One of the disturbing behaviors of charter chains is their boasting. All too often, when someone looks past the press release, they find data games, fudging of the numbers, or falsehoods.

Jonathan Pelto, a former legislator who follows Connecticut politics and concentrates on education, says that the boasts of a major charter chain in that state are hollow.

Achievement First, a much-touted charter chain, boasts of that 100% of its graduates are accepted into college.

But Pelto cites a new report showing that the number who graduate and enroll in college is far lower because of attrition.

Stefan Pryor, the state education commissioner, was a co-founder of Achievement First.
