Already mentioned in an earlier post regarding most UC’s moving up in the US News rankings, but note that UCSC was the only UC to decrease despite being admitted to the prestigious Association of American Universities (AAU) in 2019. Membership is by invitation only. Excluding UCR and UCM, all UC’s are AAU members, which includes all Ivy League schools, Stanford, MIT, other elite private schools, elite state flagship public schools like Michigan, Minnesota, Wisconsin, Washington, Oregon, etc., totaling 63 US universities members.
Here is a link for AAU members including the 7 UC members with the US News 2020 rankings of all 63 members.
