Catholic school principals typically serve as the prime decision-makers in admission and enrollment issues. A key factor in this decision-making can be the principals' perceptions and attitudes about servicing students with disabilities within a Catholic school context. The purpose of the present study is to investigate the attitudes and perceptions of Catholic school principals toward inclusion of students with disabilities in Catholic schools. Overall, a majority of surveyed principals reported a positive attitude toward including students with disabilities. Some significant relationships were found between principal's pervious experiences with students with disabilities and the principals' willingness to enroll students with disabilities. Implications for practice are presented.
