Well, if you apply to a LAC from a large university, the answer to that question should be clear.
For larger top universities, you don’t really have good reasons for transferring and that’s a key element in choosing applicants.
Academic reasons are pretty much the best. You may be swapping a large department for a small one, but the small one has Professor X and Professor Y and a specific focus that you want to have for your long-range goals.
If I understand your motivation correctly, you seem to be searching for greater academic engagement with faculty and peers. Because of issues at least partly related to scale, these opportunities do not seem to be as accessible as you would like at your current school. By stating this directly, you should be appealing to your potential transfer colleges as intellectual, sincere and honest.
As you’ve planned, getting applications out to a few schools seems like a great idea. You can further consider your decision after you’ve seen how you’ve fared.
I’d recommend, not incidentally, that you reserve your applications for colleges that appear to be reasonably transfer friendly. Some schools that technically admit transfer applicants accept so few of them so as to be nearly closed doors.
Wishing you success at your current school and, should you decide to make a change, with your upcoming applications, @Seastar98.
I would point out the fact that transfer students are not treated the same as freshmen students in terms of merit aid. Many scholarships offered are specifically for freshmen; transfer scholarships are rarer and for less money in my experience. But for need-based aid there’s not a huge difference
