Who it's for

- Students in 9th–12th grade — check the official page for exact grade cutoffs before applying.
- Priority or eligibility for students in: NY. Some programs still take out-of-state applicants; read the fine print.

Typical day-to-day in programs like this
The following describes what participants generally do in conferences of this shape — not a confirmed schedule for National High School Model United Nations. Always check the official program page for the actual activities.
- Engage with a structured program in your field of interest.
- Meet peers and mentors you wouldn't otherwise cross paths with.
- Leave with something concrete — a project, credential, network, or a clearer sense of what to do next.
How to apply well
Selection is competitive but not unrealistic. A thoughtful application usually beats a decorated one.
- Start with the deadline: Spring. Work backwards — most students underestimate how long recommendations and essay drafts take.
- Read the official page twice before writing anything. Note the exact prompts and word counts.
- Answer the actual question. Reviewers read hundreds of essays; specificity beats polish.
- Submit at least 24 hours before the deadline. Portals crash. Files fail to upload. Give yourself the buffer.
Cost, funding & logistics
Cost and logistics kill more applications than eligibility does. Sort these out before you get emotionally invested.
- Format: In person in New York, NY.
- Duration: 4 days.
- There is a program cost. Check the official site for need-based aid; many similar programs offer partial or full scholarships and don't advertise them prominently.
- If travel or housing is required and cost is a concern, email the program directly and ask what aid is available. Programs rarely publish everything they can offer.
After the program
The most valuable thing you leave National High School Model United Nations with is usually not the credential — it's the two or three people you met and the one concrete thing you made. Keep in touch with your mentors and peers; they're the beginning of a professional network in International Relations, Political Science.
Add the program to your resume, but also write down (for yourself) what specifically you learned, what you'd do differently, and what question you now want to answer next. That reflection is what turns a summer into a direction.
