This study examined the perceptions of teachers and students during the first year of implementation of the International Baccalaureate (IB) Diploma Program at a high school. The research team interviewed all IB teachers and students regarding their decision to teach/enroll in IB; how IB differed from teaching/taking regular courses; and other facets related to the Program. IB faculty and students perceived the Program positively, believing it challenged them to be better teachers and higher achieving students. The study also cited the increased workload of teaching/taking IB courses and its impact. Policy recommendations are offered for schools utilizing the IB for the first time, and guidance is provided to parents regarding the suitability of IB as an option for gifted students.
