This booklet provides an introduction to evaluating a work force training program, both to assess its impact and to improve its effectiveness. The guide provides instructions for assessing a single training program, rather than a training department in a company or a training provider. It is targeted at small and midsized companies and the providers that serve them (such as community colleges). The guide is organized in four sections. The first section lays out the entire training process and identifies how and where this guide can help in that process. The second section provides an introduction that defines evaluation and explains its value. The third section presents 10 steps for designing and implementing a training evaluation: establish provider-customer relationship, gain key stakeholder involvement, identify training goals and objectives, specify outcomes, examine inputs and processes, identify data required, collect data, analyze data, interpret data, and use and report data. The fourth section of three appendixes contains the following: (1) an annotated list of 14 training evaluation resources; (2) lists of the National Workforce Assistance Collaborative's board and councils; and (3) lists of the collaborative's products and services.
