A study was done to (1) identify the practices and attitudes of major Colorado public and private employers toward career development of sub-professional employees, and (2) prepare a self-assessment questionnaire by which employers can compare their practices to those employers of comparable size and type of business. A Likert-style questionnaire was mailed to 244 Colorado employers who employ at least 250 employees. These employers were grouped as (1) mining, manufacturing, and construction, (2) commercial services, (3) wholesale or retail trade, and (4) public institutions and agencies. An analysis of the 138 responses for each of the questionnaire items resulted in several findings in each employer group. One finding for each of the above groups respectively follow: (1) training opportunities are publicized through use of the bulletin board, (2) supervisor recommendations are often used to determine participation in training, (3) participation in training is seldom determined by seniority, and (4) career counseling is often utilized in the planning of training activities. The questionnaire items found to be significant were incorporated into a self-assessment questionnaire for each of the four employer groups. (The appendix comprises approximately one-half of this report and includes a list of employers, the survey questionnaire, tables reporting the item analysis for each of the seventy-two questionnaire items, and a self-assessment questionnaire for each of the four employer groups.)
