Middle school improvement and reform: Development and validation of a school-level assessment of climate, cultural pluralism, and school safety.

The structure of perceived school climate and the relationship of climate dimensions to adaptation were examined in a large-scale multi-year investigation of students who attend middle-grade-level schools. Analyses of the structure, reliability, interrater convergence, and stability of school climate ratings were conducted in a large-scale sample of over 105,000 students in 188 schools. The climate scales exhibited a stable dimensional structure, high levels of internal consistency, and moderate levels of stability over 1and 2-year time intervals. The relationship between climate ratings and studentsʹ adjustment was examined in 3 increasingly large samples of schools and students that were collected during successive years of this project. Ratings of multiple climate dimensions were associated consistently with indexes of academic, behavioral, and socioemotional adjustment.
