Just click on the name of any of the 16 prep schools (USNA athletic & scholarship partner schools) to go directly to that school’s website.
I clicked on the last school listed. While it is only about one third boarding, it (Wyoming Seminary) does offer high level athletics, arts (including Jazz Band), and academics.
Remember, it is important to confirm percentage & number of boarding students as well as number of PGs attending each year for any school under consideration. Also, ask about specific, required PG only courses (typically just two or three including PG English).
