The Comprehensive Assessment of Leadership for Learning (CALL) is a multi-source assessment of distributed instructional leadership. As part of the validation of CALL, researchers examined differences between teacher and leader ratings in assessing distributed leadership practices. The authors utilized a t-test for equality of means for the various responding groups on CALL and identified the areas of leadership practice that yielded the greatest and smallest differences between teacher and leader ratings. The authors discuss the similarities between leadership practices that yielded these differences. The authors discuss implications for leadership practice and suggest further research opportunities based on the findings.
