ABSTRACT
This chapter provides a historical background on how evaluation models have developed, and possibly improved, over the years, with discussion of the resulting models of evaluation that are in use today. The evaluation criteria are a refinement of the roles defined by the national organizations for each position based on the experiences of specialists in schools across the country. As a starting point, a quality specialist evaluation system should reflect the standards developed by the Joint on Standards for Educational Evaluation: propriety, utility, feasibility, and accuracy. The Feasibility Standards state that evaluation systems should be "as easy to implement as possible, efficient in their use of time and resources, adequately funded, and viable from a number of other standpoints. Feasibility Standards state that information must "be technically accurate and that conclusions be linked logically to the data".
