A recommendation letter is 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. They are almost always requested to be written about someone, and are addressed to a particular requestor. It is important to know how to write a reference letter, as almost everyone is asked to provide a reference at some time during their career. You should explain your connection to the person you are recommending, including how you know them, and why you are qualified to write a reference letter to recommend employment. The letter should also include some specific information on the person you are writing about, including why they are qualified, what they can contribute, and why you are providing a reference letter. If necessary, use more than one paragraph to provide details. When writing a specific letter referring a candidate for a particular job opening, the reference letter will include information on how the person's skills match the position they are applying for. The recommendation letter and reference is often same and used interchangeably with the term "reference letter"; but, there is a difference between these two types. Letters of recommendation are very specific in nature and normally requested/required and are always addressed to an individual, whereas letters of reference are more general in nature and are usually addressed "To Whom It May Concern."
