Researchers identified a number of important considerations for districts seeking to revise the principal supervisor role. 

• Deep changes to the principal supervisor role require clear expectations for the focus of that role. This includes strong expectations for specific practices. 
• Districts must provide ongoing opportunities for principal supervisors to learn and refine their practices. 
• Principal supervisors first need  a deep, common understanding of high-quality instruction. Some PSI districts worked closely with supervisors on what they wanted students to learn and how they wanted teachers to teach.
• Principal supervisors need a deep, common understanding of instructional leadership practices. Some PSI districts worked with supervisors to support principals in learning specific practices. One example is data-based decision-making. Another is how to observe classroom instruction and provide teachers with feedback.
• Principal supervisors then need to know how to develop instructional leadership in principals.
• The district central office must ensure that it has the culture and capacity to support a redesigned principal supervisor role.
