This Principal Quality Practice Guideline (PQPG) represents a first step in a process to develop a framework for quality school leadership in Alberta. It includes a statement on Principal Quality Practice and seven leadership dimensions, with supporting descriptors, reflecting the Alberta context. The PQPG is to be used as a basis for many activities including: principal preparation and recruitment, principals' self-reflection and daily practice, principals' initial and ongoing professional growth and principal supervision, evaluation and practice review. It also provides a reference for faculties of education in developing and delivering principal preparation programs, for teachers and vice-principals who are preparing for school leadership roles, for beginning principals in their efforts to meet stakeholder expectations and for superintendents in their supervision and evaluation of principals.
