Effectiveness of on-the-job training (OJT) in maintenance has become more important in recent years due to increased technological sophistication of military equipment and systems, the diversity of tasks which a service person may be asked to perform, and the need for persons to have skills necessary to move within their speciality area. There are deficiencies in current OJT including problems caused by the work situation and environment and the way the trainee is managed within it. In addition, problems arise when there is failure to enhance the work experience with proper resources, most importantly trainers. There is a lack of qualified OJT trainers and, even when available, good trainers may be poor instructors. A general solution is to formalize the task training portion of OJT in each operating unit. All apprentices should master certain skills identified by informed and concerned supervisors. The quality of instructors must be upgraded and task training must be done realistically (using actual equipment, experiencing malfunctions and unscheduled maintenance). Training should be given when the need arises. Management of training must insure relevance to the job. Successful training programs include the Air Force Task Oriented Training and Maintenance Training Management. (FP)
