This study detected and explored the existence of two proposed school cultures, the use of leader actions by principals, and the relationships between them, of a sample of 42 public schools in Southeast Florida. A quantitative non-experimental design was used, guided by eight research questions. One instrument, the BSJQ, was created for the purposes of detecting school normative cultures and another, the SLQ, was refined and used to detect principal leader actions. The existence of Business and Social Justice cultures was confirmed, and three latent cultures of Standards Performance, Democratic Community and Equity Curriculum were discovered. Of the schools participating, 74% had at least one of these cultures. The use of four leader actions was measured and statistically associated with different detected cultures. Managing/Transforming and Bridging actions were associated with all, Bonding was associated with all except the Equity Curriculum culture, and Bartering was associated only with the Business/Standards Performance culture. The schools' context had limited impact on the relationship between actions and culture.
