Internships offered by many principal-training programs fail to adequately prepare school leaders. They may lack hands-on activities tied to improving student learning, high-quality mentor relationships, or a chance to gain experience in real leadership situations. In this report, the Southern Regional Education Board evaluates more than 60 internship programs within its states and urges policymakers, universities and school districts to create apprenticeships that better prepare aspiring principals for the current demands and expectations of their jobs.
