Why Mexico's school calendar can catch relocating families off guard
Families moving to Mexico from countries with a September-to-June or September-to-July academic year, or from the southern hemisphere with a calendar-year school year, often assume Mexican schools will follow a broadly similar pattern. In practice, the great majority of private schools in Mexico, including those with a strongly international academic identity, are incorporated to the SEP and therefore follow the officially mandated Mexican school calendar, which generally runs from August through to late June or July rather than matching either of these more familiar patterns exactly.
Because specific start and end dates, and the timing of breaks, are set and can shift somewhat from year to year at the national or state level, always confirm the exact current calendar directly with any school you're considering rather than relying on a general expectation of when the year starts and ends.
The SEP academic calendar in outline
The Mexican Secretaría de Educación Pública (SEP) publishes an official academic calendar each year that SEP-incorporated schools generally follow, structuring the year from around late August through to early or mid-July, with the year usually broken into several evaluation periods rather than the two-semester or three-term structures more familiar in some other countries. Within this broad shape, the school year includes scheduled breaks around key national holidays and a longer break over the northern hemisphere summer.
Because this guide covers the general shape of the calendar rather than exact dates, which can shift from year to year and can also vary slightly between states, always request the current official calendar from any specific school directly, ideally as one of your first questions when researching schools.
How international-programme schools handle calendar alignment
Schools that layer an IB, British or American programme onto the SEP base generally still follow the underlying SEP calendar for their overall term structure, since SEP incorporation requirements apply regardless of which additional international programme a school offers. Some schools with a strong international identity may adjust minor details, such as the exact placement of a mid-year break, or add supplementary scheduling for specific international assessment periods, but the broad August-to-summer shape generally still applies. Our IB, British and American schools guides for Mexico go into more depth on how each pathway is structured within this calendar.
National holidays and scheduled breaks
Beyond the main summer break, the Mexican school calendar includes breaks around significant national holidays and observances through the year, along with a break in the December period covering the winter holidays and typically a shorter break in the spring. The exact timing and length of these breaks are set within the official SEP calendar and can shift slightly from year to year, so treat any specific dates you've seen elsewhere as indicative rather than fixed, and confirm the current year's calendar directly with your child's school.
Planning a relocation around the school year
If your family has flexibility over exactly when to relocate, arriving in Mexico close to the start of the SEP academic year in August generally makes the smoothest transition for a child starting at a new school, since this is when new cohorts typically begin together, orientation activities are most likely to be scheduled, and a child is less likely to be joining a class partway through material already in progress.
If a mid-year move is unavoidable, most established schools do still accept mid-year entries where space allows, but it's worth discussing directly with a prospective school how it supports a child joining partway through the year, including any catch-up support for content already covered.
Coordinating a school transfer between calendar systems
Families moving to Mexico from a school following a different calendar, for example a September-to-June northern hemisphere system or a calendar-year southern hemisphere system, should plan carefully around the transition, since the timing mismatch can mean a child either repeats several months of content or skips ahead compared with their previous school's pacing. Raise this directly with both the sending and receiving schools as early as possible, and ask specifically how the receiving school in Mexico typically handles transfers from calendar systems different from its own.
Leaving Mexico partway through the school year
The same calendar mismatch works in reverse for families expecting to leave Mexico again before their child completes a full school year on the SEP calendar. If there's a realistic chance of a further move during your time in Mexico, it's worth asking a prospective school early on how it documents progress and prepares transfer records for students leaving mid-year, so that a subsequent school elsewhere has a clear picture of what has been covered.
Not sure which schools fit your family?
Choosing an international school depends on your child's age, curriculum preference, location and budget. Tell us what you're looking for and we'll help you identify schools worth considering.
State-level variation in the calendar
While the SEP sets a national calendar framework, there can be some variation in specific dates or additional local observance days at the state level, and individual schools may also build in their own additional inset or professional development days beyond the official minimum calendar. This is another reason to treat any general calendar information, including in this guide, as a starting point, and to request your specific school's own published calendar for the year your child will attend.
Weekly schedule and school day length
Beyond the annual calendar, the length of the school day and the specific weekly schedule vary between schools and by grade level, with some schools offering extended-day options that include supervised homework time or extracurricular activities after the core academic day ends. If your family's work schedule requires a longer school day or wraparound care, ask a shortlisted school directly what options exist and at what additional cost, since this is a distinct question from the annual term calendar itself.
Public holidays affecting families beyond school breaks
Beyond scheduled school breaks, Mexico observes a number of national public holidays through the year that can affect broader family logistics, such as bank and government office closures relevant to paperwork like CURP registration or revalidación de estudios. It's worth being aware that some administrative processes may pause around these dates, which is worth factoring into your relocation timeline alongside the school calendar itself. Our how-to-apply guide covers this administrative paperwork in more detail.
Where to find the current official calendar
The most reliable source for the current SEP academic calendar for the relevant school year is the SEP itself or the specific school your child will attend, since schools are generally required to align with, and publish, the official calendar for their students and families. Ask your shortlisted schools to share their published calendar for the specific year you're planning around, rather than relying on calendars from a previous year or general online summaries, which can go out of date.
Building your moving timeline around term dates
Once you have a specific school's calendar in hand, it's worth working backwards from the start of the academic year to sequence the other pieces of your relocation, including visa processing, CURP registration, housing arrangements and shipping of belongings, so that your child can start school as close as possible to the beginning of the year rather than joining partway through. Our guide to moving to Mexico with children covers this wider settling-in planning in more detail.
A practical framework for planning a move around the calendar
Steps to sequence backwards from term start
- Confirm the specific school's published calendar for the relevant year
- Work backwards to set target dates for visa, CURP and revalidación steps
- Arrange housing with enough buffer before term start to settle in
- Plan travel or shipping to arrive at least a few weeks ahead of the first day where possible
- Confirm orientation dates separately, since these sometimes precede the general term start
Once you have a target school and its published calendar in hand, work backwards from the first day of term to sequence the rest of your relocation: visa and residency steps, CURP registration, housing, and shipping or travel arrangements. Building in a buffer of at least a few weeks before term start, rather than planning to arrive on the exact date, gives your family time to settle housing and logistics before also managing a child's first days at a new school.
Weighing a mid-year move against waiting for the new academic year
Families sometimes face a genuine trade-off between an employer-driven start date that falls mid-year and the smoother option of waiting until the following August. There's no universally correct answer: a mid-year move can work well for a younger child or a school experienced with international transfers, but it carries more academic catch-up risk for an older child partway through content-heavy subjects, particularly at IB, A-level or AP stage. Discuss the specific implications directly with a prospective school before assuming either option is automatically better for your situation.
Caveats on relying on general calendar information
Because this guide describes the general shape of the Mexican school calendar rather than a specific year's dates, treat any dates you encounter online, including in general reference material, as indicative until confirmed by your specific school. Calendars can also be adjusted during the year for reasons such as public health guidance or extreme weather, so it's worth asking a school how it communicates any such changes to families, particularly international families who may not be following local news as closely as long-term residents.
How exam schedules interact with the annual calendar
For students in exam-track years, whether IGCSEs and A-levels, IB Diploma examinations, or AP tests, the timing of external examinations is generally set by the relevant exam board or the IB itself and sits within, rather than replacing, the broader SEP-aligned school calendar. This can mean a distinct exam period, sometimes with an adjusted timetable for students not sitting exams, layered onto the standard calendar in the final months of the school year. Ask a shortlisted school specifically how it structures the exam period for the relevant programme, including any study leave arrangements, since this can differ meaningfully from the general term calendar most families first research.
Aligning family holidays and travel with the school calendar
Many expatriate families in Mexico plan trips home or elsewhere around the school calendar's scheduled breaks, particularly the longer December and summer periods, given that travel during term time can mean a child missing meaningful class time and, in exam years, potentially assessment deadlines. If your family expects to travel during term time for reasons such as visiting relatives abroad, it's worth asking a shortlisted school directly about its policy on term-time absence and how much flexibility it offers, since policies and attitudes toward this vary between schools, with some considerably stricter than others, particularly in the senior exam years.
Coordinating term dates across the whole family
Where a family has children in more than one school, or a child moving between school systems mid-year, term dates rarely line up neatly. A school following the Mexican SEP calendar, an international school on a northern-hemisphere academic year and a school abroad that a sibling is finishing at can each publish different start dates, holiday weeks and examination periods. Collect the published calendars for every school involved as soon as they are released, map them onto a single shared family calendar, and identify in advance the weeks where cover will be needed because one child is on holiday and another is not. The same exercise helps when booking flights home, since the cheapest travel windows rarely coincide with every school"s break, and schools generally expect absence requests around examination or assessment periods to be made formally and well in advance.
Frequently Asked Questions
When does the school year in Mexico generally start and end?
Most SEP-incorporated schools follow an academic year running roughly from late August through to early or mid-July, though exact dates are set annually and can vary slightly by school and state. Confirm current dates directly with your school.
Do international-curriculum schools in Mexico follow a different calendar?
Generally no. Schools offering IB, British or American programmes are still typically incorporated to the SEP and follow its overall calendar structure, though minor scheduling details can vary by school.
Is it better to move to Mexico at the start of the school year?
Generally yes, arriving close to the August start gives the smoothest transition, though most established schools can accommodate mid-year entries where space allows.
Can school calendar dates vary between Mexican states?
There can be some state-level variation and school-specific additional days, so always check the specific calendar published by your child's actual school rather than a general national summary.
What happens if my child needs to leave a Mexican school mid-year?
Discuss this early with the school so it can prepare clear transfer records and documentation of what has been covered, which helps a subsequent school pick up smoothly.
How long is the main summer break in Mexico?
The main break generally falls in the northern hemisphere summer, but exact length and dates are set annually by the SEP calendar and by individual schools, so confirm current dates directly.
Do all schools in Mexico have the same length school day?
No, school day length and any extended-day or wraparound care options vary by school. Ask a shortlisted school directly if this matters to your family's schedule.
Where can I find the official current school calendar?
The SEP publishes an official calendar, and your prospective school should be able to share its own published calendar for the specific year your child will attend.
