A study examined the career and professional development activities of postsecondary and adult vocational teachers without degrees in education during their first five years in vocational education. Data were gathered five years after course completion from people who enrolled in a course required for licensure as vocational teachers. The primary reason people took the course was to obtain initial vocational licensure. The two most important factors that attracted people to become vocational educators were their desire to share what they know and to work with students. Postsecondary and adult groups differed significantly on a number of the factors that attracted them to vocational education. The majority had prior teaching experience, participated in professional development activities, and felt there were employment advantages to having a degree in vocational education. Significant differences were found between the adult and postsecondary groups in the numbers of courses taken in instructional methodology and vocational education and in the amount of related work experience. Five years after entering vocational education, only 51.8 percent of the group was still in vocational education. The most important reasons for leaving were career advancement and job elimination.
