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.
Use standard formal letter writing conventions to begin. A letter of recommendation is like any other professional communication, and follows the same general rules and guidelines. Place your address on the top right, followed by the date—spelled out. Below that, on the left, place the recipient’s name (if known) and address. Open the letter with a formal business greeting. Ex: Dear Ms. Smith, Dear Sir or Madam, (if you don’t know the recipient’s name)
