I am not well informed about the admissions policies at traditional women’s colleges, but as you’ve used the pronoun “he” to describe your child, check on the policies at Smith and Mount Holyoke, as those are both women’s colleges.
The first school that I thought of was:
- Delaware Valley (PA ): About 1800 undergrads
Some other schools that might be potential fits include:
- Ohio Wesleyan: About 1400 undergrads
- Berry (GA): About 2200 undergrads
- SUNY College of Environmental Science & Forestry: About 1600 undergrads and students can take classes at neighboring Syracuse
- SUNY Oswego: About 6k undergrads
- U. of Mount Olive (NC): About 2k undergrads
If you’re open to going further afield, these are some other schools that might be of interest:
- Southern Illinois - Carbondale: About 8k undergrads
- U. of Idaho: About 8800 undergrads
- U. of Wisconsin - Platteville: About 6k undergrads
- U. of Wisconsin - River Falls: About 4800 undergrads
- U. of Wyoming: About 8500 undergrads
