Admission to a master's program generally requires a bachelor's degree in a related field, with sufficiently high grades usually ranging from B+ and higher (note that different schools have different letter grade conventions, and this requirement may be significantly higher in some faculties), and recommendations from professors. Some schools require samples of the student's writing as well as a research proposal. At English-speaking universities, applicants from countries where English is not the primary language are required to submit scores from the Test of English as a Foreign Language (TOEFL).Admission to a doctoral program typically requires a master's degree in a related field, sufficiently high grades, recommendations, samples of writing, a research proposal, and typically an interview with a prospective supervisor. Requirements are often set higher than those for a master's program. In exceptional cases, a student holding an honours BA with sufficiently high grades and proven writing and research abilities may be admitted directly to a Ph.D. program without the requirement to first complete a master's. Many Canadian graduate programs allow students who start in a master's to "reclassify" into a Ph.D. program after satisfactory performance in the first year, bypassing the master's degree.
Graduate students must usually declare their research goal or submit a research proposal upon entering grad school; in the case of master's degrees, there will be some flexibility (that is, one is not held to one's research proposal, although major changes, for example from premodern to modern history, are discouraged). In the case of Ph.D.s, the research direction is usually known as it will typically follow the direction of the master's research.
Master's degrees can typically be completed in one year but normally take at least two; they typically may not exceed five years. Doctoral degrees require a minimum of two years but frequently take much longer, not usually exceeding six years.
