The schedule is important as a reflection and “interpreter” of your mission.1 It determines what is deemed important, decides who is important, reflects the power structures of the school, forces actions by students and adults whether desired or not, influences issues of discipline, can mitigate or exacerbate stress, and enhances or detracts from academic performance. Its importance has been underestimated, and thus its change power not clearly understood. That power relates to the school’s mission, to the school’s strategic direction, to the school’s 21st century character, and to its influence on student and faculty culture.
