In this article, the authors describe a key change from the First Edition to the Second Edition of Essential 3 of the NAPDS Nine Essentials. In the original Essential 3, the concept of "reciprocal professional development" was emphasized to honor PL opportunities that are led by either school-based faculty personnel as well as university-based individuals. No one entity or partner should always be seen as the "facilitator" or the "learner," but in fact all are capable of leading and taking the initiative for these efforts. The idea of reciprocal professional development is still beneficial. However, the Second Edition of Essential 3 puts more emphasis on the fact that all learners should embrace and participate in PL and learn together. The phrase reciprocal professional development, however, sometimes leads people to believe that either the university-based or P-12 school-based individuals should be facilitating the other group as opposed to the intended message of collaborative PL in which all participants and partners engage. The Second Edition of Essential 3 also references the idea of professional educators being guided by the spirit and practice of inquiry.
