How Georgia calculates its “growth” measure
School and district growth scores are based on what are called “student growth percentiles.” Essentially, student growth percentiles are calculated for each student in each tested subject by comparing his or her standardized test scores at the end of one year to the performance of other students who had similar test scores to him or her in the past.
Schools and districts are given a “median growth percentile” that offers a sense of how much a typical student at the school grew in a year compared to his or her academic peers.
