Educational expectations and demands on the principal have changed markedly over the past few decades, so an updated set of standards or competencies is needed to effectively evaluate school principals today. Increasingly, many states require that administrators qualify for the Interstate School Leaders Licensure Consortium (ISLLC) certification. In 2006, forty-three states reported using ISLLC standards in some way related to administrator licensure. In Washington State, ISLLC standards set the direction and are the primary objective for developing course requirements and internship activities in principal preparation programs. Moreover, requirements for continuing certification for principals are job embedded, and based on ISLLC standards. This study aims to discover the extent to which the ISLLC standards are used in the evaluation of principals in Washington State, and to identify strengths or problems in current implementations of those standards.
