This paper presents results from research and evaluation of the "Pilot Arizona Career Ladder Teacher Development and Incentive Program." The project, initiated by the State legislature, allows each local education agency to design its own plan. By 1989, the project will provide evidence for the legislature to make informed decisions about the success of the 16 district pilot tests of their teacher development models. The business community, three universities, professional organizations, the governor's office, both houses of the legislature, and 16 school districts, with more than 10,000 educators, are involved in this experiment, based upon scientific research on career ladder programs and problems. The legislature mandated a 5-year research time that is implemented by and grounded in the political support of educational and business representatives. The emerging model has some specific directions and accomplishments that have not been apparent in other plans being implemented. This report is organized under four major headings: (1) "The Historical Antecedents"; (2) "Reasons for Program Failures"; (3) "The Possible Program Solutions"; and (4) "The Pervasive Concept of Change."
