This document outlines the processes and outcomes of a research project conducted to review work skills analysis tools (products and/or services) that profile required job skills and/or assess individuals' acquired skills. The document begins with a brief literature review and discussion of pertinent terminology. Presented next is a list of comparison criteria that was created by the project advisory committee and refined as the project progressed. The evaluation criteria are grouped into 10 categories: competencies (skills, knowledge, abilities) assessed by the product and/or service; producer, provider, or supplier; intended consumer; nature of the product or service; target "individual"; nature of the content; format(s) of the product or service; individual(s) involved in doing assessments; total time required; and total cost. Next, the criteria are applied to three types of tools: work skill analysis tools (Advance Skill Command, Portfolio Builder and Assessment System, SkillScape Skills Management, SkillView Power Builder Skill Inventory, and Work Keys); job skills profiling tools (Essential Skills Profile, Workplace Basic Skills Inventory); and individual assessment tools (Workplace Learning Systems, Workplace Success Skills). The report contains 25 references. Appended are the following: project advisory committee members list, sample skills lists; and initial list of work skills analysis tools.(MN)
