The monograph presented by its research results points to the preparedness of educators to educate children and pupils from the environment of social exclusion, which can be assessed as significantly insufficient. The topic was part of a nationwide research plan and was diversified into three areas. The focus was on the orientation of teachers in relevant issues affecting the school education process. We were interested in the real field practice of teachers, especially their approach to the application of support measures. Their view of inclusive education was an integral part of monitoring. Reserves have been identified in all areas that negatively determine their own preparedness. A total of 2005 respondents from 13 regions of the Czech Republic working in all types of primary schools were involved in quantitative-oriented research. The research findings underline the importance and current need for a new effective concept for the system of continuing education for teachers and the introduction of career (qualification) growth for teachers.
