The organization itself is an audit.

If a person can pass the written exam, their IQ is fine. If they can pass the interview, their emotional intelligence is fine. If they can pass the political review, their family background is fine. If they can pass the medical examination, their health is fine.

The men and women of marriageable age you encounter have also been vetted by the organization—they've at least passed checks on IQ, emotional intelligence, family background, and health. This means that when you form a family in the future, you'll face at least fewer of the complex and diverse problems found in society.
