Student affairs professionals have come to realize that the student body on college campuses is changing. Adult students are filling the spaces left vacant by a diminishing traditional-aged student population. Interventions in student affairs, however, are often targeted for the specific developmental tasks of the traditional student. Student affairs professionals need to give greater consideration to the developmental needs of adult learners. Adult learners have a common need for interventions which focus on the transition process. To provide services to adult students, student affairs professionals need a knowledge base of current literature on adult transitions. In addition, a distinction should be made between a developmental model and a medical model as the foundation for establishing intervention goals for the adult learner who is in transition. New systems of service delivery are required to meet the needs of the growing college population of older students. Service delivery areas important in meeting the needs of older students include specialized services, advocacy, referral, networking and mentoring, education, provision of a clearinghouse linking students to campus services, program planning, and counseling.
