The Impact of Transition Intervention in High School on Pathways Through College

Objective: In 2009, the Kentucky General Assembly found unacceptable and costly the ongoing high numbers of high school students requiring remediation once they enter higher education. The state passed legislation to better align secondary and college education, establishing a diagnostic cycle that would become its Targeted Interventions (TI) program. Using 11 years of panel data, this study tracked college progression of seven cohorts of students in order to estimate the impacts of this program. Method: Using student-level administrative data from the state of Kentucky that tracks students from high school through college, a difference-in-regression-discontinuity design was used to compare how students just below college readiness benchmarks fared relative to those just above once TI was implemented. Results: The TI program significantly increased the likelihood that students took at least 15 credits during their first term, a key predictive measure for college completion. However, these early effects did not translate into detectable impacts on the likelihood of earning enough credits to graduate from college or likelihood of transfers from a 2-year to a 4-year college. One possible explanation for this pattern is that TI appears to have crowded out other core courses in high school, especially in math, without increasing total instructional time. Findings suggest that the standards used by high schools to judge student progress toward college readiness may be consistent with the skills needed to place out of developmental courses, but not sufficient to better prepare students for college-level instruction. Contributions: To our knowledge, this is the first study to explore how TI shapes longer term college outcomes. The transition curriculum, while helping students avoid the need for college developmental courses, did not help a measurable share of students develop necessary skills to progress through college relative to what they would have otherwise taken. A possible explanation for these findings is that high school-to-college transition interventions that do not increase total instruction time do not sufficiently move the needle on the college preparedness among high school graduates. For states concerned with the number of students entering college deemed not college ready, it appears that high school-to-college transition interventions that supplant instead of supplement regular high school curriculum have a limited scope for impact on long-run college success.
