Student Growth Percentiles (SGP)

A student growth percentile (SGP) describes a student’s growth compared to other students with similar prior test scores (their academic peers). Although the calculations for SGPs are complex, information can be shared in percentile terms that are familiar to most teachers and parents. This site provides an overview of student growth percentiles, a new method of measuring student academic growth introduced by OSPI in March 2013.
