Every family and every applicant assign different weights to various factors in picking a school.
When the time came to pick a school for D18, including the choice of three Top 20 schools, sports culture, school pride, endowment, alumni network, modern campus, etc. were all important to D18. At Michigan you walk to the stadium with 111,000 other football fans and they sell out basketball and hockey too.
D18 chose Michigan not only because they offer something around fifty (50) Top 10 programs, including CoE, Nursing, Kinesiology, Ross Business School and a slew of LSA programs, but also because sports, alumni network and school pride are HUGE advantages for her.
While both UCLA and Michigan each have about a total of 45,000 students total, Michigan’s endowment is $12.5 Billion versus the $2 Billion for UCLA. Money buys “stuff,” new and remodeled facilities, pay faculty and GSI’s more money, etc. UCLA has 10x the endowment that SLO has.
D21 chose SLO based on a specific program, Animal Science/pre-Vet, NOT because of sports (obviously), endowment, alumni network, food, or a modernized campus.
Lastly, I think your kid will get adequate access to professors at UCLA. My D18 at Michigan goes to office hours and such and has plenty of access to her professors. Will it be like a LAC? No.
Anyway, it’ll just depend on what’s important to your kid and your family.
