This report analyzes turnover among members on core planning teams (CPTs) in the 41 Phase I Chicago (Illinois) public schools participating in the Project CANAL model for school-based management. The analysis covers two periods of time: Year 1 to the beginning of Year 3, and Year 2 to the beginning of Year 3. Overall, substantial turnover was noted for both time periods. For the first period, the following percentages of new members were found: (1) 29.3 percent of the principals; (2) 53.4 percent of teachers; (3) 54.9 percent of the ancillary staff; (4) 73.9 percent of the parents; (5) 84.7 percent of the community members; (6) 61.2 percent of all CPT members; and (7) more than 6 out of 10 members were new over a 2-year period. For the second period, the following percentages of new members were found: (1) 22 percent of the principals; (2) 34.6 percent of the teachers; (3) 26.6 percent of the ancillary staff; (4) 40.3 percent of the parents; (5) 55.7 percent of the community members; (6) 34.1 percent of the Professional Personnel Advisory Council members; and (7) almost 4 of 10 members were new over a 1-year period. The paper also includes a discussion of the importance of stability to implementation of the school-based management model. Included are two tables. Appendices present the following: (1) a list of the 41 Phase I CANAL schools; (2) a list of training center activities; (3) an outline of the monitoring commission staff; and (4) data concerning budget status.
