This paper describes and compares interests and values measures useful for career assessment and counseling in tech prep and school-to-work programs. The primary source of information for this information is the third edition of "A Counselor's Guide to Career Assessment Instruments" (Kapes, Mastie, and Whitfield 1994). Stated objectives are as follows: (1) provide an overview of contemporary career interests, (2) describe essential characteristics of each of the most prominent instruments, and (3) synthesize the essential characteristic information across instruments to provide a state-of-the-art analysis of career interest and values measures. The 27 instruments included are described and compared on the following set of 14 characteristics: name of instrument, publisher, date of recent edition, intended population, number of scales, homogeneous or empirical keying, normative or ipsative scoring, time to administer, machine or hand scoring availability, computer-based version availability, types of scores reported, cost of individual test, references to reviews, and brief descriptions. These characteristics are provided for the instruments in an extensive table that shows a wide variety of differences among instruments. (YLB)
