We use a rigorous audit process. 100% of the households we enroll are audited by a second field team that operates completely independently from the team responsible for enrollment. Senior staff audit a smaller proportion of recipients. We also call our recipients after sending them money to learn more about their experiences. To date, 1% of recipients called report paying a bribe to a village official, and less than 1% report paying a bribe to a mobile money agent.
