Test of Mathematical Abilities for Gifted Students–Second Edition (TOMAGS-2)

Ages: Grades 1–6
Time: 30 to 60 minutes
Administration: Individual or group

The Test of Mathematical Abilities for Gifted Students–Second Edition (TOMAGS-2) is a standardised, norm-referenced test used to identify students in Grades 1 through 6 who are gifted in mathematics.

Specifically, the TOMAGS-2 measures students’ ability to use mathematical reasoning and problem solving.

The second edition now has three levels: the Primary level for Grades 1 and 2, the Intermediate level for Grades 3 and 4, and the new Advanced level for Grades 5 and 6.

New Features

• An all-new demographically representative standardisation sample was collected in 2014–2018.
• Only one set of norms for general education students (which includes a small percentage of students with exceptionalities and disabilities) is reported.
• New studies of the floors, ceilings, and item gradients index scores are included.
• New studies of test bias (both differential item functioning and subgroup comparison studies) indicated that the test possesses little or no bias in regard to gender, race, or ethnicity.
• New reliability and validity studies, including diagnostic accuracy analyses were done. These analyses involve the computation of sensitivity and specificity indexes and the receiver operating characteristic/area under the curve (ROC/AUC) statistic.
