LAC = Liberal Arts College as mentioned above.
Usually such schools are small, under 3,000 is as good a cut off as any. Usually, but not always, such schools focus on a liberal arts education which may or may not include business (usually not) and engineering. Such schools may or may not, usually not, have curriculum for computer sciences but probably will have programs for hard sciences like chemistry.
They are usually private.
They are usually expensive.
You might get a lower COA with merit aid and other aid.
They usually will not emphasize or focus on revenue generating sports like football but might play hoops.
The athletics programs they do have are for the average athlete not the freaks of nature (I say that as a compliment believe it or not).
LAC’s might be a better for students who are a little bit socially challenged. Go ahead and shoot me but you know it is true. LAC’s would not necessarily be a good fir for someone who wants Greek life, parties, huge dorms, etc. for better or worse. Some people are okay with all that as part of maturing and growing up other parents/students want nothing to do with that. I, for example, went to a big public football playing school after going to a CC for the first two years and enjoyed the football but wasn’t interested in the drunken frat parties and booty calls.
One possibly down side to a LAC is you are living in a bubble not in the real world, in some cases, and not as prepared for the real word where, shockingly, you have to interact with people of all strips not just the cookie cutter ones who looked pretty much like you did at the tiny expensive LAC.
Proponents of LAC’s like to post data suggesting that LAC degrees, even though significantly more expensive to get, and that doesn’t even include grad school, earn as much as business, engineering and other vocational degrees like computer sciences but that data needs to be questioned if one thinks critically and without bias. I’m not saying all LAC’s work at Starbucks but if you major in psych with a minor in eastern European women’s studies and sociology you shouldn’t be surprised later if you have a hard time paying off your students dents without government welfare.
