2. Letters of Evaluation
The SNS has been involved in optimizing the evaluation of medical student applicants. Both applicants
and programs value high quality letters of evaluation and recommendation (LOE/LOR). Over the past 3
years, Neurosurgery has piloted and collected data on letter templates. We continue to optimize the
SNS template and educate programs and supervising faculty about its use, in order to develop a fair and
balanced evaluation which is meaningful for programs evaluating applicants. In alignment with the
published data and the SNS recommendation to undertake 1 Home and 1-2 External AI rotations, the
SNS recommends that each applicant obtain the following recommendations:
• One (1) Home program: SNS Standardized Home Letter of Evaluation (LOE)
• One to two (1) External programs: SNS Standardized Away Letters of Recommendation (LOR)
• One (1) letter of any kind
At each program, letters using the LOE/LOR standardized format may be written by an individual or by
an evaluation committee, which will commonly involve the department chair, PD, and/or core education
faculty who have worked with each applicant. LOE/LORs should provide a fair and balanced evaluation
of each applicant. Importantly, the comparator group should include all students who have rotated with
the department in the past 3 years.
The final letter will often come from any individual mentor at the home or external rotation programs
who knows the applicant well, from a clinical, research, or non-neurosurgical perspective. It may be
appropriate for this letter writer to use the LOR template or to write a traditional free-form letter. This
can be determined at their discretion.
In alignment with AAMC recommendations, the SNS recommends that all faculty who review
applications, write LOE/LORs, and participate in interviews should undergo implicit bias and diversity
and inclusion training every 12 months.
3. Preference Signaling
In 2022-23, Neurosurgery participated in the 2022-2023 Supplemental Application Pilot. The vast
majority of Neurosurgery applicants and programs participated in the pilot, and many aspects of the
supplemental application are incorporated into the core ERAS application in 2023-24. Preference
signaling was an important aspect of this pilot program.
Based on AAMC data and SNS Post-Match survey responses, preference signaling had value for the
majority of Neurosurgery applicants and programs. Data from other specialties revealed the potential
for increase in value to both applicants and programs by moving to a high-signal model. For that
reason, Neurosurgery will offer applicants the use of 25 signals in the 2023-24 match. Per AAMC
guidelines, all applicants should signal programs where they have rotated (home programs or away AI
rotations) if applicants remain strongly interested in those programs after their rotations.
