Swing education transforms the way K-12 schools and substitute teachers connect. | Swing Education connects high-quality substitute teachers with schools in need. We recruit, screen, and support a large group of substitute teachers, and we make it easy for schools to find the right sub at the right time. We believe substitute teachers play an integral role in education; after all, the average student spends six months of their K-12 career with a sub.
