In my opinion, SLO is an excellent school, especially for certain majors including business. It is very cost efficient and leads to many opportunities. It may also depend on what area your son wants to focus in while in college. Finance? IB? Accounting? Consulting? Tech? Entrepreneurship? I would say that if your son does accounting, it’s an excellent school that places students into the Big4.
However, I live in CA. It’s excellent for business here. I believe OOS tuition is around $20,000 not including room and board. Moreover, although someone can be very successful nationally or even internationally at a regional college like SLO or UPortland(where my son graduated with a BBA), the fact is that the job opportunities will often be connected in business to your internship, alumni network, contacts, and those who either know you or the school. For regional schools, the alumni network at Cal Poly will be both SoCal and NoCal, mostly. Maybe up and down the west coast, maybe. SLO is not a nationally known school in my opinion for most business, and it could be more challenging to find work than attending another regional college or state flagship school in your child’s future location. Many confuse Cal Poly with Pomona and it’s reputation although excellent in so many areas sometimes gets overlooked as simply being a CalState school since it’s not a UC school (although SLO is as hard to get into and as good a school as a top UC!)
You mention UGA, Florida, Indiana , CU_Boulder. All great schools. If your child plans to live in any of those states or in the south, it makes sense to attend very good to great schools like UGA or UF. If your son lives in Denver or the west coast, CU. Indiana Kelley has a very reputable business school, and probably depending on the business emphasis, may be advantageous nationwide (accounting, etc.).
Moreover, I’ve toured Cal Poly SLO and the area. Either you love it or hate it. I don’t think there’s much in between. Honestly, if you’re used to living in a big city with a night life and action, I don’t see this being the school to attend. The town is not diverse at all as compared to other cities in the Bay Area or LA. If you like the outdoors, hiking, maybe the beach although awfully cold in the central coast, and a small town vibe, then SLO might be a good option.
However, when my daughter toured SLO’s Orfalea after touring other schools like USC Marshall, or even my son’s school up at UP, or UCB Haas, there was no comparison. For the price it’s great, but you get what you pay for. The college is pretty large, over 9000 acres! there’s a lot of walking and some hills. The student population is larger than other regional schools at over 21,000 with nearly 3000 in the business school, and it’s building and resources were not updated, the building was crowded and looked like a maze, and there were so little study rooms for students to collaborate privately together. After our tour, we decided it was not for her and there were many other better options.
In my honest opinion, I personally would not recommend SLO out of the schools you mentioned if those schools are closer to the areas where he wants to live in or as good for his major or emphasis. It’s a great public school that’s reasonably priced but is considered the number one west regional university for a reason.
