What Industry Specific Solutions does

Industry Specific Solutions, founded in 2007 and headquartered in Southfield, Michigan, operates Sub Teacher Source as a legally separate but affiliated LLC providing K-12 substitute teacher staffing services across the United States. The company serves public, private, and charter school districts in all 50 states, having expanded from a regional operation to a national footprint described as serving hundreds of school districts. Its core offering addresses chronic teacher absenteeism and the substitute teacher shortage by recruiting, vetting, credentialing, and placing substitute teachers, while assuming full payroll, compliance, and administrative responsibility on behalf of partner schools.

The company's primary technology asset is a proprietary absence management system that functions as the operational backbone of the service. Schools access the platform from any device to submit substitute requests, while substitute teachers use an online scheduling system to virtually accept assignments and track work history. The platform also automates timesheet generation and approvals, enabling schools to approve and submit weekly timesheets with a single click. This integrated workflow is complemented by a curated network of pre-screened substitutes who receive orientation, classroom management training, and ongoing professional development.

The business operates under a managed services revenue model: school districts pay Sub Teacher Source for staffing services that bundle recruiting, vetting, credentialing, payroll, and compliance, while the company directly pays placed substitutes at rates that vary by state (ranging from approximately $155 per day in lower-pay states up to $260 per day in higher-pay markets such as New Jersey). Go-to-market is executed through a dedicated account manager model with direct enterprise sales relationships to district administrators, supplemented by a self-serve digital application and scheduling flow on the supply (substitute) side. No external funding rounds, ownership changes, or revenue figures were disclosed in the source data.
