If the academic delivery structure begins at the programme of study level, a group of students that are enrolled on the same activities within a programme of study. The activities that a student set is assigned to are kept clash-free. Students who are on the same pathway might be allocated to different student sets, if some activities within their modules are relatively small. For example, two students might both enrol on the same chemistry module, but if the module's practical activity has a small planned size and several occurrences of it are needed to accommodate demand, then the two students might be enrolled on different practical activities. Student sets might have a total size of only one student if the capacity of some activities is limited to one (for example, a maximum of one student doctor in an operating theatre).
If the academic delivery structure begins at a lower level, a group of students that are enrolled on the same activities within a module. A student can be allocated to multiple student sets, which might be one for each module that they are studying. However, a student cannot be allocated to more than one student set for a module.
