Randomised controlled trials (RCTs) aim at measuring the impact of a given intervention by comparing the outcomes of an experimental group (receiving the intervention) and a control group (not receiving it), to which individuals are randomly assigned. It is a useful quantitative method of ex ante evaluation, to test the impact of a program at a stage when it has not yet reached the totality of its target population (making the control group possible).
