What Source4Teachers does
Source4Teachers, operating under the brand name ESS, is a Cherry Hill, NJ-based private company founded in 2000 that provides outsourced managed staffing services — primarily substitute teachers, paraprofessionals, and school support staff — to K-12 public school districts across the United States. The company serves more than 1,200 school districts and places approximately 100,000 employees who collectively serve 8.5 million students daily, making it the largest dedicated K-12 substitute staffing operator in the country. Its customer base spans public school districts of widely varying sizes, from small rural systems (e.g., North Clarion County, Hollister R-V) to large urban districts such as the School District of Philadelphia, where it deploys a localized 'Zone Manager' service model with dedicated points of contact per school.
ESS monetizes through multi-year managed services contracts with school districts, with pricing customized per district based on size, scope, and service requirements. Its core technology is a cloud-based absence management and workforce scheduling platform with integrated credentialing and compliance tracking, complemented by two add-on modules: an Absence Software product for tracking and managing substitute scheduling, and a Clinical Services offering for specialized clinical personnel placement. The company's go-to-market combines direct enterprise field sales targeted at K-12 superintendents and procurement teams with a community-driven candidate recruitment engine (job postings, employee referral programs, and local community engagement) that feeds its 100,000-person substitute pool.
The company is led by CEO Kendley Davenport, is privately held with no disclosed parent company, private equity backing, or venture capital investment, and has been recognized as a 2026 USA TODAY Top Workplace and a 2026 Metro Jacksonville Top Workplace. Its operational moat is built on 25+ years of incumbent relationships, scale advantages in sourcing and credentialing, and workflow integration into district operations via the Zone Manager model.
