In November 2015, the National Policy Board for Educational Administration--a coalition of nine professional associations--adopted the Professional Standards for Educational Leaders (PSEL), a set of guidelines for the training, certification, hiring, evaluation, and supervision of school principals and superintendents. While it draws heavily from the earlier standards published by the Interstate School Leaders Licensure Consortium in 2008, PSEL is distinguished by a positive, asset-based approach to school management and leadership.
