Four cases of school integration illustrate that eliminating racial isolation has been shown to have no detrimental effect on majority children. Minority children can be benefited by increasing their achievement levels and IQ scores. All groups can benefit attitudinally. These gains, however, occur only some of the time and only under favorable circumstances. They depend on how the problems of integration are handled by the school district. In Sacramento, California, the schools made a commitment, had a plan, and evaluated what was actually occurring every year, revising and improving their plan as they went along. They called upon and received community support. Both they and the Berkeley schools utilized bus transportation. In Pasadena, the Unified School District sent out mailings to help the parents of their school-aged children become aware of just what desegregation, accomplished via bus transportation, in Pasadena schools would mean to them and what changes it would mean in their lives. The Shaker Heights schools provide another case of effective integration planning. Shaker Heights is a wealthy suburb adjacent to the east side of Cleveland. Between 1955 and 1963 another section of Shaker Heights known as Moreland began to receive a large number of black families. It was evident that something would have to be done to change the racial mix at Moreland and at almost all the white schools. A two year study was made to accomplish this, the results being presented at a large public meeting attended by almost 900 people. (Author/JM)
