As promised earlier, here is my guide to soliciting letters of recommendation or evaluation. One of the most stressful parts of applying to a health career program is the requirement to obtain letters from professors, mentors, and supervisors. Programs may have basic requirements (for example, at least two letters) or very specific demands (two letters from professors of science, one letter from a medical doctor, and one letter from a volunteering supervisor). Often, the stress results from inadequate preparation and waiting too late to ask potential writers.
