This document summarizes the roles in the NITAS apprenticeship system. It describes that NITAS is administered by CompTIA on behalf of the IT industry. The US Department of Labor recognizes apprentices who complete the program. Employers can register as NITAS sponsors to implement apprenticeship programs. Sponsors provide on-the-job learning for apprentices under coaches/mentors and track their progress online. The system connects apprentices, sponsors, consultants, and content providers to support IT apprenticeships.
