This handbook leads the reader through planning and conducting the collaborative evaluation of a workplace development initiative. A glossary is followed by an introduction that addresses the rationale for collaborative evaluation, values and characteristics, using the handbook in one's own situation, and optimum conditions for collaborative evaluation. The handbook is divided into sections addressing the four phases of collaborative evaluation. Each phase consists of two to seven steps. Phase 1 covers preparing to facilitate and organizing the committee. Steps 1 and 2 are to do one's homework and organize the evaluation committee. Phase 2 on planning the evaluation consists of seven steps: clarify members' expectations, clarify goals, identify audiences, plan for monitoring, design monitoring activities, test monitoring activities, and finalize evaluation schedule. Phase 3 is related to gathering, organizing, interpreting, and reporting a first round of information. The four steps are as follows: gather and organize the information, interpret the information, plan and make one's presentation, and report one's findings. Phase 4 is to decide what happens next. The final two steps are to take follow-up action and evaluate type of evaluation. Each step discusses what the reader should do and provides activities. An annotated select bibliography contains 36 entries in two categories: trends and issues as well as evaluation and needs assessment. (YLB)
