Any service work performed by students in clinical settings outside of regular academic hours is non-compulsory. Students are not required to work as part of their clinical practicum/rotations. Some students elect to work outside of the practicum hours. During practicum hours, students are supervised by a medical laboratory professional and students are not permitted to be used as regular staff during these times. Students are not reimbursed during the practicum. In special circumstances, some students, who have demonstrated competency, are permitted to perform procedures with supervision.
