Many Extension precollege programs seek to increase young people's interest in and aspirations toward college by fostering the development of skills that support a successful college transition. By pairing existing data with participant enrollment records, Extension professionals can more easily capture the impact of precollege programs on college enrollment and degree attainment. This article summarizes the process a group of us at Michigan State University Extension use to track Michigan 4-H precollege program alumni college enrollment rates, leveraging existing data from the National Student Clearinghouse and the Michigan Department of Education. Our method is a relatively easy and inexpensive way to measure and share precollege program impacts.
