Each physics teacher was given a subjective rating by a traveling physics supervisor after the teacher had been visited at least three times. After the teacher had been visited five times the physics supervisor rated the teacher objectively on a rating blank containing twelve items on a five point scale. Finally each teacher was rated on the basis of the achievement of his students as compared to the average achievement of all students in the program of equal ability after corrections had been made for aid received by those students in the research group.
