This is an excellent question. The Letter of Recommendation should include a brief statement of how the recommender knows you (e.g., the nature of your relationship), how long they have known you in that capacity and anything else the recommender can say that might shed light on your ability to perform, as compared to other individuals, at the institution. The recommender can also feel free to include anecdotes or specific examples of your performance that will be illustrative to the committee. If the recommender is an alumni or has any other connection to the institution, he or she should indicate that as well. Best of luck!
