Summary: This report presents the findings from a study to describe how Americans in transition study for college credit and to establish the extent of degree versus nondegree study. Introductory materials discuss why and how the study was made and the annual rate of adult credit study. Part I describes the demographic characteristics of the 1,000 adults interviewed who had taken a course or an entire program for college credit at any time in the previous two years. A discussion of each characteristic makes observations and offers interpretations. A graph illustrating the findings follows each discussion. Part II begins with descriptions of the type and nature of degree study among adults and then continues with descriptions of patterns of adult study among both degree and nondegree students combined. The same format as in part I is followed: observations, interpretations, and a bar graph. Part III concludes the report with descriptions of differences among adult students with respect to demographic characteristics and patterns of study. (YLB)
