This study examined the effectiveness of a fifth-year teacher preparation program that included a year-long internship as preparation for the first full year of full-time teaching. Subjects for the study were nine first-year teachers who had completed the year-long internship as part of their certification program and were subsequently employed as teachers by the school system in which they had served as interns. For comparison purposes, two of three student teachers who completed certification requirements at the same time as the interns, trained at the same university, and were employed in the same schools as the interns were included in the study. The interns will provide insights into the relationship between the internship program and the following year of teaching. Their principals were included in the study to form comparisons between the performance of the interns and that of student teachers whom they had supervised as first-year teachers. Data were collected through interviews and observations. Final analyses that will yield a composite of the study were in the process of being completed. (JD)
