Caroline Hoxby presented findings of her NYC charter school study at the Columbia Business School Social Enterprise Forum.
Study highlights show that making a little progress every year closes achievement and graduation gaps:
*annual gap closing effects are moderately strong *for every year students spend in a charter they are 7% more likely to graduate from high school *attending a charter school for multiple years can close the achievement gap
Hoxby attributes charter success to
*governance (nonprofit + authorizer v school district) *hiring discretion and lack of union work rules *diagnostic assessment *long day (8 v 5.5) and year (192 days v 178) *pay based on performance & duties (not seniority & credentials)
