Diagnostic Assessments

Ohio’s diagnostic assessments are aligned to Ohio’s Learning Standards. The primary purpose of the diagnostic assessments is to provide a tool to check the progress of students toward meeting the standards. The diagnostic assessments were developed in two formats:

  • Screener:  measures beginning year skills
  • Full Measure:  measures end-of-year skills

Based on the Third Grade Reading Guarantee, districts/schools must administer a reading diagnostic assessment to all students in kindergarten through grade three by September 30 of each school year to meet the requirements of the Third Grade Reading Guarantee. Districts have the option of using the state-developed diagnostics or a vendor assessment on the department’s approved list of diagnostic assessments.  Districts who use the state-developed diagnostics must print the assessments locally. 

Districts/schools must administer a mathematics diagnostic assessment to all students in grades one and two, and a writing diagnostic assessment to all students in grades one, two, and three at least once during the school year. 

A district's/community school's ability to use a vendor diagnostic assessment for writing and mathematics is contingent on the previous year's letter grades for the categories Performance Index and Value-Added. If a district earned an "A" or "B" grade in Performance Index or Value-Added on the previous year's report card, then the district may use a vendor diagnostic assessment. All results must be reported into EMIS. Student results will be reported as on-track and not on-track.  (Note: On the Student Score Sheet, students who score in the category of "further assessment may be needed" is considered "on track". However, it is strongly encouraged to provide interventions to these students.)
