Measures of Instructional Leadership Expertise
(MILE)
A tool for identifying principals’ strengths and areas for growth

How can a school district identify the instructional leadership expertise of their school leaders in order to guide the planning of professional development for principals and district administrators? That question led researchers at the University of Washington to develop the Measures of Instructional Leadership Expertise (MILE) assessment.

The MILE assessment provides independent measures of a principal’s expertise in observation and analysis, providing feedback to teachers, leading professional learning, and one crosscutting skill of adopting an inquiry stance in their leadership.

“The MILE is the only assessment that I know of that provides a valid measure of proficiency in specific instructional leadership skills that matter most to improving teaching and learning.”

STEPHEN FINK, EXECUTIVE DIRECTOR, AFFILIATE PROFESSOR, UNIVERSITY OF WASHINGTON CENTER FOR EDUCATIONAL LEADERSHIP
