As noted previously, the Carnegie system actually has a lot of different classification options, today none of which share the labels the US News uses. US News instead lumps together various Carnegie classifications into its own buckets with its own labels and own history.
OK, so per Carnegie (2025), Bucknell is a Special Focus: Arts and Sciences college. What does that mean? Well, per the 2025 Technical Manual, it means this:
• Special Focus: Arts and Sciences
o This includes institutions that award at least 50% of their degrees in academic programs in the humanities, arts, and social sciences as well as generalized sciences. For more information, please see the 2025 CIP Code Map. These institutions are limited to only institutions whose Award Level Focus is baccalaureate.
OK, so what data did they look at? It is summarized here:
In terms of Award Level Focus, apparently 98.7% of Bucknell degrees awarded were Bachelor’s, 1.3% Masters. So that is indeed Baccalaureate-focused.
In terms of academic program mix for undergrad, 15.2% were Engineering and 12.8% Business stuff, which of course would not be true at “LACs” without Engineering or Business stuff. However, that still only adds up to 28%, so 72% was in other stuff. So apparently that means it had over the 50% necessary in HASS and generalized sciences to qualify as Special Focus: Arts and Sciences.
I think one of the lessons here is that basically, US colleges and universities can offer whatever they like at the undergrad level, and the possible mix they choose is not somehow dictated by the Carnegie system, US News buckets, or so on. The Carnegie system then tries to impose some sort of order onto the inherent chaos of the US higher education system, but as usual with such things, there are going to be all sorts of cases which are not typical for whatever classification that Carnegie put them in.
From a college choice perspective, then, what you really need to do is treat each institution as an individual, and determine if it makes sense for you as an individual in light of what it does or does not offer academically. At most, classifications like Carnegie might help you generate leads, but you should not at all feel bound to treat them as defining what makes sense for you as an individual. And that is all the more true with the US News buckets.
