I've been editing a whole heck of a lot of ERAS applications recently, so I thought I'd create a list of tips for those embarking on their descriptors:
1. Include relevant pre-professional accomplishments from college. If you conducted research, for example, list and describe it. Do not include high school achievements unless they were truly unique (worked at the White House, sang on Broadway ;)).
2. While you want to include many strong achievements, you do not want your ERAS to be so long that your reader is tempted to skim it. Be selective.
3. Keep your descriptors to approximately three to seven sentences. Fewer can look lazy and more can look self-indulgent.
4. Use full sentences. It’s a formal application, and you want to make your written materials as readable as possible.
5. Avoid abbreviations. Again, you want to be formal, and abbreviations you think are common might not be familiar to the reader.
6. Make sure you spell out your accomplishments clearly. If your reader doesn’t understand an activity, you will not get “full credit” for what you’ve done. Make no assumptions.
7. Write about yourself and your role – not an organization. For example, don’t use the space to discuss Physicians without Borders. Use it to discuss the specifics of your role at Physicians without Borders.
8. Use numbers to be persuasive. Saying that the conference you organized had 300 participants says it all.
9. Unless your PI won the Nobel, avoid using supervisors' and/or doctors' names in your descriptors as they will be meaningless to the majority of your readers.
10. Get help. Do not submit your residency application without having it reviewed. Don’t submit suboptimal materials for a process that is this important and competitive.
