The increased attention to measuring career skills has resulted in more instrument development, more testing of students, and more test administrators. There are three key areas of concern. The first area is that of identifying purposes to be served by assessing career skills. Purposes include permitting descriptions of the current status of individuals or groups, and evaluation (effectiveness, utilization in program improvement, allocation of resources, and allocation of money). The second area is that of becoming an informed user of career skills tests--Is the instrument designed for the test audience?; Is the reading level appropriate?; Is the test reliable?; Is it valid?; and Is it free of sexual and cultural stereotyping? The third area concerns limitations in test design and use. There are two principal concerns about the design of paper and pencil career skills assessment materials. They are (1) indirect measurement and the problem of sampling in assessing career skills, and (2) the effects of verbal ability on student performance on measures of career skills. Appropriate caution should be observed in using tests of career skills. (CT)
