Kudos to this teacher for highlighting the problem of failing students being giving passing grades – and passed along…

Caleb Stewart Rossiter, a college professor and policy analyst, decided to try teaching math in the D.C. schools. He was given a pre-calculus class with 38 seniors at H.D. Woodson High School. When he discovered that half of them could not handle even second-grade problems, he sought out the teachers who had awarded the passing grades of D in Algebra II, a course that they needed to take his high-level class.

There are many bewildering stories like this in Rossiter's new book, "Ain't

Nobody Be Learnin' Nothin': The Fraud and the Fix for High-Poverty Schools," the best account of public education in the nation's capital I have ever read. It will take me three columns to do justice to his revelations about what is being done to the District's most distracted and least productive students.

Teachers will tell you it is a no-no to ask other teachers why they committed grading malpractice. Rossiter didn't care. Three of the five teachers he sought had left the high-turnover D.C. system, but the two he found were so candid I still can't get their words out of my mind.
