A number of research studies have indicated that issues with school climate may be a source of the low academic and social success of students in the public school system. A poor school climate is often associated with low-performing schools; a positive school climate can increase student achievement and other indicators of school success such as graduation rates. The purpose of this quantitative study was to explore the correlation between teachers' perceptions of their school climate and the empirical data obtained from national studies that initially evaluated the Comprehensive Assessment of School Climate (CASE) survey. The study surveyed 97 teachers to evaluate the school climate of a southern rural high school using the National Association of Secondary School Principals (NASSP) CASE survey. The 55-question survey measured each of 10 climate subscales: (a) student-teacher relationships, (b) security and maintenance, (c) administration, (d) student academic orientation, (e) student behavioral values, (f) guidance, (g) student-peer relationships, (h) parent and community-school relationships, (i) instructional management and (j) student activities. The results were analyzed using single-sample t tests and compared to the data derived from national pilot studies and field tests that used the CASE survey. Data indicated that the school climate of the study school was significantly lower than CASE survey norms on the overall school climate and on all subscales. Recommendations include continued research on school climate issues and ways school climate can be elevated. Implications for positive social change include enhanced student-teacher relationships, improved student achievement levels, and, ultimately, higher graduation rates.
