INDIANAPOLIS (AP) — Indiana schools Superintendent Glenda Ritz is asking the state Board of Education to not give lower A-F grades to schools for a year because of an expected drop in student standardized test scores.

Ritz gave board members a proposal Wednesday that would give individual schools an updated A-F grade only if it was improved from the previous year. She cites an anticipated score decline with changes to the ISTEP exam taken this spring and wants schools to have more transition time.

Ritz is a Democrat who’s been skeptical of the school grading system, while the board dominated by Republican Gov. Mike Pence’s appointees has advocated the grades.

The board isn’t expected to decide on the proposal until this fall.
