The Program Administration Scale® (PAS ®) is designed to reliably measure and improve the leadership and management practices of center-based programs—the only instrument of its kind to focus exclusively on organization-wide administrative issues. In the third edition, the authors share updated information supporting the reliability and validity of the instrument and make key revisions based on the recognition of whole leadership as the guiding framework for the effective administration of early childhood centers. In addition, the PAS indicator language was reviewed from a racial equity and social justice perspective. This edition reflects feedback provided by practitioners from across the country who have used the PAS for program self-improvement, research, training, college instruction, accreditation facilitation, quality monitoring, mentoring, coaching, organizational consulting, and policymaking.
