A study identified related skills needed in five diploma programs offered in the Technical Division of John C. Calhoun State Community College in Decatur, Alabama. The programs were automotive technology, refrigeration/air conditioning, electrical technology, design drafting technology, and cosmetology. Thirty-five area businesses and industries that hired employees in the five selected occupational areas were surveyed to determine which skills in mathematics and communications were needed in each of the occupations and to determine if there was a core of skills needed by all five occupations. The survey was conducted in small group meetings; follow-up visits were made to some businesses to review training materials and programs. All listening, oral communication, and reading skills listed on the survey were considered necessary or highly desirable for all occupations. No clear pattern of responses to written communication skills emerged. Mathematics competencies needed for all occupations were basic computational skills, measurement and conversion skills, and problem-solving skills related to ratio and proportions and the use of formulas. Most communication skills surveyed were generic and had application across all occupational areas. However, certain math skills varied in their application to different occupations. A review of research on related skills was conducted as part of the study. Recommendations for curriculum improvement were made. (The survey instrument and 25 references are included.) (YLB)
