Course and Units Offering System

The Course and Unit Offering System (CUOS) manages offerings for courses and units and associated timetable requirements, exam requirements, UTEI collection and Blackboard site/community information. CUOS also manages the rollover of offerings and related information.

CUOS is the repository of course and unit offerings in all teaching calendars for the current calendar year as well as the next calendar year. A record of historical offerings is also retained. CUOS interfaces directly with Callista SMS.


To obtain a CUOS account, general staff need to email Callista Support detailing their requirements.

You can then access CUOS via the Staff Portal.
