In this study, the authors compared teacher candidates who followed three pathways leading to certification in adolescence education while attending the same university. A limited number of factors were held constant among pathways, and only factors inherent to the routes were varied. The dependent variables were (1) teacher effectiveness, as measured through Danielson's Observation Scale, and (2) teacher efficacy, as measured through Gibson and Dembo's Teacher Efficacy Scale. No significant differences in efficacy or effectiveness were found.
