Overview

• Under Florida’s HB733, districts cannot begin before August 10 and must deliver at least 180 days of instruction totaling 720 hours for elementary students and 900 hours for higher grades, leading most schools to open on August 11.
• Texas school districts exercise autonomy in setting start dates, planning their calendars to begin classes between August 4 and 15 and determining local holiday and vacation schedules accordingly.
• Mexico’s SEP published a centralized September 1 start for the 2025–26 basic education cycle with 185 student instruction days, 190 teacher days for technical-pedagogical sessions and national breaks including a Consejo Técnico puente from September 26–28 and winter vacation from December 19 to January 12.
• Higher education institutions also vary calendars, with UNAM’s semester opening on August 11 and IPN’s school-based programs resuming on August 25.
• The finalized schedules underscore contrasting governance models: legislative mandates in Florida, local autonomy in Texas and a uniform national calendar in Mexico aligned with President Sheinbaum’s education reform agenda.
