This report describes the first phase of a longitudinal study of the Sixth Cycle Teacher Corps program, focusing on the relationship between intern background characteristics, Teacher Corps Program characteristics, and intern exit characteristics. Data about all Sixth Cycle projects that prepared elementary school teachers were collected at each site by interview and questionnaire. Data about the exit characteristics of interns were gathered using: (a) classroom observation, (b) log of professional activities completed by interns over a week's time, (c) interviews, and (d) questionnaires completed by interns and their team leaders. Descriptive and analytic results are reported. Analytic findings are: (a) the relationship of intern exit skills was not very strong; (b) Teacher Corps Program characteristics rather than intern background characteristics were most closely associated with intern exit skills; (c) the extent that teacher competencies were specified and used by the project was not closely related to any intern exit skill; and (d) the sets of program characteristics that were most closely associated with intern exit skills were those pertaining to collaborative decision-making, personalization of the program for interns, and the community component.
