What you need to know
A cross-listed subject, also described as "joint," is a single subject that is offered by two or more departments. Each department has its own number under which students can register. One department serves as the owner, and its number is referred to as the “master." Non-master subject numbers are sometimes referred to as “child” numbers. The master-child construct is purely administrative and is not apparent in the published catalog. Only the owner may propose changes in Subject Proposal Management, but all participating departments must approve the changes before they are reviewed and given final approval.
Sample cross-listed subject
Note the identical listings but different subject numbers. The master subject number is 2.003 and the child number is 1.053.
