The article focuses on the report of the Committee on Teacher Development which provides a formidable list of attributes of the "excellent" teacher, but nowhere defines the "superior" teacher. A superior teacher might be someone who possesses a considerable number of the attributes of an excellent teacher, that is, he might be good at the job. Alternatively, by a superior teacher the committee might mean a senior teacher. It is likely that graduate assistants will be expected to attend the classes of senior teachers. The committee rightly points out that judging classroom performance is important and controversial. Student evaluations of teachers are in most cases unreliable and in some cases positively misleading. Particularly where salary raises have a relationship to teaching effectiveness, the knowledge that the teacher is subject to student evaluations might have unfortunate psychological effects on young teachers. Most obviously, teachers might be tempted to orient courses not towards maximum student benefit, but towards maximum student approval, and there is no reason why the two objectives should be coincident.
