Teachers' beliefs in inclusive education can be highly significant in the success of inclusive classrooms resulting in the performance outcomes of students. Teachers' understandings and expectations of students are important if students are to reach their potential. This study investigated 182 Australian secondary teachers' beliefs about inclusive education in relation to their causal attributions toward students with specific learning disabilities. This study was a quantitative study that used a survey instrument to measure teachers' attributional responses to students with and without specific learning disabilities. The findings show that teachers who believe in inclusive education report to be more positive/encouraging in their feedback towards students, feel greater sympathy toward them, as well as hold higher expectations toward the future than their counterparts. Teachers need to believe in inclusive education if students are to reach their potential at school.
