The CSU offers more than 1,800 bachelor's (BA and BS)​ and master's (MA and MS) degree programs in some 240 subject areas. Many of these programs are offered so that students can complete all upper-division and graduate requirements by part-time, late afternoon, and evening study. A variety of teaching and school service credential programs are available throughout the CSU system. A limited number of doctoral degrees are offered jointly with the University of California and with private institutions in California.
