Some fact-checking is in order, and the place to start is with the film’s quiet acknowledgment that only one in five charter schools is able to get the “amazing results” that it celebrates. Nothing more is said about this astonishing statistic. It is drawn from a national study of charter schools by Stanford economist Margaret Raymond (the wife of Hanushek). Known as the CREDO study, it evaluated student progress on math tests in half the nation’s five thousand charter schools and concluded that 17 percent were superior to a matched traditional public school.

Pretty good analysis of charter schools.
