Achievement indicates whether performance is below, above, or on par with grade-level expectations.
Growth explains the kind of progress the student is making over time. Student Growth Percentile is a method of characterising and measuring growth used in Renaissance Star Reading.
Student Growth Percentile provides context to understand how a student has grown by comparing their growth with their academic peers’ growth.
These peers include students in the same grade, and those who started with a similar scaled score and history of performance.
On the Growth Proficiency Chart, teachers can compare individual students’ growth and achievement with peers.
Student Growth Percentile (SGP) is determined by first calculating growth between current test scores and up to two previous scores, then comparing that calculation to the growth of academic peers.
Each time a student completes a Star Reading, an SGP is generated.
