This longitudinal trend study (Gall, Borg & Gall, 1996) examined the effectiveness of a one-semester university-based teacher induction program as compared to a two-semester university-based teacher induction program based on the observation scores of classroom teaching behaviors urban novice teachers exhibited during the first year of teaching. These scores were further analyzed in relation to the socio-economic level of the school and the grade level taught. Additionally, the study explored the past participants’ perceptions of the teacher induction program components of a one-semester program and a two-semester program during their fifth year of teaching. Their perceptions were also examined in relation to the socio-economic level of the school and the grade level taught. The study examined the observation scores of classroom teaching behaviors of 145 urban novice teachers participating in either a one-semester or two-semester universitybased teacher induction program. The urban novice teachers demonstrated growth over time as measured by the first and final observation scores of classroom teaching behaviors. However, the length of the university-based teacher induction program did not affect the observation scores of classroom teaching behaviors. Further, neither the socio-economic level of the school nor the grade level taught affected the observation scores of classroom teaching behaviors. Although the three components of the university-based teacher induction program received high means, 82 past participants of a one-semester or a two-semester teacher induction program responding to the Teacher Induction Program Participant Survey (TIPPS) recognized formative observation as the most effective component. Peer support and professional development were perceived second and third respectively. No statistical significant differences of the one-semester or two-semester past participants’ perceptions of peer support, professional development or formative observation were found related to the socio-economic level of the school or the grade level taught.
