References are usually provided by letter or over the telephone. If a letter is required, your reference may ask you to write all or part of it. If reference sends you a copy of a letter of reference about you, save it for your records. If there is to be a telephone call, advise both parties of any unusual pronunciations. Written performance evaluations by supervisors may sometimes be used as a substitute reference.
Personalized references are always best.
Check to see the entity that made the inquiry received the reference. Let your references know the outcome and thank them.
