This study compares the administrative styles of principals of junior high schools with those of middle school principals. It also examines the school climates of these schools and analyzes the relationships between climate and administrative style. The population for the study consisted of 77 teachers from 19 middle schools and 69 teachers from 19 junior high schools, all in the Midwest. The Purdue Rating Scale for Administrators and Executives and the Organizational Climate Description Questionnaire were employed to measure, respectively, administrative style and school climate openness. Multivariate analysis of variance was used to analyze teachers' perceptions. Multiple linear regression analysis was employed in the second phase of the study to analyze the linear relationship between the dependent variable, school climate openness, and the predictor variables. Findings revealed no statistically significant differences between climate, style of administrator, and school organization. A linear relationship was found between the predictor variable "democratic orientation" and the dependent variable "openness." The data clearly indicated that principals exhibiting more emphasis on democratic orientation were administering schools with more open climates. (Author/MLF)
