As I support campuses that are struggling academically, the need for a principal's instructional leadership role is increasingly evident in all aspects of a school improvement. For example, simply ordering intervention materials to supplement a core curriculum is not enough. Rather, spending time reviewing specific uses for supplement
al materials such as test practice, scaffolding resources and spiraled reviews is necessary to streamline the effectiveness of interventions. Teachers should be clear on which resources are earmarked for which part of the day, and which are off limits during parts of the day. In order for outside of class interventions to be successful, they must be extensions of classwork, while carefully not duplicating classwork. Matching resources to specific needs and purposes of interventions is paramount to rapidly increasing student achievement.
