Self-help ✦ Penny’s Take
School Leadership that Works
Robert J. Marzano · 2005
74/100
👍 Worth It
A research-backed framework for school principals drawn from a meta-analysis of 69 studies — if you lead a school or are studying educational administration, the specificity here is genuinely valuable. The correlation-not-causation caveat is real and the book doesn't fully account for demographic variation, so it should be read as a strong starting point rather than a final word. For its intended professional audience, it earns its reputation.
