Candidates are permitted 1 TDM exam attempt per administration year. If you did not pass the exam, you may reattempt the TDM exam in the following year. You cannot apply to consecutive exam sessions. Candidates may attempt the TDM exam a maximum of 4 times (which includes a maximum of 2 pass results).
Because the impacts of COVID-19 caused some PRA program intakes to be postponed and/or cancelled, the MCC and PRA programs have decided to extend the TDM exam result validity period from 2 years to 3 years for individuals currently holding a valid pass result. See the MCC for more information about TDM exam results.
