Substitute Teacher Service

Substitute Teacher Service Welcome to STS - your top choice for substitute teachers, aides, and support personnel in Pennsylvania. Connect with us to elevate your school community today!

Count on us for quality education solutions tailored to your district's needs. Substitute Teacher Service, Inc. recruits educational professionals throughout the spectrum from newly graduated teachers to retirees who serve as substitute teachers in the Pennsylvania and Delaware state school districts that we service. Our recruiting efforts place over 5,000 teaching professionals on our list at any

given time. STS works in conjunction with the Departments of Education to assure that the professional staff we hire meet all of the requirements necessary for teaching in the state. The management team of Substitute Teacher Service has over thirty years experience in the temporary industry. Our expertise and recruiting practices in conjunction with employee retention gives us the competitive edge over other staffing agencies of this type. STS conducts business in the greater Delaware Valley area from it's headquarters in Media, Pennsylvania, with branch offices in Lancaster, Pennsylvania. We also maintain satellite personnel offices located in Downingtown, Horsham, Oxford, Reading and York, Pennsylvania. Our service offices are open 5 days a week, Monday through Friday afternoon from 9:00 a.m. until 4:30 p.m. When office staff is not available, our digital call processing systems take over via an automated attendant. Aesop is the online absence management system of choice and is available to clients and substitutes 24 X 7 X 365. STS examined the way different school districts handle their need for substitute teachers. We know that if we apply the same principles of recruitment and retention that have made our temporary business a success, we can provide a workable, cost-effective solution in supplying your school district with qualified substitute teachers.
