Reblogged from Diane Ravitch's blog:
Julia Sass Rubin, a professor of public policy in New Jersey, took a close look at the CREDO study of charter schools and made a startling discovery: the press release misrepresents the findings of the study.
It recognized the dramatic demographic differences between the students in public schools and in charter schools ("the traditional public schools it looked at served four and a half times as many students with Limited English Proficiency and one and a half times as many special-needs students as did the charter schools") but ignored the severity of students' disability or language difficulty.
