A 2013 publication, The School Principal as Leader: Guiding Schools to Better Teaching and Learning, identifies five practices that effective principals use to cultivate better teaching and learning in their schools —from shaping a vision for the school to managing resources well. This article in Principal magazine shows how nine elementary school principals put those practices into action. One principal developed DVDs for parents to build support for his vision for the school; another wove instructional training into the school day to help teachers improve; a third helped teachers incorporate the demands of the Common Core State Standards into existing lesson plans. The nine principals are part of a professional learning community in The Wallace Foundation’s Principal Pipeline Initiative to help six school districts develop large pools of effective principals. Most come from challenging schools with much diversity and many low-income students. The article was written for the magazine by a Wallace-commissioned writer, H.J. Cummins.
