An investigation into the relationship of organizational climate and academic optimism as predictors of student achievement and school effectiveness was conducted. De-identified secondary data from 67 elementary schools in the Northern portion of Alabama were used. The instrumentation for this study included School Academic Optimism Survey (SAOS), Organizational Climate Index (OCI), the Index of Perceived Organizational Effectiveness (IPOE) which is now known as the SE Index (School Effectiveness Index), a composite score for Academic Achievement (AA), and socioeconomic status (SES). Ordinary Least Squares Block Regression method was used to test the effects of the independent variables separately and together on school effectiveness and academic achievement. The results suggested that all variables had a moderate correlation with each other. Also, when controlling for SES both optimism and climate served as independent predictors for achievement and effectiveness. When entered into a regression model together while controlling for SES, climate predicted achievement while optimism did not. This was likely due to the small sample size as compared to the number of predictors in the model. Both climate and optimism served as predictors for effectiveness when in the regression model. The results of this study lend further support to the importance of School Academic Optimism and Organizational Climate as predictors of academic achievement and organizational effectiveness.
