Abstract
This study used hierarchical linear modeling (HLM) approach to investigate the impact of school leadership, professional development, gender and teaching experience on professional commitment with a sample of 396 elementary and secondary school teachers and administrators from Kenya. The HLM results indicate significant differences among schools (?2 (49) = 218.92, p<0.001), with an intra-class correlation of 0.3183 indicating that 31.83% of variance in professional commitment was among schools. When professional development and school leadership were used as level 2 predictor variables with no level 1 predictors, the school variability dropped from 4.73584 to 3.30865 indicating that 30.14% of variance in school professional commitment was due to school leadership and professional development (?2 (47) = 161.67, p<0.001). Further, the reliability of the sample means in any school for the true mean school professional commitment was 0.703.
