Research has consistently shown that principals play a critical role in determining the quality of teaching, and in turn, student learning and achievement. Recent meta-analytic reviews suggest that effective principals are highly competent in the following areas: 1) establishing and conveying the school's vision, goals and expectations by modeling aspirational practices and promoting data use for continuous improvement; 2) building teachers' professional capacity by providing targeted and job-embedded professional development, protecting instructional time, and selecting educators who are the "right fit" for the school; 3) creating a supportive organization for learning by sharing and distributing leadership, understanding and building on diversity, and strategically acquiring and allocating resources; 4) facilitating a high-quality student learning experience by developing and monitoring curriculum, instruction, and assessment, and creating learning environments that are personalized, safe, and orderly; and 5) connecting with external partners who can support fulfillment of school goals, and building productive and collaborative relationships with families.
