This evaluation follows a random assignment (or ‘experimental’) design. Individuals participating in the pilots are randomly assigned to either an ‘action’ group for whom IAP participation is mandatory or a ‘control’ group for whom participation remains voluntary. The strength of this approach is that it permits the most robust evaluation of the effects of the mandate as it avoids the selection bias that can result with alternative approaches – other approaches rely on untestable assumptions.
