This brief focuses on strategies and approaches used in the United States and internationally to re-prioritize the use of time in schools, and explores several areas of time-use beyond those most often cited in the literature. To date, most of the discussion about time has been about finding time for teachers to plan their work and attend professional development programs. In the next section the authors provide an overview of traditional efforts to provide planning and professional development time, the challenges encountered and some innovative efforts to address those challenges. While well-intentioned, these efforts are inadequate to the real need for change in how time is spent in schools. (Contains 35 notes.)
