This paper reports a model of the impact of teacher behavior on student achievement. Estimates of the model's efficiency are obtained and its utility tested on a second set of data. Methodological and theoretical frameworks are from sociologists interested in contextual affects phenomena. Data were collected from 374 students during 1971-73. Using standard regression procedures, a model was constructed of the relationship between teacher behavior and student outcomes for 1971-72. The model was verified on 1972-73 data. The findings are ambiguous. The first year model is satisfactory as a post hoc predictor. It is less satisfactory applied to the second year data. The methodology, however, is an advance for the study of the consequences of administrative behavior on the part of teachers. (Author)
