The implementation of education policies requiring the turnaround of persistently low-achieving schools has demanded reforms that will not only improve achievement, but also deliver results in a short period of time. To meet such demands, Jefferson County Public Schools educators implemented Project Proficiency (PP). Results from state-administered mathematics tests demonstrated that all participating schools reported substantial increases in student proficiency. We examined the impact of PP on the performance of students, who met dropout predictive criteria established by Balfanz, Herzog, and MacIver. Study results suggested that PP students at risk of dropout realized meaningful and statistically significant achievement gains.
