WIDA School Improvement System

Developed in collaboration with WIDA, the WIDA School Improvement System (WIDA SIS) measures the key practices that support teaching of English Learners (ELs). The resulting data informs the professional development needs in a school to support teachers in their effort to support all students in the classroom.

Four Domains CALL System

The Four Domains CALL System measures key instructional leadership practices at the school and district level that are aligned to the Four Domains for Rapid School Improvement framework developed at the Center on School Turnaround at WestEd.


CALL for Equity-Centered Leadership

CALL for Equity-Centered Leadership (CALL-ECL) is a research project focused on the critical distributed leadership tasks that enhance equity in schools. CALL-ECL functions like other versions of CALL in that it provides action-oriented data for school leaders to support improvement work. CALL-ECL data is equity-centered, and provides guidance to leaders across the school.

Mapping Leadership

In 2009, University of Wisconsin Professors Richard Halverson and Carolyn Kelley set out to develop a school leadership assessment tool with a unique approach to inquiry and survey design. The result, the Comprehensive Assessment of Leadership for Learning (CALL), is now being used across the country, and around the world, not only to assess school-wide leadership but to provide meaningful and timely feedback to school and district leaders. CALL’s distributive leadership framework, task-based approach to inquiry, and interactive formative feedback system show that “assessment” can be a meaningful experience for all involved.
