Please note: With the transition from the OAKS assessment to the Smarter Balanced assessment, ODE is aware that IEP teams may need guidance in calculating Essential Skills modified cut scores for students working toward a modified diploma. The following steps are intended to assist IEP teams in converting a student’s scores from the OAKS assessment to equate with their scores on the Smarter Balanced assessment in order to arrive at a specific modified cut score for a student:
  • Step 1: Identify the student’s OAKS Math or Reading score and percentile from previous year(s) assessment. Consult the OAKS percentile tables linked below.
  • Step 2: Using the student’s OAKS Math or Reading score and percentile from previous year(s), find the specific content area’s percentile and range of scores within the content area (ELA-Reading or Mathematics) on the Smarter Balanced percentile tables linked above.
  • Step 3: Using the Smarter Balanced percentile and range of scores as well as your district’s protocol, identify the specific “modified cut score” for the student and put this score on the Statewide Assessment page of the student’s IEP.
