This document summarizes a presentation on examining longitudinal data to advance institutional effectiveness and student completion. The key findings were that socioeconomic status (SES) is the main factor influencing student achievement outcomes, with low SES resulting in lower outcomes. Resource allocations differ between low and high SES institutions, with low SES schools spending more on administration and student support, and less on instruction. Higher spending on instruction and lower proportional spending on administration and student support relate to better student outcomes. The implications are that SES accounts for most achievement variation, and colleges should focus improvement efforts on the modest area outside SES impacts through establishing internal research institutes to conduct input-environment-output studies using tailored longitudinal data.
