In recent years changes in the constituency of higher education have been characterized by a substantial increase in the number of students attending college less than full-time. As a consequence the once sharp distinctions between youth and adult students, campus and extension education, and traditional and nontraditional clients are giving way to recognition of greater heterogeneity in student populations. The growth in the number of part-time students has been advantageous in a time of declining full-time enrollments. At the same time, the trend has caused concern and some changes in several areas of higher education, including institutional finance, student recruitment, academic programs, teaching, support services, and student participation in campus activities. As a result, policies for this new majority in higher education will be shaped in the forseeable future by very different and more changeable social and educational priorities, requiring much more flexibility in higher education, even from year to year.
