First Grade STAR Results There was not a signifcant efect of treatment on 1st grade STAR LIT/READ scores 3 , suggesting that students in the treatment and comparison group demonstrated similar growth from MOY to EOY. Complete output for each model can be found in Appendix 1. Results of t-tests (and their associated efect sizes) comparing growth in MOY averages and EOY averages in STAR LIT/READ scores between the treatment and comparison groups can be found in Table 14. Second Grade STAR Reading Results There was not a signifcant efect of treatment on 2nd grade STAR READ and Estimated ORF STAR READ scores, suggesting that students in the treatment and comparison group demonstrated similar growth from MOY to EOY. Complete output for each model can be found in Appendix 1. Results of t-tests (and their associated efect sizes) comparing growth in MOY averages and EOY averages in STAR READ and Estimated ORF STAR READ scores between the treatment and comparison groups can be found in Table 14. Grades 3 through 5 FAST Results One outcome (FAST ELA), was normally distributed and tested within a hierarchical linear model. The remaining three outcomes (Domain Generes, Domain Inform Text, Domain Prose Poetry) were dichotomous and therefore tested within a hierarchical logistic regression model. There was not a signifcant efect of treatment on grades 3-5 FAST ELA, Domain Genres, Domain Inform Text and Domain Prose Poetry scores, suggesting that students in the treatment and comparison group demonstrated similar growth. The complete output for each model can be found in Appendix 2. Results of t-tests (and their associated efect sizes) comparing growth is in Table 14, as well as comparing EOY averages. Results of t-tests comparing BOY and MOY averages in scores between the treatment and comparison groups can be found in Appendix 5. Grade 3 FAST Results We separated out the third grade students and ran the models for Grades 3-5 with only third grade. There was not a signifcant efect of treatment on third grade FAST ELA, Domain Genres, Domain Inform Text and Domain Prose Poetry scores, suggesting that students in the treatment and control group demonstrated similar growth. Complete output for each model can be found in 3 The Star assessment requires students to shift from the Early Literacy format to the Reading format once students score above 851. All but 12 frst graders shifted from Early Literacy to Reading at the end of the year. According to the Star technical manual (Renaissance Learning, 2022), the scale scores for each test should be considered and treated as a single unifed scale score for analysis purposes.
