Obtain the petition package from the Registrar’s Office web site and follow the instructions. The Registrar’s Office maintains an extensive web site informing students of procedures and process. Required documents generally include a letter explaining what you are petitioning for and why, documentation such as an Attending Physician Statement or anything else that supports the reasons you give in your letter, and for some petitions Course Performance Summary forms.  Documentation should ideally attest to the impact of the circumstances on you as it relates to the relief you are petitioning for. For example, simply stating that your grandmother died and providing a death certificate will likely not be considered compelling without also documenting that your grief was such as to severely impact your functioning. The complete petition, i.e. all the documents, should be submitted in one package by email to the Registrar’s Office at ropet@yorku.ca.
