It’s no “Juno,” but this video of a Caroline Hoxby talk on charter schools in NYC is well worth watching. Hoxby discusses her evaluation of NYC charter schools, which compares students who win charter lotteries with those enter but don’t win. The charter effect on math scores is .09 standard deviations, while the effect on reading scores is .04 standard deviations (for a year spent in a charter school). Of particular interest in her description of the programmatic differences between these schools, the most central of which is a longer school day and school year. More on this study coming soon.
