Calling all stakeholders: group-level assessment (GLA)-a qualitative and participatory method for large groups.

Group-level assessment (GLA) is a qualitative and participatory large group method in which timely and valid data are collaboratively generated and interactively evaluated with relevant stakeholders leading to the development of participant-driven data and relevant action plans. This method is useful across a wide range of evaluation purposes in many environments. GLA involves bringing a large group of participants together to build a common database through the co-identification of relevant needs, judgments, and priorities. The GLA process proceeds through the following seven steps: climate setting, generating, appreciating, reflecting, understanding, selecting, and action. This article describes the methodological development and process of conducting a GLA and its various applications across the evaluation spectrum. We highlight several exemplars where GLA was used in order to demonstrate the particular nuances of working with different sizes and types of groups and to elaborate on our learnings from the wide applicability of the method.
