At which point does a letter of recommendation become too old to use? A premed advisor once told me that letters of recommendation generally should not be more than a year old. I agree that the more recent a letter is written, the better. However, if I were to request an updated recommendation from someone who wrote me one a few years back, I am somewhat concerned that the letter won?t be as strong just because the recommender may have forgotten some of the details that make for a strong LOR (i.e., details that may be in the original rec letter). I realize that some professors may hang on to a copy of the letter they wrote for a student so that they can just update it if need be. But many just write the letter and send it off. I am primarily concerned with my recommendations that were written four years ago. My letter file looks like this:
Graduate science professor, May 2004
Non-science professor from undergrad, June 2004
MD who I worked with in the OR, September 2003
MD who I did research for, November 2000
Post-bac science professor, September 2000
Do you think the older letters will be okay in light of the recently written recommendations, or should I request my recommenders to update (and run the risk of the new letter not being as strong as the original)?
Thanks for your suggestions.
