What is the difference between top comparable and higher performing schools?
top Top comparable schools are identified for one tested grade, subject and year, and are based on their comparability to one school at a time. These schools are the basis for the opportunity gap, which is a measure of performance specific to a particular school for a particular grade, subject and year. Although the higher performing analysis also considers performance in comparison to similar schools, the higher performing analysis has a more mathematical measure of comparability, and these schools demonstrate consistent higher performance across three years of data and all tested grades.
