This qualitative study was designed to investigate teachers' perceptions of the impact of inclusion of children with special needs on their classes. Twenty participants were randomly selected from the 25 teachers who had volunteered for the study. These teacher participants completed a survey which was composed of 62 items dealing with attitudes and perceptions, incentives for encouraging inclusion, and concerns from a classroom perspective. From these 20 participants, five teachers were then randomly selected for interviews. Findings revealed that some of the teachers' primary concerns were planning time, meeting the needs of all students, and ongoing professional development to respond effectively to the increasingly diverse needs of students in the classroom.
