In first part there are general questions about age, level of education, experience working in school. Second part includes 47 items divided in 7 areas, experience with SEN students, attitudes about disabilities, knowledge, acceptance, professional support in school. Results shows that about 70% of examined teacher have none or very little knowledge about teaching SEN students, and their attitudes are mostly negative but younger teachers experience higher competencies. Further, some teachers that have positive attitudes about inclusive education would not accept SEN student if could make choice. Competencies of examined teacher in regular school are not equally developed. Reason for those findings, in some aspect, could be found in teacher training college program which has been changed in last decades. According to results, and teachers personal perception of their own competency, conclusion that teachers do not have necessary skills and competency can be made.
