## Overview

The Test of Mathematical Abilities – Third Edition (TOMA-3; Brown, Cronin, & Bryant, 2012) is a norm-referenced instrument that measures math performance in children aged 8 to 18 years, 11 months. The TOMA-3 can be individually- or group-administered, and is used to identify and quantify mathematical deficits. The four core subtests are Mathematical Symbols and Concepts, Computation, Mathematics in Everyday Life, and Word Problems. A supplemental subtest option identifies each student’s attitude toward math. Together, the TOMA-3 four core subtests yield a composite score, the Mathematical Ability Index.

## Summary

**Age:** 8 years 0 months to 18 years 11 months

**Time to Administer:** 60-90 minutes

**Method of Administration:** Individual or group administered, norm-referenced measure of math performance.

Yields standard scores (M = 100, SD = 15), percentile ranks, age/grade equivalents.

**Subscales:** OVERALL COMPOSITE: Mathematical Ability Index

SUBTESTS: Mathematical Symbols and Concepts, Computation, Mathematics in Everyday Life, Word Problems; Attitude Toward Math (supplemental subtest) Yields a Mathematical Index.
