Principals' attitudes toward inclusion have been shown to have a positive impact on successful inclusive practices within schools. Providing guidance, support, and training to assist the faculty and staff with inclusion had been acknowledged to make a difference for schools administrators who were making changes to include more students with disabilities in the general education classroom. This quantitative study investigated the attitude of Louisiana high school principals toward the inclusion of students with disabilities in the regular education classroom and measured the extent of the relationship between their attitudes and their demographic profiles using a comparative descriptive design. Findings revealed mostly positive attitudes toward inclusion among respondents who were all high school principals in Louisiana. However, negative attitudes were likely regarding some areas. First, respondents were likely to have negative attitudes toward the training of teachers, paraprofessionals, and principals to cope with students with special needs. Also, negative attitudes were indicated among most respondents toward including students with significant disabilities or students who are continually aggressive toward school staff or students in the general in the general education classroom. Furthermore, negative attitudes were likely toward the additional problems created for teachers' classroom management with inclusion. At the same time, significantly statistic results were revealed among the attitudes of high school principals in relationship to of gender, former special teaching education experience, number of in-service hours in special education, and socioeconomic status as determined by the number of students with free and reduced-price lunch.
