Here’s what I read on another universities website in search of a better meaning of what priority admission might mean.
“California Community College students that have earned a transfer associate (AA/AS-T) degree are guaranteed junior standing and priority admission consideration over all other transfer students when applying to a CSU baccalaureate (BA/BS) degree program that has been deemed similar to the student’s community college area of emphasis.”
