Purpose: This paper aims to provide details around Essential 8 of the Second Edition of the National Association for Professional Development Schools (NAPDS) Nine Essentials (NAPDS, 2021), which focuses on boundary spanning roles across university and P-12 school settings. Design/Methodology/Approach: This paper represents an in-depth look at one element of a policy statement of the NAPDS. The Nine Essentials were reviewed over a 4-year period through meetings, focus groups and symposia with various stakeholder groups. These provided context and information for both the revision of the policy statement and the writing of this article (and the other articles in the series). Findings: The intention of this series of articles is to provide a deepened understanding of the complexities of P-12 School and University partnerships. Each of the essential elements provides a framework for developing new PDSs and sustaining existing partnerships for the long term. Originality/Value: This is a reprint request.
