The main objective of the following paper is to identify, by a revision from the specialized area literature, the needed knowledge required by teachers to promote the inclusion of students with special educational needs (SEN) in regular education. To achieve this goal, was prepared a bibliographic survey from seven magazines, ten books’ chapters and three dissertations from Education and special education area, produced between 2005 and 2009. The achieved data was organized into categories. The results indicate the necessity of specific theoretical, conceptual and methodological knowledge to include students in an ordinary classroom. Between all knowledge indicated by the checked authors, is pointed out the understanding related to corporative and collaborative method and technique to favor the inclusion of students with SEN; the characteristics of these students, to the procedure didactic-pedagogic to favor the inclusion; to the legislation and fundamentals from inclusive education; to the social barriers that difficult the inclusion process from students with SEN, among others. We consider that this research result can contribute to subsidize the content organization which will be contemplated in the teaching training and continued formation process and/or teachers who are working to favor the inclusion process for SEN students.
