School Leadership That Works: From Research to Results Book

I had been introduced to the 21 responsibilities of school leaders a couple years ago in one of my graduate courses, but I never followed up by reading any of Marzano's books. I finally got around to reading this one, and I found it clear and relevant even though it was published approximately 15 years ago. Although education is constantly shifting, the core seems to remain the same over time (for better or worse), so this text is still applicable. I appreciated the straightforward description of concrete actions school leaders can take in order to create a place that has increased student achievement. This is a great resource to refer back to over time. Side note: If I would have read this a couple years ago, all the talk about meta-analysis, factor analysis, correlations, and other research elements would have gone right over my head. Now that I am almost done with my PhD coursework, I actually understood the research process that was described!
