U.S. Charter Schools summarizes an analysis by the National Alliance of Public Charter Schools of a survey of 390 public charter schools as part of the 2005 National Assessment of Educational Progress (NAEP).

According to NAEP, a high proportion of charter school students have a history of academic struggle and begin charter schools below average on state performance assessments.

Charter schools in operation for seven to 10 years outperform schools open for one to five years.

  1. I’m guessing this is due to survival bias, in that unsuccessful charters close down before they hit the 7-year mark.

  2. It’s nice to see that the NEAP confirms what common sense dictates; charter school kids are kids that weren’t doing well in the district school.

    Why anyone would give credence to the charge of cherry-picking after a moment’s thought is as odd as assuming that a responsible parent would pull their kid out of a school they were succeeding in.
