Qualitative research studies are used in our field to explore the complexity of teaching and learning. There are, however, persistent barriers to using results from qualitative research to inform policy in schools. There is a growing interest in education for integrating findings across qualitative empirical studies to unpack common threads that can serve as actionable recommendations for practice. We describe qualitative synthesis and its relationship to other research synthesis methods, identify a specific method, meta-aggregation, used to integrate research into practice, and share a critical appraisal protocol for in this method.
