This study was conducted to examine the intellectual inspiration and productive school culture of public secondary school teachers in Tarragona District, Division of Davao Oriental. A non-experimental quantitative research design utilizing the correlational method was employed. The respondents consisted of 133 public secondary school teachers, selected through universal sampling to ensure that the entire population was included. Data were analyzed using mean, Pearson correlation coefficient (r), and regression analysis. The findings revealed that both the intellectual inspiration and productive school culture of teachers were generally high. Furthermore, a significant positive relationship was found between intellectual inspiration and productive school culture among public secondary school teachers. The study also showed that the domains of intellectual inspiration significantly influenced the development of productive school culture. These results suggest that school administrators can further enhance both intellectual inspiration and productive school culture by focusing on areas with lower scores, particularly in creating a predictable and stable environment that promotes healthy interactions among teachers.
