Tennessee charters have learned the secret to high test scores: push out low-performing students right before testing time.

That way, the charter keeps the money, and the public school gets the low score.

This is not a closely guarded secret, but it usually fools the media and the politicians.

Here is one journalist–Dennis Ferrier at WSMV–who was not fooled:

“When it comes to the net loss of students this year, charter schools are the top eight losers of students.

“In fact, the only schools that have net losses of 10 to 33 percent are charter schools.”

The KIPP school in Nashville has an attrition rate of 18%.
