Diagnostic Science Assessments for Middle School Teachers are written tests that measure mathematics knowledge in three content domains (Physical Science; Life Science; Earth/Space Science) and across four types of knowledge (Declarative Knowledge; Scientific Inquiry and Procedures; Schematic Knowledge; 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.
25 items (20 multiple-choice and 5 open-response). Participants usually take between 30-50 minutes to complete the assessment, with the bulk of participants taking about 40 minutes.
