Average Share of Students in “Beating the Odds” Schools for 3 Most Recent Years of Data in Math
This measure shows the average share of students in a city enrolled in a school whose proficiency rates outpaced demographically similar schools elsewhere in the state, averaged over the three most recent years of available data. The results come from regression models that use information on all of the schools within a city’s state to predict the proportion of students in a school who score at or above proficiency based on the school’s student demographics and other school characteristics. The results (specifically the residuals) show the difference between a school’s actual proficiency rate and the rate we would predict, given the school’s student composition and other characteristics. We only identified schools as outperforming similar schools statewide when the probability that the residual is zero was less than 5 percent (p < 0.05 in a one-tailed significance test).
