U.S. Air Force enlisted professional military education taught lead­ership development courses in a facilitated online format for the first time in the program’s history during the COVID-19 pandem­ic. This cross-sectional, quasi-experimental study collected and analyzed 12 months of data from three of the largest Airman lead­ership schools globally. This study examined students from near­ly all enlisted Air Force specialties (n = 1,183). Comparing pro­cess, demographic, and student learning data from six months of in-person and six months of online instruction, independent sam­ples t-tests revealed students generally earned significantly higher grades in online classes than in person. Course length and student travel costs were the same for both course types. Instructors took as long or longer to complete initial instructor qualification train­ing when teaching online compared to teaching in-person courses. The switch to online instruction eliminated disciplinary disenroll­ments. Military decision-makers can utilize these data when con­sidering the benefits of continuing to conduct professional military education in online learning environments.
