This research study investigates the perceptions of secondary school Greek teachers towards the "integration" policy of pupils with emotional and behavioural difficulties (EBD). Therefore the sample was secondary school teachers from the district of Ioannina (N=350) who completed a questionnaire of five self-reports scales.The purpose was to measure the perceptions of secondary school teachers in connection with the possible equal opportunities recognized in such teenagers with regard to their access to knowledge (Equal Opportunities Scale), their opinions about the causes of relative psychomental problems (Causes of EBD Scale) on the same teenagers, their thoughts about the best possible approaches that those children could enjoy (Coping Strategies Scale), as well as their opinions about the best strategies adopted on the same direction (Effective Approaches Scale).
