Back in mid-May, teacher Todd Friedman’s disciplinary action hit the news because of what it was regarding: He bought 102 copies of Mary Shelley’s Frankenstein for his AP students out of his own pocket and sold them to students for $2 a piece, less than he paid. But staff got wind of the deal, and Principal Michael McDonnell filed a formal complaint.

In a DOE investigation, the office of Special Investigations found that Friedman had broken a minor regulation about teachers selling to students, and he was put on administrative duty with possible firing on the line.

At the time, Friedman noted that not a single student had made a complaint, since his $2 copies of Frankenstein were cheaper than the $6 edition of Hamlet the same students had been required to buy from the school bookstore.

Friedman also implied that the suspension was less about the book and more about his filing unfair-labor charges about the way the school did teacher evaluations last year.

But there’s good news, too. After media coverage and student outcry brought attention to his issue, the Department of Education has dropped all charges of misconduct. He will return to proctoring exams before the end of the school year and will return to teaching all of his classes at Midwood High School next school year.
