separate the men from the boys

Reveal true capability

To separate the men from the boys is to distinguish those who are truly capable from those who are not—to reveal who can handle real difficulty.

The phrase implies a test or challenge that exposes inexperience or weakness: This tournament will separate the men from the boys.

Despite the gendered language, it applies broadly to any situation demanding proven competence.
