Implemented in September 2019 at Kent Institution, the Onboarding Program is intended to support the transition of new Correctional Officers (COs) from Correctional Service Canada’s (CSC) Training Academy to the correctional environment. Mentor support and structured shadowing are available during the first year of a CO’s employment, providing guidance from senior employees intended to emphasize values and ethics. The current research surveyed new COs at Kent Institution participating in the Onboarding Program and at three control group sites (Atlantic Institution, Edmonton Institution, and Port-Cartier Institution) participating in traditional On-the-Job Training (OJT). This research is a collaboration between the Research Branch and the Learning and Development Branch of CSC.
