Part-time instructors have been increasingly in demand in adult and vocational education. The two greatest benefits an educational program realizes by employing part-time instructors are cost savings and staff flexibility. Part-time employment offers certain benefits to instructors. Particularly drawn to such teaching commitments are semiretired professionals, individuals enrolled in full-time degree programs, and people who wish to augment their income by holding a second job. Lower salaries, lack of health insurance and other benefits, and lack of negotiation power regarding raises and promotions are among the frustrating aspects of part-time employment. Because they are employed primarily for their professional competence rather than their pedagogical training, many part-time instructors lack the teaching skills and teaching experience required in the classroom. Despite the importance of professional development, few institutions offer such activities to their part-time instructors. Four broad categories of training needs are introduction to the educational setting, development of basic skills needed by part-time adult educators, refresher courses for experienced workers, and specialized courses such as counseling, assertiveness, and computers. The instructional quality of part-time faculty can be improved through orientation, education and training, evaluation, and administrative support. (Contains 13 references.) (YLB)
