If a student doesnt have enough credits to graduate can highschool kick then out senior year in the state of California?

No, a California high school cannot kick out a student for lacking credits needed to graduate during their senior year, *unless* there are other disciplinary reasons for expulsion. Simply not having enough credits to graduate is not grounds for expulsion. The school is required to provide the student with support and a path to graduate, possibly including summer school or alternative programs.
