The third booklet in the series Career Development in Head Start is designed to provide the career development coordinator and other Head Start personnel with a better understanding of adult development and how adults learn, thereby enabling them to counsel Head Start career aspirants more effectively. Transcripts of interviews with paraprofessional Head Start staff members from different racial, ethnic, cultural, and regional backgrounds are used as case examples to illustrate some of the elements of adult development and adult learning. Comments dealing with motivation, expectation, perception, and self-actualization are emphasized because they recur frequently. A discussion of developmental tasks and how adults learn and a bibliography are also included. (Author/KM)
