The Career Decision-Making Course was designed to help students develop the decisional attitudes and competencies that increase readiness to deal with career-choice tasks and facilitate behavioral responses that meet these tasks. The course addresses career-choice process and content by using the teach-the-test method with Career Maturity Inventory materials. After describing the course, the current article reports the results for a field test of the course. The results indicated that, compared to a control group, 10th-grade students who participated in the course improved their foresight and reduced their decisional difficulties.Of the four methods for instructional career counseling described by Healy (1982, p. 305), counselors may be least familiar with the "teach-the-test" method. Crites (1974) proposed this method of didactic career counseling when he suggested that counselors systematically teach clients the correct answers to items that appear in career development inventories. Crites reasoned that these items assess critical attitudes toward and competencies for career choice. Therefore, counselors might discuss with their clients those items that clients answer incorrectly. At a minimum, this discussion can help clients develop their career-choice attitudes and competencies by having them learn and understand the correct answers to items that they missed. Toward this end, Crites wrote programmatic discussion materials for his Career Maturity Inventory (CMI; Crites, 1973).
