This paper presents results regarding the development, research, and evaluation of unique aspects of the Arizona Career Ladder Teacher Incentive Program. The first section presents a brief overview of the historical perspective of career ladders and teacher incentive programs. The second section, which describes the Arizona model, details its unique aspects, including: (1) collaboration among government, business, universities, school districts, and the teaching profession; (2) teacher evaluation systems; (3) totally restructured salary schedules; and (4) a pilot research and evaluation project. The third section presents results of an evaluation of the program, which indicate that the model is already showing significant strengths and weaknesses which will allow a workable model to be developed.
