Collaboration as means for development purposes is a widely desired goal within educational organizations and encapsulates an array of different actors linked to school operations as well as interconnected practices. While this holds true, implementing collaborative structures is associated with multiple hardships and challenges in practice. The aim of this study was to explore processual aspects of collaboration between two interconnected practices in the Swedish school system: the compulsory school and the Swedish school-age educare, and through this exploration propose a framework for understanding how these aspects might affect collaboration between inter-connected educational practices. Designed as a qualitative study, individual practice studies through questionnaires were collected from teachers in the Swedish school-age educare and principals responsible for the educational program. The findings of the study highlight factors hindering and enabling collaboration (and cooperation) between the interconnected practices, and based on these findings propose a frame-work grounded in interorganizational relationship-theory as a tool for future research on similar collaborative processes.
