A study was conducted to determine whether a significant relationship exists between the teacher's judgment of her pupils' social status and the pupils'"actual social rank" in the class. Six teachers (one for each grade from one through six) in a selected northern Indiana elementary school were given forms listing their pupils' names accompanied by three columns designated "work companion,""play companion," and "seat companion." On these forms, teachers ranked their pupils according to how they perceived each pupil's acceptance by his classmates in each of the areas. Then three different sociometric tests were administered to the pupils so they could rank each other in each of the three areas. The Spearman Rank-Order Correlation Coefficient was used to determine the relationship between the teachers' judgments of pupils' sociometric status and the actual sociometric status as measured by the sociometric tests. It was concluded "that there is a difference between teachers in the accuracy of their judgments concerning the sociometric status of their pupils." Therefore, it is recommended that further research be conducted in this area in order to determine how teachers' judgments may be improved so that teachers can, in turn, become more effective in promoting the social adjustment of pupils.
