ABSTRACT
This chapter begins with assessment or evaluation can have several purposes, only one of which may be to demonstrate accountability. Teachers – and schools – may be assessed in the name of accountability. A school has as one of its prime objectives the development of language skills, a global aim. The national study into excellence in USA schools published in 1983 under the title A Nation at Risk took a sophisticated approach. If the evaluation is carried out for school improvement, and especially if the exercise concentrates on the school's prime task, then the performance of the teachers may be a crucial part of the assessment. The application of economic models and rational indicators to the performance of educational organisations and to teacher activity runs into one of the most problematical aspects of education. The Dror model provides a systematic framework within which to develop the several elements of assessment.
