Investment Rating - The report does not provide a specific investment rating for the industry Core Insights - The study indicates that ACT composite scores (ACTC) are often better predictors of first-year college GPA (FYGPA) and degree completion for students who received accommodations during the ACT exam compared to high school GPA (HSGPA) [1][4] - The correlation between ACTC and FYGPA is higher for students with accommodations, while the opposite is true for those without accommodations [1][4] - The findings challenge existing literature that typically suggests HSGPA has a slightly higher correlation with FYGPA than standardized test scores [1][4] Summary by Sections Correlation Analysis - The report presents a correlation analysis showing that for the overall group of 143,768 students, the correlation coefficients are as follows: ACTC to HSGPA at 0.54, ACTC to FYGPA at 0.43, and HSGPA to FYGPA at 0.48 [2] - For students with accommodations, the correlation between ACTC and FYGPA is 0.32, while for those without accommodations, it is 0.55 [2] Importance of Findings - The significance of ACT scores and HSGPA lies in their use as benchmarks for academic achievement, influencing decisions made by students, parents, educators, and policymakers regarding college readiness [4] - The report emphasizes the need to understand the differences in predictive validity between HSGPA and ACT scores, especially for students receiving accommodations [4] Further Analysis - The report includes a graphical representation of average HSGPA scores against ACT composite scores for students in both four-year and two-year institutions, highlighting that students with accommodations show a flatter slope, indicating less differentiation in HSGPA across ACT scores [5][9] - The analysis reveals that the gap in HSGPA between students with different ACT scores is smaller for those receiving accommodations compared to those without [9]
