Sub Teacher Source competitors and assessment
Company assessmentDirect peers
- Scoot Education: A substitute teacher and paraprofessional staffing firm serving K-12 schools in multiple U.S. states with a technology-enabled matching platform. Competes head-to-head with STS for charter and public school substitute coverage.
- Source4Teachers: A direct K-12 substitute teacher staffing competitor serving school districts in multiple U.S. states. Mirrors STS's value proposition of providing vetted substitutes, absence management, and dedicated account support to school clients.
- EduStaff: A Michigan-based K-12 staffing organization providing substitute teachers, paraprofessionals, and support staff to school districts. A particularly direct regional competitor given STS's Southfield, MI headquarters and Michigan roots.
- ESS (Educational Staffing Solutions): One of the largest U.S. providers of substitute teacher and support staff staffing to K-12 schools. Operates a similar model to STS, including proprietary absence management technology and a curated sub pool.
- AB Staffing Solutions: A U.S. staffing firm placing substitute teachers, special education staff, and school support personnel in K-12 districts. Overlaps directly with STS's core substitute placement offering across multiple states.
- Kelly Education (Kelly Services): The dedicated K-12 substitute and support staffing arm of Kelly Services, the largest U.S. education staffing firm. Directly competes with STS on substitute teacher placement to public, charter, and private school districts nationwide.
Broad incumbents
- Frontline Education (Frontline Absence Management): A leading provider of K-12 administrative software (HR, SIS, absence management). While not a direct staffing competitor, its absence management platform is the incumbent technology stack many districts use and competes with STS's Online Absence Management System.
- Randstad US (Education division): Global staffing firm with U.S. education staffing capabilities. Competes indirectly with STS in larger districts and via broader workforce services that include substitute teacher coverage as part of multi-service contracts.
Emerging players
- Parallel Learning: A technology-enabled provider of substitute teachers and special education support to K-12 schools. Competes with STS in adjacent use cases, particularly around credentialed and specialized (e.g., special education) subs.
Regional players
- Teachers On Call (A Plus Staffing): A Midwest-focused substitute teacher and support staffing provider. Comparable operating model to STS but with primary geographic concentration in Minnesota/Wisconsin, making it a regional rather than direct overlap competitor.
