The Advantages of Star Assessments


Comprehensive reporting


Interactive data visualizations provide leaders with an enhanced view of Star’s district reporting for more powerful insights. Dig deeper into your data than ever before using Renaissance Analytics’ multiple filters, demographic comparisons, and longitudinal views.


Make the most of instructional time by knowing who is performing above or at benchmark and who may need additional support or intervention. See valid, reliable data immediately after testing.

Know how students are performing against school, district, or state benchmarks so you can prioritize needs and allocate resources more effectively.

Set goals

Take the guesswork out of setting the right goals to motivate and engage every student. An embedded, research-based goal-setting tool helps teachers set reasonable, attainable goals.

Confidently move students forward with a goal-setting tool complete with step-by-step directions and an intuitive user interface.

Monitor progress

Monitor students’ progress toward goals throughout the school year. Know if students in RTI/MTSS are responding to intervention in time to adjust instruction.

See which students are meeting their goals and determine if students are responding to intervention with easy-to-interpret reports.

Track standards mastery

See who is on track to perform well on your state’s summative assessments. Renaissance dashboards show a unified measure of skill mastery based on your state’s standards.

Data from Star Assessments, along with instruction and practice activities, combine to provide a single, comprehensive view of student progress and growth.

Predict performance

Imagine no more surprises on high-stakes tests! Star Assessments, statistically linked to each state’s summative test, are highly accurate predictors of students’ performance.

State performance reports show which students may be at risk for not meeting state proficiency requirements in time to adjust instruction.

See student growth

Monitor achievement and growth with one report. Student Growth Percentile (SGP) scores show you precisely how much students are growing, showcasing changes in scores between testing events.

Knowing scores increased is not enough. The Star Growth Report uses growth norms and SGP to show if growth was below, above, or on par with expectations.
