Prisoners of Time (NECTL, 1994) reports that students and teachers are victims of inflexible and counterproductive school schedules.
The categories in the survey directly correspond to the most often cited obstacles in promoting effective professional development of time, scheduling, and continuing education requirements (Darling-Hammond, 2000; NCTAF, 1996; NECTL, 1994).
This corroborates with research that time and scheduling are major issues in professional development (NECTL, 1994).
