In the last 20 years, increasing numbers of students with educational challenges (SECs) have been included in mainstream schools. Inclusion creates complex classroom situations for mainstream teachers who need to have excellent decision‐making skills and the ability to face and resolve ethical dilemmas. College students and pre and in‐service teachers were asked about their attitudes towards SEC inclusion, as well as three open‐ended dilemmas during vignettes depicting challenging situations in inclusive class forcing decision‐making. An online closed and open‐ended questionnaire was administered (n = 489). The analysis revealed significant differences in the type of solution to these dilemmas in the three groups. There was a significant interaction between high sensitivity to the feelings of the inclusive students and the participants' overall tendency to support the inclusion of the SECs, positive attitudes towards inclusion, low expression of stigma and a higher sense of self‐efficacy. Implications and practical offers are discussed.
