IRAPs are high-quality apprenticeship programs recognized by industry and/or workforce leaders known as SREs. IRAPs were designed to give the additional flexibility necessary to expand the apprenticeship model and to address the diverse workforce needs of different industries and occupations. A RAP is a proven model of apprenticeship that has been validated by the Department of Labor or State Apprenticeship Agency. RAPs are known for their structure, rigor, and quality and are designed for organizations interested in receiving the DOL or state seal of approval and funding opportunities made available by DOL. The U.S. Department of Labor has created a helpful side-by-side document comparing the two programs.
