From the 2015-2016 California State University Handbook
"Students completing high school through homeschooling are expected to meet the same admission requirements as those of students attending traditional schools.
Homeschooling may be affiliated with high schools or public school districts. In those cases, courses presented for satisfaction of the college preparatory subject requirements must appear on the UC's A-G´course list.
Homeschooled applicants will be expected to meet designated transcript deadlines, as specified by each campus. Applicants may be asked to submit supplemental information, e.g. SAT subject examinations, ACT subscore, AP examinations, etc to document completion of CSU eligibility requirements."
