A list of Adult Neuro-Oncology fellowship programs in the United States was obtained from the United Council for Neurologic Subspecialties (UCNS) and the Society for NeuroOncology (SNO) fellowship directories. Programs were analyzed based on 39 criteria grouped into six categories: Application Process, Academic Information, Contact Information, Program Information, Benefits, and Fellowship Life. Websites were assessed by author L.H. on two independent occasions between February and March 2024. Programs were categorized by Geographic Region based on the AAMC Geographic Preferences Map and by Program Type (e.g, university-based) according to their Neurology residency program designation on FREIDA. Analyses were performed using descriptive statistics.
