The Power of Focus: More Lessons Learned in District and School Improvement, 2nd Edition, details a framework and strategies to help schools and districts make data-driven decisions to improve the learning for all students regardless of race, gender or socio-economics. An examination of the Seven Areas of Focus shares concrete strategies for implementing the framework, suggestions for district support, and hands-on tools for leaders to launch the work in their own schools and districts. A thorough discussion of leadership and district wide improvement suggests that student learning demands improvement at all levels of the system, and provides examples for using student and district data to make improvements based on identified needs. The authors are principals at Focus on Results, an international consulting group comprised of successful practitioners, all of whom have been in leadership positions in schools and districts that have shown dramatic improvement in student learning.
