The Park City School District (Utah) career ladder design provides a system in which teachers are positioned and paid according to successful performance and differentiation of responsibilities. It includes an evaluation system to differentiate among teachers. The career ladder design presents a number of innovations; for example, excellent teaching is recognized in a variety of forms. It improves existing tools, e.g. student reports. The design uses lines of evidence which other systems neglect, such as pupil gain and parent input. It addresses the problems of madatory evidence systems, such as whether or not to require all teachers to take standardized tests, by emphasizing teacher decision making. This report begins with a description of the career ladder structure. It then describes teacher evaluation and decision making systems. It concludes with a description of evaluation procedures. The appendices include issues about the lines of evidence, evaluation forms, critiques of the system by outside audiences, and a bibliography of resources used in the design. (JD)
