The California Community College system is implementing a student-facing Common Course Numbering (CCN) system, as required by Education Code Sections 66725-66725.5 through Assembly Bill No. 1111 (Berman), to be completed by July 1, 2027. This system will create common course numbers for comparable courses across all community colleges in the state, facilitating smoother transfers to four-year institutions and reducing unnecessary credit accumulation. By maximizing credit mobility, the CCN system will enhance equitable transfer opportunities and support student success by helping students build cohesive academic plans, understand course transferability, and make informed course selections. This collaborative effort involves faculty, administrators, staff, and system officials to ensure the best outcomes for California community college students.  (Source: ASCCC)

It is important to you if you have taken courses at any California Community College prior to Fall 2025 because course numbers and titles may have changed and you do not want to accidentally repeat the same course.

When colleges update courses, they do it during an academic year. Fall 2026 is part of the 2026-2027 academic year. So each phase will roll out courses during the fall semesters.

Courses identified as common between California Community Colleges are denoted with a "C" in the catalog number of the course (e.g., ENGL 120 is now ENGL C1000).

Some subject area prefixes have been changed to align with what is common throughout the state. At Grossmont-Cuyamaca Community College District Political Science (POSC is expanded to include courses in POLS), Psychology (PSY is expanded to include courses in PSYC), and Mathematics (MATH is expanded to include courses in STAT). 

Course articulation occurs at the college level, including for all CCN courses.  Students are strongly encouraged to speak with a counselor and consult ASSIST to confirm how a course will apply to their specific academic plan.

Courses that are not part of the CCN system will continue to fulfill general education, major preparation, and course-to-course equivalency credit under previously established transfer agreements between GCCCD colleges and four-year transfer institutions.

Yes. Courses that have not been changed may continue to transfer under previously agreed-upon transfer agreements between two-year colleges and four-year colleges.

No, you do not need to submit a modification of major. MATH 160 is equivalent to STAT C1000, so STAT C1000 will automatically count toward your degree requirement in place of MATH 160. 

No, you do not need to enroll in STAT C1000. MATH 160 is equivalent to STAT C1000, so MATH 160 will fulfill your certificate or degree requirements in place of STAT C1000. 

No, you do not need to take ENGL C1000. ENGL 120 is equivalent to a CCN college-level composition course. You can directly enroll in ENGL C1001 without needing to take ENGL C1000 or submit a petition for prerequisite clearance. 

Yes, you can receive grade alleviation for POSC 121 by successfully completing POLS C1000, as they are considered equivalent courses (the same). 

Yes, ENGL C1000H will be accepted in place of ENGL C1000. The "H" indicates it is an honors course. While GCCCD colleges do not offer separate courses for honors, they include honors within specific sections of a course. Your ENGL C1000H will still meet the certificate or degree requirement. 

Efforts are underway to align course articulation across California Community Colleges, as well as with the University of California and California State University systems, for Cal-GETC, major preparation, and course-to-course equivalencies. However, students are encouraged to consult ASSIST or speak with a counselor to confirm how the course will apply to their specific academic plan.
