The purpose of the study was to evaluate Florida Association of Christian Colleges and Schools (FACCS) high school student perceptions of the relationship between ideal and real classroom environments. The quantitative, non-experimental research design with a survey was used to understand students' overall perceptions of attending five Christian schools and how they perceived the classroom environments. Student perceptions of their classroom environment are a topic of essential importance to the Christian school. The data provided vital insight using nine dimensions measured using a standardized tool, the Classroom Environment Scale (CES), developed by Edison Trickett and Rudolf Moos. Dimensions in the tool included relationship, task orientation, student competition, teacher order and organization, classroom rule clarity, teacher classroom management, innovation, teacher support, and teacher involvement. The data presented significance between the student perceptions of the ideal and real classroom environments regarding teacher support and teacher involvement in FACCS schools. The study contributes important information for administrators and teachers of FACCS Christian schools to improve teacher support and involvement and continue providing excellence in the other dimensions where students felt satisfaction.
