Measures of Instructional Leadership Expertise (MILE™)


You know there’s a strong link between student learning and instructional leadership. But do you have concrete data about your leaders’ strengths and areas for growth – a baseline that guides their professional learning?
The online MILE™ assessment provides independent measures of a principal’s expertise in four researched-proven areas. And the results will point to opportunities for strengthening practices that tie back to student growth.


  • Students get increased access and opportunities for meaningful learning
  • Teachers receive actionable feedback that’s tied directly to their students’ real needs and learning opportunities
  • Leaders establish a baseline, and focus adult learning on where it makes the greatest impact on student learning



MILE™ is designed for all school leaders (teacher leaders, assistant principals, principals and their supervisors, central office staff) who need an objective, easy-to-use and affordable tool to collect and analyze data.
“CEL provides a more comprehensive way of looking at instruction. CEL’s work helps us go deeper”

MILE™ measures four areas of instructional leadership expertise known to impact student learning: observation and analysis; providing feedback to teachers; leading professional learning and adopting an inquiry stance.
The responses to MILE™ are evaluated by specially trained instructional leaders using a rubric developed and validated by researchers at the University of Washington and Vanderbilt University. MILE™ is also commonly integrated into the Instructional Leadership Academy.
