Tweaked state grade system tougher, but fair?

Teresa Auch Schultz:

A sample of how local schools would have performed last year had they been Graded by a new model just approved on Wednesday shows mixed results, with more high schools earning an A but more Fs and Ds overall.
According to information released by Tony Walker, a local representative to the Indiana State Board of Education, seven area high schools would have earned an A instead of the C they received under the old grading model. Those include high schools in Munster, Chesterton, Merrillville, Kankakee Valley, Hobart, Highland, Munster and Valparaiso.
Several high schools had complained about the C grades because they were capped at the level after they did not meet Adequate Yearly Progress goals, which are tied to federal No Child Left Behind requirements. However, Indiana was one of 10 states granted on Thursday a waiver from NCLB, meaning Hoosier schools no longer have to include AYP in how they calculate a school’s grade. The new grading system, adopted by ISBOE, replaces NCLB to assess how schools are improving.
