UWC-USA: the international outlier
United World College-USA is unlike any other American boarding school. It enrolls roughly 230 students from more than 90 countries for the final two years of high school, teaches the full IB Diploma, and — critically — meets full demonstrated financial need, so a large share of students attend free or nearly free regardless of family income.
Admission does not run through the school. US students apply via the UWC USA national committee and international students through their own country’s committee, with selection weighted toward service commitment and intercultural capability. Because the process and calendar differ entirely from standard boarding admissions, do not assume the timeline in how to apply to boarding school applies.

New Mexico Military Institute
NMMI in Roswell is state-supported, which makes it one of the cheapest boarding options in the country: roughly $18,000–$22,000 for New Mexico residents and $32,000–$38,000 out of state, against a national private average above $60,000. It runs a high school and a junior college on the same campus, so students can begin college coursework in place.
As with military schools generally, it is a structured college-preparatory institution rather than a program for troubled teens — see military boarding schools. All states: best boarding schools by state.
