[Comment] Residency growth in Mexico: expansion and alignment challenges

In Mexico, entry into medical residency depends on the National Examination for Medical Residency Applicants (ENARM, for its Spanish name: Examen Nacional de Aspirantes a Residencias Médicas), a highly competitive test administered by the Comisión Interinstitucional para la Formación de Recursos Humanos para la Salud (CIFRHS). Performance on the ENARM is closely linked to the quality, accreditation, and geographic location of medical schools, candidates from private and northwestern institutions often outperform those from public or southern schools, highlighting enduring disparities in medical education and access to postgraduate training.
