Two challenges that confront principals attempting to generate effective collaborative planning time with teachers are examined in this document: altering the conventional schedule and ensuring productive use of planning time. Principals, superintendents, and other educators were interviewed about the techniques and outcomes of these two aspects. Strategies used by respondents for finding the time included grants and staff development, creative scheduling, and substitute teaching by administrators and colleagues. Restructuring the weekly schedule is complicated, but the logistical problems can be solved in a variety of ways. Facilitating productive planning time is more elusive, but can be achieved by defining a mission, articulating goals, grouping teachers, providing staff training for collaborative skills, and using agendas and reports. The examples demonstrate that it is possible to provide weekly planning time and to make that time productive. (7 references) (LMI)
