This guide describes a collaborative approach to high quality and relevant evaluation of a workplace basic skills program that can be carried out as part of normal program operations. It is designed for use by educators, union representatives, managers, supervisors, participating employees, and funders. The guide is organized into five phases. In each phase, the reader is presented with a series of steps and activities for an evaluation team to undertake. In phase I, the reader is provided with materials for the first two steps: to prepare for the role as facilitator of a collaborative evaluation process and to organize the team. Phase II covers planning a first round of evaluation activities through these four steps: identify who wants what information for what purpose, clarify program goals and indicators to examine in the summative evaluation, identify program components and quality standards to examine in the formative evaluation, and decide how to collect the information. Phase III provides materials for three steps in preparing to gather information: design information-gathering activities, field test instruments, and develop an action plan. Phase IV covers three steps in gathering, organizing, analyzing, and reporting information: gather and organize information, analyze the information and prepare a report, and report findings. Phase V focuses on two steps: take follow-up action and evaluate the evaluation. A bibliography lists 21 suggested readings. (YLB)
