"Applicants must arrange to have two academic referees complete the Confidential Assessment Form and write an academic reference letter. Referees must be fullātime faculty members (normally with a rank of lecturer, sessional lecturer, assistant professor, or higher) at an accredited university. Please note that college instructors are NOT considered to be appropriate academic referees. Forms may be downloaded directly from the ORPAS Application.
Academic references are those professors, assistant professors and/or sessional lecturers who know you well enough to write an insightful reference that speaks to your academic capabilities, knowledge and skills."
