Even though principals do not directly educate students, their activities and decisions shape the teaching and learning that takes place in their schools. Understanding the relationships between how principals allot their time and educational outcomes could improve their training, selection, development, and evaluation. The main goals of our Faculty Innovation Grant are to 1) document how principals use their time, 2) examine differences in principal time use across various school settings, and 3) link principal time use to behavioral, emotional, and academic outcomes.
