Editorial: Editors’ introduction

Across this issue of PDS Partners: Bridging Research to Practice, a clear thread emerges: professional growth is most powerful when it is reciprocal, embedded and intentionally structured within school–university partnerships. Taken together, these articles move beyond viewing teacher preparation as a unidirectional process and instead position it as a shared, evolving ecosystem in which preservice teachers, practicing educators and leaders co-construct knowledge, practice and identity.At the center of this issue is a vision of Professional Development Schools (PDS) and school-university partners not simply as sites of teacher candidate placements but as relational and intellectual communities. These communities are sustained through three interconnected pillars:Together, these pillars illuminate how partnerships can cultivate not only competent educators but also confident, reflective and connected professionals prepared to lead within complex educational systems.The first pillar foregrounds the idea that meaningful partnerships must benefit all participants. Across these studies, professional learning is not delivered – it is co-constructed, resulting in strengthened practice, leadership and professional identity.Norris and Doyle (2026) argue in “Elementary Teachers' Perceptions of the Impact of Mixed Book Study Group on Their Practice and Literacy Leadership Skills” that collaborative professional learning serves as a catalyst for both instructional improvement and leadership development. Drawing on a qualitative study of teachers engaged in mixed book study groups, the author shows how structured, teacher-led discussions centered on professional texts deepened participants' understanding of literacy practices while simultaneously building their confidence to lead professional development. Teachers not only engaged with research but also translated it into actionable classroom strategies and shared leadership within their schools. Importantly, the study highlights how adult learning principles, relevance, collaboration and reflection create a climate where teachers develop both expertise and agency. In this way, the work demonstrates that literacy leadership emerges through shared inquiry rather than hierarchical training.Extending this emphasis on shared professional growth, “Inservice and Preservice Teachers' Collaborative PDS Learning Walks” by Rombach and Guy (2026) positions collaboration as a driver of collective cognition and professional culture. Through Learning Walks, preservice and inservice teachers jointly observe classrooms and engage in non-evaluative, strengths-based conversations about practice. The findings reveal that these shared experiences foster collegiality, disrupt traditional hierarchies and promote a sense of mutual respect and contribution. Participants reported increased workplace positivity and a deeper appreciation for collaborative problem-solving. By positioning all participants as contributors, Learning Walks reframe professional development as a shared intellectual endeavor, strengthening both individual practice and collective capacity.From a systems perspective, Curtis, Mishnick, they cultivate professionals across the career span who are confident in their practice, connected to their communities and committed to continuous learning. As the field continues to navigate complexity and change, this issue of PDSP offers a clear direction forward: strong partnerships–intentionally designed – have the power to transform both practice and profession.
