Student Growth Percentiles (SGPs)

Student Growth Percentiles (SGPs) represent one powerful way to quantify the learning of individual students over one or more years. Conceptually, SGPs communicate the degree to which a student has learned in a particular domain, compared to a group of academic peers who had a comparable score on the previous test (or multiple previous tests) in that subject. In order to calculate SGPs, students are grouped with academic peers throughout the state who had comparable score patterns on past tests. Students in each academic peer group are then ordered based on their score on the current year test. Each student then receives a percentile rank, compared to their academic peers. Like other percentile scores, SGPs range from 0-99, where a SGP of 50 indicates that the student demonstrated growth in the content area equal or greater to half of students with comparable score histories on that subject-matter test.
