Identify the best person you will ask to write you a letter of reference. This could be an employer from a paid position or internship, or even a past professor. The person should be knowledgeable of your work ethic and skills in the medical field or in science-related classes.
Approach the person you plan to ask at a time when he or she doesn't appear to be busy, such as at the end of a class or a work day, or make an appointment to meet with the person if he or she has a hectic schedule.
Provide the person whom you are asking to write your letter of reference with a brief synopsis of the school and program to which you are applying.
Explain why you think the potential recommendation writer is an ideal choice for the task. For example, you could say, "Since you have supervised my work for over a year, worked closely with me and are a well-respected professional in the medical field, I thought you would be a great choice."
Reference your knowledge of his or her busy schedule, saying, for example, "I know you are very busy and I hope it would not be an inconvenience for you to write me a short letter of recommendation."
Suggest significant, specific examples of your work and skills that he or she can include in the letter to help jog your recommendation writer's memory.
Detail your reasons for entering the pre-med program so the person you approach for a recommendation knows you are serious about your intentions. For example, explain why you want to become a doctor or nurse, what it means to you and why it is important that you are accepted into the pre-med program.
Thank the person for his or her time and relay the pertinent details associated with the letter of recommendation, such as the date it is due and to whom it should be addressed.
