We are responsible for coordinating and supporting departmental timetabling accesses, processes and systems enhancements. We UAT all systems before launch and ensure to deliver only the best of systems and products to our departments. With a strong customer focus, our team provides quality assurance services in order to facilitate data transfers and ensure that timetabling data and outputs meet policies and best practices.

What we do

User training and support

CTSO offers a range of training, drop-in sessions and learning resources to help departmental timetabling staff and administrators easily access and navigate the Celcat system, its tools and products. Training sessions are run by our experienced team who have also created learning resources such as video tutorials and help sheets that staff can refer to after the training session.

Policy and quality assurance

Timetabling support is the heart of what we do, we are passionate about improving timetabling and space sharing. We are continuously working with other departments for data integrity checks, policy advice and implementation. This is to help create and enforce better processes and practices that will enhance staff and student experience.

Timetabling best practice

Our team are here to support departments in every step of timetabling annual cycle. We provide support to departments from the very start of selecting data to complex data validation, installation and publication of annual Teaching and Exam Timetabling Build Plan. We provide manual and automated timetabling support and at specific periods of the academic year we update departmental preferred choices of publication windows and products.

System administration

CTSO works to protect departmental resource data, event category information and events by providing only authorised staff access to Celcat. We liaise closely with departmental administrators to update data and ensure data quality to agreed standards. We work with ICT to enhance synchronisation across systems, such as interfaces between Celcat, KX, SoV, Panopto and look to create more efficient, reliable and user friendly systems. This also includes systems where we do not yet have formal integration, such as Banner.
