Randomized Evaluations of Interventions in Social Science Delivery
Every year, millions of dollars are spent on evaluating development programs but these evaluations tend to focus on process: did the money go where it was meant to? How many teachers attended training courses? How many textbooks were delivered to schools? While tracking performance at this level is important, we should also be evaluating programs at a more fundamental level to find out whether, for example, training teachers or buying textbooks does more to raise test scores.
