The Montana Early Childhood Apprenticeship Program (MECAP) aims to support and increase retention of early childhood education (ECE) providers through on-the-job training, mentorship, and college coursework. Upon completing the program, apprentices are awarded the Child Care Development Specialist Certificate from Montana's Department of Labor and Industry and reach Level 4 of the Montana Practitioner Registry. MECAP is a Registered Apprenticeship Program (RAP). A RAP is a government-run, on-the-job, paid training program model that is validated through the U.S. Department of Labor or a state agency. Traditionally, RAPs have been developed to support a range of industries and occupations across the country, including skilled trade-related occupations (e.g., electricians or carpenters).
