This document is a workbook that describes how youth practitioners, Workforce Investment Act (WIA) entities, policymakers, funders, and others can use the Promising and Effective Practices Network (PEPNet) to improve the field of youth employment and youth development. The workbook begins with an introduction to PEPNet, which is a framework for program improvement and a resource that identifies practices for effective youth programs and organizes them into five broad categories. The following are among the items included in the workbook's five sections: (1) ways practitioners, WIA entities, policymakers, funders, and others can use PEPNet; (2) the PEPNet improvement process for programs (the benefits of participation and an improvement process flowchart); (3) the PEPNet criteria for effective practices (criteria related to purpose and activities, organization and management, youth development, workforce development, and evidence of success); (4) PEPNet self-assessment (using the PEPNet self-assessment; the PEPNet self-assessment questions, the self-assessment matrix, and the PEPNet builder certification form); and (5) PEPNet recognition (the notice of intent to apply, the process to apply for recognition, demonstrating evidence of effectiveness, additional tips, peer review, benefits of recognition). Lists of 13 recommended resources, PEPNet awardees, National Youth Employment Coalition members (NYEC), PEPNet working group, and NYEC executive committee members are appended. (MN)
