Building upon the previous chapter’s discussion of the importance of a shared vision, this chapter will address the fleshing out of that vision through a cycle of school improvement. It will explain how the school’s vision statement—if current, relevant, and understood by stakeholders—is central to all school-improvement initiatives. This chapter will present theories and practical models for data-driven decision making and will outline recommended steps for setting realistic goals, implementing those goals, and assessing the degree to which they have been met.
