An American K-12 cooperative educational services provider (“The Agency”) has an issue: partner school districts are saving money by building internal capacity for professional development, rather than fully utilizing expertise from the Agency. The aim of this evidence-based case study is to inform the Agency on capacity-building for innovation. The researchers performed three separate rapid evidence assessments, followed by a standard systematic review process to synthesize findings across 31 studies. Key findings identified from the research include (1) organizational capacity and program evaluation lead to organizational sustainability, (2) agency leadership should guide strategic organizational change in order to establish a shared vision for evaluation and feedback, and (3) organizations benefit from practicing continuous and ongoing learning through feedback loops. The findings of this study may be generalizable to other similar educational service providers or non-profits looking to strengthen organizational capacity and partnerships.
