Did the OP identify which languages interested in? Many LACs will have the basic Romance languages, 1-2 Asian languages and perhaps Arabic, and may offer online or collaborative programs with other schools for additional languages. Beyond that, large universities are going to offer more breadth in different language offerings.
Lawrence and Wooster are great match/possible safeties, depending on scores. Lawrence has a lot of overlap, culturally, with Grinnell, in the sense there is a range of kids, not a dominant “type,” and a collaborative culture. Appleton is a small city, and with Lawrence’s Con, there is a vibrant music scene. Lawrence also seems generally open to College students participating at the Con – my kid had a long meeting with a faculty member on his instrument and they talked through how he might manage being at the College rather than the Con, participate in ensembles at the Con (basically, auditions are open to all students, not limited to Con students, and the “best” musician is placed in the “best” ensemble, and so down the list), and be a Varsity athlete. Lawrence also offers good merit money. We visited Wooster multiple times with my kid who was a recruited athlete there, and we did not see/hear about academic “intensity.” Yes, everyone talks about their IS, but I would not describe it as an intense academic environment. Nice kids, similar to Lawrence in that there is a range of “types.” Lovely campus, with a drop-dead gorgeous Science library, also gives merit money. I’ve also loved Mt Holyoke and Agnes Scott
I try not to answer threads in order to recommend my kid’s school, but Denison could be worth a look as it checks a number of boxes: Environmental Science department (with a 350 acre bio reserve on campus for research), a Poli Sci department strong in international/foreign affairs, including the Lugar Program International Track, which includes foreign language requirements, study abroad, and specific international-focused course work. Also, a blend of students and diversity of viewpoint – my go-to anecdote is that Reince Priebus and Jim Obergefell visited campus on back to back days, and Dems and Republicans attended both talks without protests to shut either speaker down. Granville is a lovely village/town, founded by MA abolitionists and looks like a charming New England village. Columbus airport is 25-30 min from campus, Ohio State is about 30 minutes away in the Short North, basically a college town. Relatively diverse student body – strong economic diversity, with about 20% Pell grant students plus lots of middle class kids drawn by merit money. Anyway, could be worth researching. Edited to add, also has an Educational Studies department/major, for what it’s worth in terms of OP’s interests, with classroom opportunities in nearby Newark/Heath which is a lower income area.
