Overview
- Mexico’s Education Secretariat lists the national preinscription window for public basic education as February 3–13, 2026, including for Mexico City, according to the official calendar.
- Baja California’s online registration for the 2026–2027 cycle ends on Monday, January 12, covering preschool (1–3), first grade of primary and first grade of secondary, with 24-hour access and state support lines.
- El Heraldo de México reports Mario Delgado and the AEFCM announced a separate CDMX digital window from January 13 to February 27 with a staggered schedule by initial of the first surname, which differs from the SEP calendar cited elsewhere.
- Authorities indicated that if a parent misses the surname-assigned day in CDMX, the registration could be completed on another day within the reported window, according to that guidance.
- The process is free, primarily online, typically requires the student’s CURP and guardian contact details, allows school choices during registration, and results are published after the window to guide final enrollment steps.
