@youcee Certainly for my D and her friends, most schools with separate engineering applications (either to a separate school or individual major) said their acceptance rates were lower than the school’s main LA/AS college. Most of the time the engineering schools were much smaller (ie. had less admits) as well and the average stats were higher. Some schools actually break out the apps and admissions so you can search indvidually, but many don’t.
If you are asking in terms of a kid applying in the next year or two, it is something to be very careful/well educated about. Two of D’s academically strong friends found themselves with really limited options after they failed to “handicap” their admission chances for the engineering schools and went off the more general school stats. My D found she really had to change how she looked at schools, both for the individual programs (not all engineering schools are created equal) and chances of admission.
