This workbook, which is designed primarily for secondary school administrators involved in planning youth apprenticeship programs, explains approaches to youth apprenticeship that have evolved from operation of the Pickens County Youth Apprenticeship Initiative (PCYAI) in Easley, South Carolina. Discussed first are guiding principles regarding the following: youth apprenticeship; tech prep; working structures; standards and portable credentials; insurance, apprentice wages, and labor/union issues; relationship to other types of work-based learning; role of secondary schools, employer sponsors, and postsecondary institutions; and planning youth apprenticeship programs. Presented next is a six-page program planning checklist covering the following items: building interest and setting a direction; developing the program (governance, administration, and budget; school and work-based curricula; guidance and student support services; mentor training and program support activities; and postsecondary oversight and awarding of credentials); and evaluating/expanding the program. Appendixes constituting approximately 75% of the guide contain the following: flowcharts diagramming the Partnership for Academic and Career Education Tech Prep and other apprenticeship program models; insurance and child labor law information; 38-item bibliography of resources and names/addresses of 23 exemplary apprenticeship program sites; PCYAI training agreement; program planning form, budget form; list of PCYAI secondary-level workplace competencies; and tables of contents of PCYAI student and mentor handbooks.
