Letters of recommendation may be written in a classic format that includes an introduction, body, and conclusion. There may also be specific requirements for certain letters that you may need to follow. In most cases, however, any well-organized format will be acceptable.

Follow these steps to be fair to everyone involved:

* If you don't feel comfortable writing a reference letter, don't. A vague or fabricated letter might do more harm than good.

* Use words such as excellent, superior, instrumental, creative, innovative, efficient, dependable, articulate, meticulous, self-starter and confident.

* Always thank the recommender for being willing to write a letter for you. After the letter is sent, you might consider writing a short note expressing your thanks for the writer's willingness to help you achieve your scholastic or career goals.

* Make the ending statement strong without overdoing it. Undo praise can be viewed as biased or insincere.

this is not a sample, it is a guide :)
