The Test of Early Mathematics Ability, Third Edition (TEMA-3, Ginsburg & Baroody, 2003), is a standardized, individually administered norm-referenced test of mathematics performance, with norms for children who are 3–8 years old. The test takes about 40 min to administer and is intended to tap both informal and formal mathematics. Informal mathematics involves skills and knowledge typically acquired outside of school, such as counting skills and understanding of relative magnitude (e.g., 7 is more than 3). Formal mathematics involves skills and knowledge that children usually learn in school, such as base ten concepts (e.g., identifying ones, tens, and hundreds in a written numeral) and procedures for adding or subtracting two-digit numbers with regrouping (e.g., calculating the correct answer for 23 + 49 or 60 − 27). It should be noted, however, that the test yields only a comprehensive (total) score, not individual subtest scores for different areas of math.
