This study began by dissecting what the research says regarding students with disabilities, inclusion and its current practices, the characteristics of those leaders that promote inclusive cultures, perceptions of inclusion of teachers and principals, and school culture. The purpose of this dissertation was to explore the perceptions of inclusive cultures of those who practice inclusion in school environments. A focus was placed on the leadership characteristics of principals in schools that implement inclusive practices and how those characteristics influence a positive school culture. For this study, inclusive practices included all strategies and models used to benefit students with disabilities being taught in the general education classroom setting. This Ethnographic Case Study was conducted in a Junior High School in a school district located in southeast Louisiana. The data collection methods included a focus group and individual, semi-structured interviews. The participants included the lead administrator, two assistant principals, one general education teacher and one special education teacher. The interview responses were analyzed line by line to ensure that all responses were included. The researcher placed brackets or parentheses around related phrases. Each related phrase was assigned a code. To create themes/categories, the constant comparative method was utilized. The constant comparative method of analysis allowed the researcher to compare the responses to the questions between each of the informants. The results revealed that the perceptions of leadership characteristics, perceptions of inclusion and inclusive practices, along with the on-campus clubs, programs, and activities, all help influence the positive, inclusive culture of the school, Culture Is the Key Academy (CITKA). The findings in this study suggest several possibilities that could impact policy and practice and expand our knowledge on the topic of Inclusive Cultures.
