This Evaluation Capacity Diagnostic Tool is designed to help organizations assess their readiness to take on many types of evaluation activities. It captures information on organizational context and the evaluation experience of staff and can be used in various ways. For example, the tool can pinpoint particularly strong areas of capacity as well as areas for improvement, and can also calibrate changes over time in an organization’s evaluation capacity. In addition, this diagnostic can encourage staff to brainstorm about how their organization can enhance evaluation capacity by building on existing evaluation experience and skills. Finally, the tool can serve as a precursor to evaluation activities with an external evaluation consultant.
