Improving Student Achievement: Reforms that Work expands on the first volume in the Milken Family Foundation series on education policy, ""Talented Teachers: The Essential Force for Improving Student Achievement."" The series explains to policymakers, parents, business leaders, and teachers the importance of teacher quality in increasing student achievement. This volume is based primarily on the proceedings from the 2004 Milken National Education Conference (NEC), which was held in Washington, D.C., in May 2004. Reform of any kind is an arduous process. It requires forward thinking, hard work, collaboration, and commitment on the part of teachers, administrators, policy leaders, and other supporters of the endeavor. Education reform in particular can be especially difficult due to the many ingrained features of our current K-12 system; however, it is vital to learn from our past mistakes and break the cycle of failed efforts in order to fix the system that is the lifeblood of our country's future success. These proceedings provide insights into some of those past efforts as well as some of the current initiatives that provide optimism and hope in schools across the country. From these examples, we recognize that it is imperative that we improve student achievement by embracing reforms that work.
