This study compares research on the theoretical models and predictors of teacher effectiveness with those of other occupations. Four models of teaching are identified—labor, profession, craft, and art—each with its own (often implicit) objectives and theories about how learning takes place. In addition, there is considerable similarity between the teacher characteristics that predict teacher effectiveness and those predicting worker effectiveness in similarly complex occupations and professions. Specifically, cognitive ability and experience predict effectiveness for both groups, whereas personality and education are not predictive. These specific findings are informative for developing specific models of effectiveness.
