The purpose of the study was twofold. The first purpose of the study was to determine if a correlation existed between the Standardized Test for the Assessment of Reading (STAR), created and distributed by Renaissance, and the Tennessee Comprehensive Assessment Program (TCAP) Achievement Test in Math and Reading for grade 3, grade 4, and grade 5. The second purpose of this study was to evaluate the relationship between the percentile category of the STAR test and the TCAP test. The factor variable, identified as the percentile category, included three levels: Urgent Intervention, Intervention, and At/Beyond Benchmark. The dependent variable was the TCAP score. The study included 3rd-grade, 4th-grade, and 5th-grade students during the 2016--2017 school year who had taken the STAR reading and STAR math assessments and had taken the TCAP reading and TCAP math assessment.

Based on the findings of this study, a strong correlational relationship does exist between the STAR and TCAP assessments. Overall, the strong correlation between the STAR and the TCAP were consistent across Math and Reading in 3rd, 4th, and 5th grades. Since the ANOVA was significant, a post hoc multiple comparisons was conducted to evaluate pairwise difference among the means of the three groups. Overall, the At/Beyond Benchmark group was significantly higher than both the Urgent Intervention group and the Intervention group in Math and Reading for 3rd grade, 4th grade, and 5th grade. There was not a significant difference between the Urgent Intervention group and the Intervention group, the exception was 5th grade math.
