In contemporary educational settings, school leaders and teachers face increased accountability and pressure to raise student performance. Utilising professional learning to develop individual and collective capability is a common feature of these settings. In Australia, there is evidence that many schools have implemented action research to support the improvement agenda. A significant part of this agenda is providing evidence of outcomes arising from the action cycles. Indicators of progress and outcomes provide evidence of improvement to external audiences and afford insights and feedback for participants, which assist in developing further plans to address improvement. This paper outlines the development and use of an interpretive learning framework, incorporating a two-part reflection tool, developed to assess the quality of action research projects conducted by teacher researchers in schools. To do this, individual school case accounts were initially developed from analysis of action project data. A thematic analysis was then undertaken and the emergent themes, together with pertinent action research literature, informed the basis of the tool and its two integrated elements: an innovation matrix and rubric. Both elements permit understanding of project strengths and areas for further development within individual projects.
