A transformative evaluator must understand the nature of impact evaluation very well. The fundamentals of impact evaluation should be applied to transformational development programs when assessment of evaluation feasibility justifies the cost.
The transformative evaluator must also understand technical and ethical limitations of impact evaluation applied to TD programs. Go to page 8 in Evaluating Transformational Development Outcomes for some thoughts about this.
Future posts will examine impact evaluation in more detail along with possible alternative approaches that may be more illuminating. Your comments about points to explore are welcome.
