Recommendation paper

A recommendation paper or paper of recommendationis a letter 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. Recommendation papers are almost always specifically requested to be written about someone, and are therefore addressed to a particular requestor. Letters of recommendation are typically related to employment, admissions to institutions of higher education or scholarship eligibility.
