You’re probably not really looking to add schools for consideration. But…these are some schools with rugby programs that either seem as though your son would have a decent shot for TE or for sufficient merit aid to get the cost under $25k and none in the midwest!
Wagner (NY): TE set rate, 11-40% receive; cost with TE set rate would fall below $25k. Offers majors in music ed, fine and studio arts management, and music performance. About 1600 undergrads. On Staten Island so close proximity to New York City and water.
Marywood (PA ): TE full tuition, 11-40% receive. Offers majors in music performance, music ed, music therapy, and fine & studio arts management. About 1700 undergrads. Many outdoor opportunities available.
Salve Regina (RI): TE set rate, 11-40% receive; cost with TE set rate would fall below $25k. Offers majors in music and music ed. About 2100 undergrads and has a well-reputed sailing program.
U. of New Hampshire: Offers majors in music ed, performance, composition (and can do B.A. or B.M.). The net price calculator asks for GPA & test scores, so you should get an excellent idea of what type of merit aid would come. Has 11k undergrads. Near a bay and within a half hour of the Atlantic Ocean.
West Chester (PA ): Offers majors in music ed, performance, or music therapy and there is a minor in music production as well as jazz studies. 14k undergrads. Price is just under $30k before any merit aid, and I definitely think he’d have a shot at merit here. In close proximity to Philadelphia.
Nazareth (NY): TE full tuition, 11-40% receive. Offers majors in music history/literature/theory, music management, music performance, music ed, music theory & composition, and music therapy. About 2k undergrads. It’s in close proximity to both the Great Lakes and the Finger Lakes.
As a school that’s extremely likely to be affordable, there is Molloy (NY). It’s classified as a commuter campus, though, and only about ¼ of freshmen live on campus. This would personally give me pause, but it’s a TE full tuition school that grants TE to 91-100% of candidates. It offers majors in music, music ed, and music therapy and there are about 3200 undergrads. It’s on Long Island so it also has close proximity to New York City as well as water.
