The COVID-19 pandemic disrupted teacher candidates' capacity to complete licensure requirements. In response, many states temporarily reduced professional entry requirements to prevent a pandemic-induced teacher shortage. Using mixed methods, we examine the role of the emergency teaching license in Massachusetts, which provided an opportunity for individuals to enter the public school teacher workforce with only a bachelor's degree. Our results show that emergency licenses increased the supply of teachers in two ways by: 1) providing an entry point for individuals who previously wanted to become teachers but could not meet traditional licensure requirements and 2) expanding the pool of individuals interested in the profession. Among those teachers hired with an emergency license, we find that they were substantially more ethnoracially diverse than their peers with traditional licenses, and they overwhelmingly intend to obtain permanent licensure and remain in the profession. These results suggest that rethinking initial entry requirements may be an effective policy tool to increase the supply of teachers, particularly among teachers of color.
