Dornbusch argues that there is not enough control over the school system, and the system of evaluating schools should be reconsidered. He proposes that schools be evaluated by the teachers working there because they know the job firsthand and would be able to communicate more clearly what criteria to examine in an evaluation. Surveys indicate that most teachers are ignorant of what is expected of them and feel they are not evaluated enough. Dornbusch also addresses the effect of the current evaluation system on students. According to his findings, African-American and Spanish-surname students were doing relatively poorly overall, but they perceived that their teachers were friendly and that they were putting enough effort into their studies. He concludes that the academic standards and evaluation system affected the students' assessment of their own effort and achievement, so that the minority students were hurt by a distorted evaluation system.
