In response to rising college tuition and student debt over the past three decades, some institutions, localities, and states have implemented a range of tuition-free promise programs to promote college access and success. Programs vary widely in their design features, including eligibility stipulations and award structure. I explore the growing but understudied trend of tying eligibility for a free college program to enrollment in vocationally oriented fields. Using web-scraped data on nine statewide promise programs with program-based eligibility requirements, I describe which programs are and are not eligible and discuss policy considerations for tying program eligibility to academic programs geared toward the workforce. These findings hold important implications for students in their enrollment decisions and labor market trajectories and for public perceptions of the purpose of higher education.
