INDIANAPOLIS — A bill that would have scrapped Indiana’s A-F grading scale for individual schools has been withdrawn by its sponsor in the Indiana Senate.

Republican Sen. Carlin Yoder of Middlebury pulled the bill Monday before it could be voted on by the full Senate. Yoder says he still wants to have a new school assessment system put in place and will work to have a new proposal developed later in this year’s legislative session.

The Senate Education Committee voted unanimously last week to back replacement of the A-F scale, which was a top campaign issue last year by new Democratic state schools Superintendent Glenda Ritz.

A spokesman for Ritz says she’s disappointed the bill was withdrawn and that she’ll work with legislators on new school accountability standards.
