A study published in the June issue of Educational Administration Quarterly looks at the causal impact of McREL’s Balanced Leadership® (BL) professional development program on principals’ learning, beliefs, and behaviors. Researcher Roger Goddard and his colleagues compared a treatment group of 100 principals in rural Michigan who participated in two years of BL training with a group who did not receive training. Results showed that participating principals reported substantively significant growth on the majority of outcomes targeted by BL, with the largest impacts on sense of efficacy for instructional improvement, reported ability to bring about change, and strength of norms for teachers’ instructional practice. Interestingly, principals were more likely to report growth on broad, school-level outcomes than in areas that involve them working directly with teachers.
