Description
Summary:An exploratory analysis of four large educational data sets found evidence of schools and districts that consistently produced outstanding students, even after socioeconomic factors were controlled for. Like many previous studies, this study used regression analysis of achievement data, but it focused on statistical outliers rather than on central tendencies. Histograms of residuals showed no evidence of extreme overachievers, but comparisons over different years and grades of consistently overachieving schools with the number expected by chance showed some evidence of unusually effective performers. Outstanding Michigan schools had smaller classes, better-paid teachers, and more teachers with greater than five years' experience.
