This study investigated the hypothesis that industrial training directors are required to perform educational duties for which they lack appropriate, organized instruction. Questionnaires were sent to 778 principal training directors, of whom 238 responded. Data were obtained on sizes of firms represented, numbers of trainees served, employment standards for training directors, job titles of training directors and their immediate superiors, employment experience and training and development background, subordinate staff, major duties, educational background, self-perceived educational needs, and the educational and work background (including general and specific courses in education, business, communication, and psychology) which the respondents considered desirable for their successors. Only a third had master's degrees in business or education. Assessing present and proposed training activities and coordinating company training were named as the most important duties. Respondents tended to believe that certain duties could be learned only on the job; however, the greater the number of trainees, the more likely a respondent was to prefer that his successor have an advanced degree in business and/or education.
