Understanding effective school leadership as a function of culture building through quantitative and qualitative analyses is the purpose of this paper. The two-part quantitative phase of the research focused on statistical measures of culture and leadership behavior directed toward culture building in the school. The first quantitative part involved the administration of a Leadership Assessment questionnaire to all administrators in a growing school district. The second part involved the administration of a School Culture Assessment questionnaire and a Frames of Reference questionnaire to a random sample of 5 teachers in each of the 12 schools and to 20 central office professional personnel. Quantitative findings indicate that leadership and culture are significantly interrelated. Overall, visionary leadership behavior relates most strongly to teamwork, and effective leadership characteristics are consistent with visionary leadership theory. The qualitative phase of the study involved the application of Deal and Peterson's (1990) five themes of effective culture building to indepth case analyses of five exceptional principals. Qualitative findings indicate that all five strategies are major tools of effective school leaders in the culture building process. The overall finding of the study demonstrates the complementary relationship between quantitative and qualitative methodologies. A table of the Pearson Correlation Matrix data and an extensive bibliography are included. (34 references) (LMI)
