About Sub Teacher Source
Sub Teacher Source is a national educational staffing partner connecting qualified substitute teachers and schools across public, private, and charter education.
Through our state-of-the-art absence management platform, we simplify the process of connecting schools and substitute educators, managing assignments and time sheets, facilitating substitute payments, and supporting required compliance reporting.
Originally created by Industry Specific Solutions, STS now operates as a legally separate but affiliated LLC specializing exclusively in substitute teacher staffing. Our team understands the unique challenges schools face when managing daily staffing needs, and we work closely with public and charter school districts to provide dependable, responsive, and high-quality substitute staffing solutions.
Today, STS proudly partners with hundreds of school districts across multiple states. Our mission is to build strong, lasting relationships with the districts we serve while connecting talented substitute educators with schools where they can have a meaningful impact. As we continue to grow, our vision is to expand our services throughout the United States and ultimately become a leading international educational staffing organization.

The reliability and quality of subs has filled a need that had been lacking for years. Your service allows us to not have to worry about an area that caused a lot of stress and took away from our own staffing that had to cover these absences.
