Course Numbering

Current Course Numbering System

Most courses at Los Rios Community College District follow this numbering system:

Course Numbers 1 to 99

Developmental or basic skills courses. These courses are for credit but do not count toward an associate degree or transfer credit.

Course Numbers 100 to 299

Courses that apply toward an associate degree but are not transferable to a four-year institution.

Course Numbers 300 to 499

Courses articulated for transfer to four-year institutions, meeting major, general education, or elective credit requirements.

New Common Course Numbering System

Starting in Fall 2025, Los Rios Community College District is adopting a Common Course Numbering (CCN) system (per AB 1111). This system assigns common course numbers for comparable courses across all community colleges in the state. The goal of CCN is to facilitate a smoother transfer of credits between colleges and four-year institutions. The CCN system uses the following structure:

Subject Code

Four-letter abbreviation (for example, ENGL for English).

Course Type Identifier

CCN courses begin with "C" but local courses do not (for example, C1000 vs. 300).

Course Number

Standardized 4-digit number (for example, C1000 vs. 300).

As an example, ENGWR 300 becomes ENGL C1000 after the CCN transition.

What This Means for Students

• Summer 2025: The current numbering system remains in place.
• Fall 2025: Some courses will transition to the CCN. See a full list of CCN courses at your college.
• Phased Transition: The transition will happen in phases, so you'll see both types of courses in the class schedule.

We encourage students to check course listings carefully and consult with academic counselors to ensure a smooth transition.
