Diagnostic Teacher Assessment in Mathematics and Science (DTAMS): Middle Mathematics Teacher Assessments

Search and Filter

Diagnostic Mathematics Assessments for Middle School Teachers are written tests that measure mathematics knowledge in four content domains (Number/Computation, Geometry/Measurement, Probability/Statistics, Algebraic Ideas) and across four types of knowledge (Memorized Knowledge; Conceptual Understanding; Problem Solving/ Reasoning; and Pedagogical Content Knowledge). Researchers, professional development providers, and course instructors can administer the assessments as pre- and post-tests before and after workshops, institutes, or courses to determine growth in teachers' content knowledge. Multiple parallel versions of each assessment are available.
