摘要:Abstract The present study has as its basis the commitment and interest with the quality improvement to the diversity awareness through improvement plans. The main goal was to determine the main components of analysis of the quality of the centers that serve the diversity, from the teacherś perspective. The purpose is to appreciate the teacher staff perception about the plans for the improvement of attention to diversity. This is a descriptive and evaluative study in which we have designed and validated a questionnaire that was applied to 112 E.S.O. teachers. The results showed that there is a majority agreement on the revised researches on the deficiency in the resources that schools have to deal with the diversity. The number of students that make up the classrooms of E.S.O., its diversity of personal situations, lack of funding and support staff makes a low involvement of teachers in the design and development of improvement plans. We conclude that teachers consider necessary for the improvement of the quality of diversity awareness some aspects as an adequate number of students per classroom making their education more personalized; a close relationship between schools and families; adequate material resources to the different diversities, and collaboration between the different professionals at the school.
