Fulfilling HS language requirement with summer CCC course

My HS Sr. hasn’t fulfilled a 2 yr language requirement. An American Sign Language summer course at San Jose City College is approved to fulfill the 2 yr HS language requirement, can he take that after he graduates HS in June 2018? Will that allow him to start a TAG TAP or AA-T program application as he begins Freshman year at a CCC; or must he take college language classes during the school calendar year?
Thank you
