This paper explores the characteristics of teachers and their roles at Celebration School, an elementary/secondary school in which the high profile, innovative curriculum, team structure, guiding principles of learner-centered instruction, and high expectations for students create a demanding environment for teachers. Data were collected through semistructured interviews with 10 teachers, 2 administrators, 4 parents, and 6 students. Themes related to the roles and demands of Celebration teachers were identified. Working in teams was the first theme identified. All teachers and administrators discussed the importance of the dynamics of teaching teams. A second major theme was that of the rewards and frustrations of the school's approach and the learner-centered environment. The relationships of teachers and parents was a third theme consistently identified. Celebration School faces many challenges in initiating and maintaining its reforms, especially in the number of simultaneous innovations, the team and open space structure, and the high profile these efforts have generated. Faculty members are sometimes frustrated by the demands placed on them, and it is essential that Celebration find ways to support the teachers and to communicate the school's mission to parents. (SLD)
