Lapsed-In the Course Offering System (COS), if the course has not been offered for the past (7) years or if a program has been closed, the course will be considered “lapsed.”
Retired-When the version of the course has been discontinued in the curriculum, it is considered “retired.
Expired-The courses that are no longer offered in a Faculty’s curriculum and has an expiry date are considered “expired.”
In CMS, “inactive” is used and is equivalent to ‘retire’ in COS.
Retired courses in CMS were marked as such due to data quality issues in COS. For example, some courses were labeled as "Lapsed" without an associated expiry date, while others had overlapping term data—conditions that are not supported by the CMS system. However, all newer versions of these courses were successfully imported into CMS as either Active or Inactive, based on their current status in COS.
