I think when you are talking about engineering - short of the very top - and yes Purdue is almost at that level- any other school - does it matter?
Will Ohio State and Rutgers be ranked higher than Bama and Arizona. Probably. On the CC, we care about this. An employer may care that you went to CMU or Purdue - but outside of 10-12 schools, will they care where you went? I doubt it.
So to me, your son needs to find the right fit. Part of fit is finances.
So in that sense your Bama, AZ, even ASU, Ms. State, Arkansas, Missouri S&T, Michigan Tech, UAH, Florida Tech…these schools (with merit - don’t forget merit) - will make the grade financially. What about a school like Iowa State, Oklahoma State or doing something so off the wall - and in such a cool and awesome place if you’re outdoorsy - South Dakota School of Mines. Or New Mexico - supposedly great merit. And I see @eyemgh on here and when people talk budget, he talks Utah!!
If he goes to Purdue for his second major - does that get him to where he wants to be?
Listen, I’m a lot about pedigree. My son was into Purdue and got the rare $10K scholarship (I think it’s because he attended engineering camp there because his classmates with better #s who got in and went to UTK instead got nada). I wish my son was at Purdue. He declined because they over enroll and their housing is not good because of it. Bama has the nicest dorms you’ll ever see (Ridgecrest) - and he chose there for them (funny as he hated his year in the dorm).
Also, while a school like Bama may be low ranked, they’re bringing in more national merit scholars then pretty much anyone and they’ve got fantastic students in the high end majors - because they’re buying them in. With your son’s #s, it won’t be as lucrative but still affordable.
You ask about OOS - so it looks like Bama is 60%, Auburn and AZ 40% - so all very significant. Auburn is close to GA and I bet most come from there although I don’t know. Bama and AZ are definitely pulling from all areas of the country. My son’s first suitemate in Bama was from AZ and chose Bama over Baylor.
He can always apply to a few more. If you are chasing an overall cost, what’s another $500 or $1K in app fees - and I’m not even kidding. What if you apply to a school that just blows you away $$ wise. Or apply to no app fee schools - you can find a list on Niche.
btw - while I love pedigree, I have $70K-80K more in my pocket - plus whatever that grows to investment wise - and that has to account for something good - so chasing a name for sake of chasing a name - maybe not worth it. After all, I’m sure my stress levels will be a lot lower than other parents who sent their kids to a name who then realize - oh crap, what did i do to myself - and have to worry every night about that!!
One more thing about cost - don’t forget schools like Purdue have “surcharges” for engineering. This can run thousands.
Good luck.
