This document provides case studies of three different market-driven youth workforce development projects to demonstrate the variety of scale-up strategies and models available. Rather than be a step-by-step guide, this technical note describes the experiences of the three initiatives and offers examples and lessons learned. The study of each project has a brief description of the program; gives the rationale for the scale-up strategy selected; and discusses the scale-up activity, sharing challenges and approaches for staying market-driven. In addition, the discussions include specific recommendations drawn from each project’s experience.
