Since I had the wrong link in the original, I am reporting.

Noel Hammatt is an independent researcher and former board member of the Baton Rouge public school board. He is one of the best-informed and most courageous researchers in a state where truth is to be found not in official statements, which are political, but in the work of bloggers and independent researchers like Hammatt.

This is a great analysis he made of the state’s grading system, in which he asks why schools fail and wonders: what if a failing school is not failing at all?

Here is another link in which Noel writes for a popular audience.
