Teaching certificates are also quite common, with 26 states insisting on it.
States like Alabama, Arizona, and Arkansas reflect the common trend of requiring both an advanced degree and a teaching certificate.
Colorado and Kentucky stand out by not requiring either. Specifically, Colorado's prerequisites include an Assessment, a Bachelor's degree, Education Preparation Completion, and Work Experience, while Kentucky's criteria encompass an Assessment, Education Preparation Completion, Field Experience, a Teaching Certificate, and Work Experience.
Across the board, leadership standards have become a cornerstone of principal certification, with at least 47 states and the District of Columbia formalizing these criteria. These standards often emphasize core educational pillars such as academics and curriculum, cited by 42 states, and the foundational mission and vision, noted by 38 states.
The path to principalship is also diversifying. At least 16 states have embraced alternative certification routes, offering dynamic entry points into the profession, and acknowledging that effective leaders may come from varied backgrounds. Moreover, 12 states empower specific entities to develop these alternative pathways, indicating a trend toward localized and specialized leadership training programs.
Impact of Effective Principals
The Wallace Foundation's report "How Principals Affect Students and Schools" highlights the importance of effective principals in student outcomes. The report found that a principal from the top quarter of effectiveness could lead to nearly three extra months of math and reading learning over a year. The impact of effective principals goes beyond student success. A good principal can also help with teacher retention.
"We're in need of good leaders," Ryan Wade – teacher at the Marvin E. Robinson School of Business and Management at Yvonne A. Ewell Townview Center – said to the Dallas Morning News. "I've seen what great leadership can do for our campuses as far as setting academic expectations, as well as creating healthy environments for students and faculty, increasing morale."
