The Growth Model – Student Growth Percentiles (SGPs)
- Student Growth Percentiles (SGPs) complement the MCAS year-by-year test scores. They measure change in achievement over time rather than grade-level achievement results in any one year. Growth scores are available for schools, districts, and students taking the standard MCAS test in grades 4-8 and 10 in English language arts and mathematics.
- Each student’s rate of change is compared to other students with a similar test score history (“academic peers”). Consequently, SGPs provide a way to measure growth at all performance levels.
