Leadership roles performed by teachers after implementation of a school-based management (SBM) plan in Florida are described in this report. Telephone interviews with principals of each of the 33 participating schools were conducted to identify the leaders of the participating school bodies, or "cadres." Findings indicate that 75 percent of the most active members were classroom teachers. That two-thirds of them were elected indicates voluntary involvement despite an increased workload. However, a comparison with districtwide statistics indicates that administrators are overrepresented in the cadres, underscoring the cooperative nature of the shared decision-making process. (LMI)
