You are required to have three letters of recommendation submitted on your behalf. The letters should be submitted by instructors in a discipline related to your proposed field of study who are in a position to analyze your abilities and academic promise. Letters may be submitted online or on paper via regular mail; online submissions are strongly preferred.
A recommendation letter or letter of recommendation, also known as a letter of reference, reference letter or simply reference, is a document in which the writer assesses the qualities, characteristics, and capabilities of the person being recommended in terms of that individual’s ability to perform a particular task or function. Letters of recommendation are typically related to employment (such a letter may also be called an employment reference or job reference), admission to institutions of higher education, or scholarship eligibility. Recommendation letters are usually specifically requested to be written about someone, and are therefore addressed to a particular requester (such as a new employer, university admissions officer, etc.), although they may also be issued to the person being recommended without specifying an addressee.
