A teacher peer evaluation program that was implemented in Dade County, Florida, schools is described in this paper, with attention given to the extent of staff acceptance. Implemented under the school system's school-based management pilot program in 1987, the program trained experienced teachers to observe their peers' teaching behaviors using the district's official evaluation instrument. To measure the extent of teacher acceptance, this study examined three factors: staff attitudes toward the program; teacher rapport; and student achievement. Data were derived from analysis of records of participation and interviews with lead teachers and principals. Outcomes included a general improvement in staff attitudes and rapport; however, impact of student achievement was mixed. Teachers continue to conduct formal observations in schools that implemented the program 5 years ago, but the program has foundered in two schools with collegial coaching. Two figures are included.
