This study investigates how the culminating teacher preparation program (TPP) experience (either student teaching assignment or internship) influences the perceptions teachers report about their ability to perform instructional tasks required of teachers. A multivariate ANOVA test (N = 502) was conducted to compare perceptions of student teachers (those who taught 15 weeks) and interns (those who taught a full academic year) at two points in time--once at the conclusion of their TPP and again after their first year of teaching. Results indicate that overall, student teachers report higher perceptions of their ability to perform instructional tasks than interns do at both the preservice and inservice teacher stages. Interns reported higher scores at the inservice stage on only the mathematics subscale, suggesting that there is some change in self-efficacy as teachers gain teaching experience. Findings suggest that the student teaching context provides more modeling and verbal support and produces teachers with higher perceptions of teaching ability than those who complete an internship.
