While much of the literature regarding college readiness focuses on student-specific factors, such as the individual's academic achievement; scores on college readiness assessments; and high school GPA, more research is needed to understand which school-level factors have the most influence on the percentage of college-ready graduates. The purpose of this research study was to explore the impact of various school-level factors (i.e., student demographics, college entrance exam facts, course offerings, and school characteristics) on the percentage of college ready graduates from Texas public high schools serving Grades 9-12 over a 3-year period. A multiple regression analysis conducted for each year's data resulted in three regression models, which identified various predictors (e.g. per-pupil instructional expenditures, teacher years of experience, taking advanced and/or dual credit coursework) of the percentage of college-ready graduates for schools accounting for 91.7%, 79.5%, and 65.6% of the explained variance in 2013, 2014, and 2015, respectively. Findings from this study provide educational leaders with data that could help them to make better-informed decisions regarding potential college readiness initiatives that, ultimately, could improve student performance.
