it to spot students ready for advanced instruction.

This guide teaches all five areas, grouped into four study modulesthat match the four kinds of questions you’ll practice: Verbal Comprehension and Verbal Reasoning (the Verbal cluster), then Figural & Pictorial Reasoning and Quantitative Reasoning (the Nonverbal cluster). The Verbal and Nonverbal items are split roughly evenly on most levels:

On most levels the OLSAT is built with about half verbal and half nonverbal items, so a strong score needs both language reasoning and picture/number reasoning.^[2] Reporting the two clusters separately is useful: a child still building English vocabulary can show high reasoning ability through the Nonverbal score.

1 · Verbal Comprehension

Verbal Comprehension is about understanding language. Its four item types — Following Directions, Antonyms, Sentence Completion, and Sentence Arrangement — test whether a child grasps word meanings and how sentences fit together.^[2]The formats below cover almost every Verbal Comprehension item you’ll see.

Antonyms & word meaning

An antonym item asks for the word that means the opposite of a given word. The skill is to decide what the opposite should be before reading the choices, then rule out synonyms and unrelated words. The near-synonym is the classic trap.

Sentence completion & following directions

A sentence-completion item gives a sentence with a missing word; you pick the choice that fits both the meaning and the grammar. Read the whole sentence and predict the word first — the surrounding words are context clues. Following-directions items ask a child to listen to or read instructions and mark the answer that follows them exactly, rewarding careful attention.

Sentence arrangement

Sentence-arrangement items scramble the words of a sentence and ask the child to reorder them (or to pick the word that should come first). Anchor on the subject and verb, then build the rest of the sentence around them; the small connecting words fall into place last.

2 · Verbal Reasoning

Verbal Reasoning is about thinking with language, not just understanding it. Its seven item types — aural reasoning, arithmetic reasoning, logical selection, the word/letter matrix, verbal analogies, verbal classification, and inference — ask a child to find relationships and draw conclusions.^[2] These items are the heart of the OLSAT.

Verbal analogies & classification

A verbal analogy takes the form A is to B as C is to ? Name the relationship in the first pair, then apply the very same relationship to the second pair before you look at the choices.

A verbal classification item asks which word does not belong: in maple, oak, pine, granite, three are trees and granite is a rock, so granite is the odd one out. Name the shared category of three words, and the outlier becomes obvious.

Logical selection & inference

A logical selection item asks which property must always be true of something — every island must have water all around it; it need not have palm trees. An inference item gives facts assumed true and asks what follows. The discipline is to accept only what the statements prove.

Arithmetic & aural reasoning

Arithmetic reasoning items are word problems you translate into a quick calculation — they sit in Verbal Reasoning because the challenge is reasoning about a situation, not heavy computation. Aural reasoning items (common on lower levels) read a short scenario aloud and ask the child to reason to a conclusion.

3 · Figural & Pictorial Reasoning

The nonverbal items reason with pictures and shapes instead of words. Figural Reasoning uses abstract figures; Pictorial Reasoning uses everyday pictures and appears only on the lower levels (grades K–2). Both work the same way — find the rule, then apply it.^[2]

Figural classification & analogies

A figural classification item shows several figures and asks for the odd one out — the one that breaks a shared property (shape, shading, size, orientation, or number of parts). A figural analogy reads figure A is to figure B as figure C is to ? — spot the single change from A to B, then apply it to C.

Pattern matrices

A pattern matrix is a 3-by-3 grid of figures with one empty cell. Read how the figures change across each row and down each column, then find the figure that satisfies both directions at once. Solve one direction first, then use the other to confirm a single answer.

Figural series

A figural series shows a row of pictures that change step by step. Find what changes — the count of parts, a rotation, the shading, or the size — then continue that exact change one more step. If a shape has 1, 3, 5, then 7 holes, the next has 9 holes.

4 · Quantitative Reasoning

Quantitative Reasoning reasons with numbers. Its three item types — Number Series, Numeric Inference, and Number Matrix — ask a child to find a hidden numerical rule and extend it.^[2] These items reward pattern-finding and clean mental math, not heavy computation.

Number series & numeric inference

A number series follows a hidden rule and asks for the next term. Test for a constant difference (an arithmetic sequence) first, then a constant multiplier (a geometric sequence); if neither fits, look for a growing gap, square numbers, or a two-step rule.

A numeric inference item gives number pairs or groups that share one hidden rule; find the rule and supply the missing value. For (3, 12), (5, 20), (7, ?), each second number is the first times 4, so the answer is 28.

Number matrices

A number matrix is a grid of numbers with one cell empty. Find how each row changes left to right (or how each column changes top to bottom), then apply that rule to the row or column with the blank.

OLSAT Scores Explained (SAI)

The OLSAT’s main result is the School Ability Index (SAI) — an age-based standard score normalized to a mean of 100 and a standard deviation of 16.^[3] Because a child is compared to others the same age(not grade), a younger student in a grade isn’t penalized for being young. The OLSAT reports a Total SAI plus separate Verbal and Nonverbal scores.

Alongside the SAI, the OLSAT reports a percentile rank, a stanine (1–9), and a Normal Curve Equivalent.^[1] There is no pass or fail: the OLSAT is a norm-referenced testthat shows where a child ranks among peers. Whether a score qualifies for a gifted program depends on each district’s cutoff — often around the 95th–98th percentile, but set locally, and usually combined with other measures.

How to Use This Study Guide

A study guide is a map, not the whole territory — use it alongside practice and our free tools. The OLSAT measures reasoning, so the goal of prep isn’t to memorize answers but to make every item format instantly familiar, so a child spends test time thinking, not decoding the directions.

OLSAT Glossary

Quick definitions for the terms you’ll see most across the OLSAT:

Antonym

A word that means the opposite of another word (ancient / modern). OLSAT Verbal Comprehension includes antonym items.

Arithmetic sequence

A number series with a constant difference between terms, such as 7, 14, 21, 28 (adding 7 each time).

CogAT

The Cognitive Abilities Test, published by Riverside Insights — a different ability test that reports three separate batteries (Verbal, Quantitative, Nonverbal), unlike the OLSAT's two clusters.

Figural analogy

A nonverbal item: figure A is to figure B as figure C is to ? — find the change that turns the first figure into the second, then apply it to the third.

Figural Reasoning

An OLSAT nonverbal area using shapes and abstract figures: Figural Classification, Figural Analogies, Pattern Matrix, and Figural Series.

Figural series

A row of figures that change step by step; find the rule of change and continue it one more step.

Geometric sequence

A number series with a constant multiplier between terms, such as 2, 4, 8, 16 (multiplying by 2 each time).

Inference

A conclusion you can reach using only the facts you are given; if the facts don't establish it, the answer is that it cannot be determined.

Logical selection

An item asking which property must always be true of something — a forest must always have trees, but need not have a river.

Nonverbal cluster

One of the OLSAT's two score clusters; it combines the Pictorial Reasoning (lower levels), Figural Reasoning, and Quantitative Reasoning areas — items built from pictures, shapes, and numbers.

Norm-referenced test

A test scored by comparing a student to a representative sample of peers, rather than against a fixed passing mark. The OLSAT is norm-referenced.

Normal Curve Equivalent (NCE)

A normalized score from 1 to 99 (mean 50) with equal intervals, useful for comparing or averaging scores — reported by the OLSAT.

Number series

A row of numbers that follows a hidden rule; you find the rule and give the next term (4, 8, 12, 16 → 20).

Numeric inference

A quantitative item giving number pairs or groups that share a hidden rule; you find the rule and supply the missing value.

OLSAT

The Otis-Lennon School Ability Test — a group-administered test, published by Pearson, that measures the verbal and nonverbal reasoning abilities related to success in school. The current version is the Eighth Edition (OLSAT 8).

OLSAT levels (A–G)

Seven grade-based forms: Level A = kindergarten, B = grade 1, C = grade 2, D = grade 3, E = grades 4–5, F = grades 6–8, G = grades 9–12.

Pattern Matrix

A figural item showing a 3-by-3 grid of shapes with one empty cell; you use the patterns across the rows and down the columns to choose the missing figure.

Percentile rank

The percentage of same-age children a student scored as well as or better than. A 95th percentile means scoring at or above 95% of peers.

Pictorial Reasoning

An OLSAT nonverbal area used only on the lower levels (grades K–2): Picture Classification, Picture Analogies, and Picture Series, built from everyday pictures young children recognize.

Quantitative Reasoning

An OLSAT nonverbal area using numbers: Number Series, Numeric Inference, and Number Matrix items.

School Ability Index (SAI)

The OLSAT's age-based standard score, normalized to a mean of 100 and a standard deviation of 16. It compares a child to others the same age; the OLSAT reports a Total, a Verbal, and a Nonverbal SAI.

Stanine

A score from 1 to 9 that groups percentile ranks into nine bands (5 is average). The OLSAT can report a stanine alongside the SAI.

Synonym

A word that has nearly the same meaning as another word (happy / glad).

Verbal analogy

A verbal item in the form A is to B as C is to ? — find the relationship in the first pair and apply it to the second.

Verbal classification

A 'which one doesn't belong' item: three words share a category and one does not (maple, oak, pine, granite → granite).

Verbal cluster

One of the OLSAT's two score clusters; it combines the Verbal Comprehension and Verbal Reasoning areas — the language-based items.

Verbal Comprehension

An OLSAT verbal area covering Following Directions, Antonyms, Sentence Completion, and Sentence Arrangement — understanding language.

Verbal Reasoning

An OLSAT verbal area covering aural reasoning, arithmetic reasoning, logical selection, the word/letter matrix, verbal analogies, verbal classification, and inference — reasoning with language.
