The decision process is a complex one which must take into consideration all of the factors which will be discussed here. Law schools vary in their individual guidelines for letters of recommendation. A law school may specify the number of letters required or may leave the number open. One school may specify academic letters only, while another may not specify the kind of letters required. Some require a Dean's Letter, although a far fewer than in years past.
Schools vary as to the form of the letter as well.
Each letter should be accompanied by a signed waiver form and enclosed in a sealed envelope with the signature of the letter writer over the seal. You must first determine the number and kind of letters that each law school requires. The best recommendations come from people who know you well and can size you as a potential law school student and lawyer. Although the recommender's rank may not matter, if a person of impressive rank can evaluate you up in this fashion, that is all to the good. Remember that law schools are institutions which are interested in your academic potential.
