With few exceptions, when a teacher is first hired by a school board, he or she is hired as a daily occasional teacher, working on a casual “as needed” basis. As required by Regulation 274, the Durham District School Board lists all qualified, certified, occasional teachers (OTs) on their website in the employee portal. There are two (2) OT rosters: the elementary OT roster and the secondary OT roster. Occasional teachers with qualifications to teach in both the elementary and secondary panels may be hired to and appear on both rosters. Each roster includes the names of all occasional teachers, listed alphabetically, hired by the DDSB for that specific panel, the OTs date of hire, and a summary of his/her teaching qualifications. The rosters are updated on a regular basis.
