At Mainstay, we are stanch to influence change through an evidence-based approach to policy and practice, and all our work is underpinned by the clear thinking and insight that comes from effective research. The evaluation examines the actual results of a policy, program, or project against what was expected, and is designed to ensure that the lessons learned influence future activity. Our approach reflects evaluation as a tool for learning and we work with partners to identify and articulate key lessons at every stage in the evaluation process.
