This book examines how teacher incentive pay and career ladder programs have been implemented--what forms they've taken; what issues arose as programs were established; what their impact has been so far; and what their future might be. It provides a program taxonomy and conceptual framework for understanding current trends within this still-evolving reform movement, including resistance to the change process. Most important, the book analyzes the potential impact on the real world of schools and how these programs affect teachers' skills and students' learning.
