Arkansas adopted the ACT ASPIRE as their summative assessment in 2015. ACT ASPIRE claimed their assessment results could accurately predict the composite scores on the ACT. The purpose of this study was to determine the relationship between students' scores on the ACT ASPIRE and the ACT for students in the Star City School District, as well as determining if the ACT ASPIRE accurately predicted eleventh grade students' scores on the ACT. The findings revealed a significant relationship between ACT ASPIRE (ninth/tenth) grade scores and ACT scores. There was a significant difference between ninth grade mean scores and tenth grade mean scores for ACT ASPIRE. Further, ACT ASPIRE (ninth/tenth) scores significantly predicted eleventh grade ACT composite scores. [The dissertation citations contained here are published with the permission of ProQuest LLC.
