The Growth & Achievement tool depicts performance on STAR Assessments for a hypothetical student, displayed as a trend line of prior scores and a prism representing future growth possibilities. This tool helps address questions such as How is the student performing over time and relative to state proficiency benchmarks? What are the likely growth possibilities for this student? and is similar to the Renaissance Learning Dashboard where districts using STAR have access to real-time data on performance.
The STAR scaled scores displayed on the Y-axis are based on normative data. Selections for student achievement (well above average, above average, average, below average, and well below average) correspond to the 90th, 75th, 50th, 25th, and 10th percentiles, respectively, by grade. A student’s most recent scaled score is represented by the leftmost point on the prism.
The gray background indicates estimated state-test performance-level cut scores by grade for the state selected (based on the 2013–2014 school year), per statistical linking to the STAR Assessments. Because many state proficiency tests are in transition, these levels will be updated as the latest data are released.
Using STAR Student Growth Percentiles (SGPs), the prism’s color bands represent a range of growth outcomes for a student relative to their academic peers (same-grade students with similar pretest scores): GREEN (SGPs of 66 to 95, greater growth than what 66 to 95% of a student’s academic peers would experience), YELLOW (SGPs of 35 to 65, typical growth), and RED (SGPs of 5 to 34, less than typical growth). The trend line preceding the prism represents prior scores for a student’s selected achievement level.
