An important feature of professional development school (PDS) work is encouraging collaborative reflective dialogue that guides a partnership toward actualizing the possibilities for and mission of a PDS. This article provides a case "illustration" of a fictitious, exemplary PDS and a "protocol" that in combination can be used by PDSs interested in generating possibilities for their partnership development. As PDSs enter their second and third decades of existence, sustainability and accountability for authentic and deep partnership activities becomes increasingly complex to initiate and sustain. Given the importance of understanding the key features of PDS work, PDS educators benefit by using tools that help partnerships continually build important structures and roles as well as the "signature pedagogy" that often sets PDSs apart from traditional clinical placements and reflects the full mission of PDS work. This paper provides a pair of tools designed to generate discussion about PDS structures, roles, and "signature pedagogy" for PDSs interested in revitalizing or strengthening their partnership work.
