This study examined the relationship between school climate and student achievement ratings in urban school districts in five states (N = 230). Many educators view school climate and student achievement as separate considerations. However the results of this study suggest that climate and student achievement were highly related. In fact, the quality of the climate appears to be the single most predictive factor in any school's capacity to promote student achievement. The findings of the study suggest a series of general and theoretical implication for the field of education. It appears that the use of practices that promote a "psychology of success" lead to greater achievement and higher quality climate, and those that promote a "psychology of failure" lead to underperformance.
