|Abstract||Analyzing the effects of the Equine Essentials discipline model by examining measurable differences in teacher holonomy at schools applying the model with varying degrees of intensity was the purpose of this study. The study decomposed the analysis into tests for the presence of each of the five dimensions of holonomy: efficacy, craftsmanship, creativity, flexibility, and interdependence. Greater individual holonomy, or the extent to which people recognize and manage the tension between themselves as individuals (i.e., as a teacher) and themselves as part of a larger functioning whole (i.e., a school), is desirable in that it facilitates excellence among teachers and schools. The study followed a quantitativequalitative triangulation approach through the use of surveys, interviews, and an analysis of state test results from participating schools. The survey results failed to reveal any correlation between the discipline model and the five components of teacher holonomy, however, teacher interviews and the analysis of state tests were suggestive of a positive correlation between the discipline model and improved teacher efficacy and flexibility, with some support for a link between the model and craftsmanship.
