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.
