While this study has revealed some important district-level practices that support student achievement, some of the findings point to a need for further investigation.

In-depth district case studies might be helpful to gain better understanding of district resource allocations among campuses. Several focus districts report that they are in the process of implementing large-scale changes that they hope will positively impact their performance. It would be very useful to study these districts during the implementation phase to determine the impact of the changes.

An investigation of links between resources such as instructional materials and student academic performance at the campus level could yield important information about resource equity and approaches that improve student learning.
