Ohio's Department of Education and Workforce says districts must give mathematics diagnostic assessments to students in kindergarten through third grade beginning with the 2026-2027 school year. A Sept. 10 department bulletin directs districts to its implementation guidance.

The department's Math Diagnostic Assessments webpage describes the test as a universal screener used to identify whether students are on track with their grade-level mathematics content. That guidance lists Sept. 30 as the annual administration deadline.

The webpage also provides approved assessment options and vendor-specific scoring information, along with resources for educators. Districts should consult the full department guidance for implementation details rather than rely on the short bulletin alone.
