In order to develop a scale to measure student attitudes toward desegregation in their own schools, 61 Likert type statements were developed and administered to over 3000 black and white middle school students in five schools in a southwestern community. Gordon Allport's criteria, particularly his contact theory of desegregation, provided the theoretical base for the study. Factor analysis of the responses yielded five factors which served as the basis for grouping 50 items into a five subscale test. The five emergent factors concerned (1) the concept of interdependence of groups; (2) perceptions of supportive organizational norms; (3) intergroup associations and interactions; (4) the criterion of equal status; and (5) students' acceptance of others different from them as peers. The internal consistency reliability of the scale was .92. Of seven other measures taken to test the validity of the scale, five were correlated highly with the total score and the subscale scores.
