The bipartisan panel investigating the Tony Bennett incident of grade fixing concluded he did nothing "nefarious". The changes made to get a benchmark charter school up to an "A" rating were applied across the board and likely even improved the grades of urban schools. FWCS might even have gotten to hang up their "A rated" banners again. But they protested too much. Like with the computer glitches during ISTEP which turned out to have no measurable effect on the scores.
What Bennett did was just ill advised, especially when the education establishment held him in such contempt. So he gave them an opening to denounce testing and grading, which they also despise, while telling us they welcome accountability. Hey, not everyone was socially promoted.
