Common course numbering (CCN) makes it easier for students to transfer courses between community and technical colleges in Washington state. About a quarter of all community and technical college students graduate from a two-year college with credits transferred in from another college. Common course numbering eases that process, because equivalent courses are labeled the same across all colleges.
Academic Common Course Numbering
CCN was first implemented in 2006 and included mostly academic transfer, with a limited set of professional-technical courses.
Courses in the Common Course Numbering database are designated with the ampersand (&) symbol and a common 3-digit number and include:
- Academic transfer courses, as defined by the Intercollege Relations Council (ICRC) agreement
- Professional-technical aerospace/aviation maintenance and early childhood education courses
Professional-Technical Common Course Numbering
The professional-technical common course number (PTCCN) system was introduced in fall 2016 and resource pages are under development.
Professional-Technical Common Course Numbers (PTCCN) are designated with the letter "C" and a common 4-digit number. At this time, PTCCN courses are not part of the CCN online database, but this may change as the program evolves.
