Model United Nations (MUN) isn't just another school thing, it's a taste of how the world really works. Teenagers become delegates, step into big shoes, and dive headfirst into debates about climate change, conflict, human rights, and more. It’s fast, a bit chaotic, and strangely addictive. You learn how to speak clearly, think fast, and work with people who don’t always agree with you. Sometimes it feels more real than real life.
It’s not all suits and speeches. MUN builds confidence, sharpens your instincts, and opens doors to new friendships from around the globe. If you're curious, these top 10 MUNs for high schoolers are worth checking out.
