The role came up on a Friday in October. The father, a managing director at a global mining group, had been asked to lead the company's Latin America business. The base was Mexico City. The mother, a Mexican national who had grown up in Polanco, had been living abroad for fourteen years. She had not expected to return. The offer was structured for four to six years. They had two children, aged 10 and 8. The 10 year old was in year 6 at a strong British curriculum school in Dubai. The 8 year old was in year 4 at the same school. Both children were settled and the elder had been preparing for the school's year 7 entry assessment.

The family had three months to organise the move. The role started in mid January. The Mexico City school year ran on a US calendar, which meant the children would arrive mid year. The British curriculum option in Mexico City existed but was thinner than Dubai. The dominant international school choices in Polanco and surrounding neighbourhoods ran American curriculum, with a smaller number offering the IB Diploma at sixth form. The family had to decide whether to maintain British curriculum continuity by commuting further, or switch to American curriculum in a school the mother already knew from her own childhood.

The mother wrote to us before Christmas. The note was thoughtful and slightly conflicted. She wanted advice on whether returning to her old school for her own children would feel right. Our reply walked through the structural questions first. The personal question would clarify once the structural one was clean.

The brief

The non negotiable was settled in the first conversation. Spanish exposure. The mother wanted both children to gain working Spanish during the Mexico years. The children had taken Spanish as an optional language in Dubai but were not conversational. The Mexico schools would need to support active Spanish acquisition, not just offer it as a token language class. This filter narrowed the shortlist quickly. International schools in Mexico City vary widely in how seriously they treat Spanish acquisition for non Mexican families.

The second non negotiable was a strong learning environment for the elder daughter. She had been on track for year 7 at a competitive British school and the family did not want her academic trajectory blunted. American curriculum at international schools in Mexico City typically uses US grade naming, which mapped her year 6 into fifth grade entering sixth. The substantive curriculum content varied across the schools we discussed.

The third non negotiable, and the most surprising one to the parents, was about the family identity. The mother wanted the children to encounter Mexico as Mexicans, partially, alongside their international identity. This ruled out schools that operated as US enclaves with minimal local engagement. The family wanted a school where Mexican children, third culture children and visiting expat children formed a balanced cohort.

The shortlist

From the brief, four schools made the working list. The American School Foundation in Bondojito was the largest international school in the city, with a clean American curriculum and a balanced Mexican and international cohort. Edron Academy ran a British curriculum with bilingual Spanish provision and was the natural option for British curriculum continuity. Greengates School in Lomas ran a British curriculum with strong international cohort. Westhill Institute in Santa Fe ran a US curriculum with strong Mexican enrolment.

The family visited Mexico City for a week in early December. The mother spent two evenings showing the father neighbourhoods that mattered to her. The visits to the schools were spread across three working days. The mother led the school visits because she was the parent who knew the city. The father observed and asked the structural questions. Both children joined the visits, which the family later said had been one of the better decisions of the process.

The elder daughter responded most strongly at the American School Foundation. The fifth grade class she sat in was working at an appropriate pace. The Spanish for foreign students programme was structured into the timetable with five sessions a week and a fully bilingual buddy. The school had a meaningful Mexican enrolment alongside its international one. The library impressed her. She came out of the visit asking when she would start.

The younger daughter responded most strongly at Edron Academy. The British curriculum continuity gave her familiarity in week one. The bilingual Spanish was strong. The school felt smaller and warmer than the other options. The family had a working tension. Each daughter favoured a different school.

The decision

The family considered the two school split seriously. Two schools would mean two commutes, two parent meeting cycles, two sets of uniforms and twice the friend management. The household had absorbed similar complexity in Dubai when the children had been at the same school but in very different year cohorts. The arithmetic was manageable. The question was whether it was the right answer.

The conversation that resolved it took place in the hotel restaurant on the fourth evening. The elder daughter was articulate about why she preferred the American School Foundation. The Spanish programme felt like a real opportunity, the cohort was bigger and she wanted to start the curriculum switch decisively rather than postpone it. The younger daughter, asked the same question, said she did not really mind which school as long as her sister was nearby. The mother asked the younger daughter whether she would consider the American School Foundation if her sister was there. The younger daughter said yes.

The family chose the American School Foundation for both children. The trade off was real. The younger daughter gave up the British curriculum continuity she would have preferred. The family decided the cohort and Spanish programme weighting was worth it for the duration of the posting. The school accepted both children's offers within a week of the visit. The elder daughter would join fifth grade. The younger would join third grade. Spanish acquisition would be structured from week one for both.

The mother said in retrospect that her own emotional attachment to the city had blurred her early thinking. Edron Academy was the school many of her friends in Polanco still recommended. Her daughters' reactions had been the clarifying inputs, not her own nostalgia. The family lesson was that a returning parent should let the children lead the visit interpretation, not the other way round.

What changed

The family arrived in mid January. The first two weeks were busy with paperwork and house viewings. The school received both children in week three. The elder daughter's adjustment was visibly fast. The fifth grade teacher had been briefed on her British curriculum background and structured the first fortnight to identify learning gaps and strengths. Mathematics was ahead. Science was at level. Social studies were entirely new because Mexican history had not featured in her Dubai curriculum. The Spanish for foreign students programme moved her from greeting Spanish to conversational Spanish in eight weeks. By the half term she was choosing to speak Spanish to the cook at the family home.

The younger daughter took longer. The first three weeks were tearful. She missed her Dubai best friend with an intensity the family had not prepared for. The class teacher proposed a structured buddy intervention in week four. The younger daughter's buddy was a bilingual Mexican girl who lived three streets from the family. The friendship took. By the end of week six the younger daughter had three friends. By the end of the school year she had decided Mexico City was her home for now.

The mother re engaged with her own city in a way she had not expected. She had not lived in Mexico City as an adult. The first month was a quiet rediscovery. By month three she had two professional projects on the go, a renovation underway on a small flat she had inherited in Coyoacan, and a stronger relationship with her elderly parents than she had had during the Dubai years. The father took longer to settle. His role required regional travel and he was rarely in the city for more than ten days at a stretch in the first quarter.

Lessons for other parents

The family's reflection surfaced three lessons we see often. The first was that the returning parent dynamic deserves explicit discussion before the visit. A parent who grew up in the destination city carries assumptions that can dominate the family conversation. The mother in this case had to actively step back. Families with a returning parent should plan for that step back deliberately.

The second lesson was that Spanish acquisition is a real opportunity in Mexico City and most other Latin American postings. International schools vary widely in how seriously they treat second language for non native speakers. The right question is to ask for the weekly hours, the cohort size, the teacher qualification and the typical proficiency outcome at the end of year one. Schools that cannot answer specifically are signalling something. Our how to choose an international school guide covers second language acquisition in detail.

The third lesson was about the curriculum switch decision for younger children. The younger daughter had been the family's reason to consider British curriculum continuity. The American curriculum switch turned out to be a stronger fit because of the cohort and Spanish provision. The family had over weighted curriculum continuity for the younger child relative to her actual needs. Our American curriculum guide and British curriculum guide read together help families work through this question.

What the parents would do differently

The mother gave a precise list. She would have spent less time in early December on her nostalgia tour and more time on the schools. The week had been balanced but the school days had felt rushed. A second visit in late December, with the children, would have been calmer than packing everything into one week.

The father gave a different answer. He would have engaged a Spanish tutor for both children in Dubai for the six weeks before the move. Even basic conversational Spanish in week one would have shortened the younger daughter's adjustment. The family had assumed the school's Spanish programme would be the starting point. Starting at the airport rather than in week one would have been better.

Both parents agree they would have negotiated a fortnight of overlap with the previous Latin America head before the role started. The father had walked into the role on day one without any handover. The first month had been chaotic in a way that ate into family bandwidth. A handover would have been a small adjustment that the company would have agreed to.

The longer view

Sixteen months on, the family is settled. Both children speak conversational Spanish. The elder daughter has joined the school's debate team and is competing in English and Spanish. The younger daughter has become a competent gymnast. The mother runs two small projects in the city. The father has built his Latin America team out and is home most evenings. The family travel into the wider region regularly and the children have visited Oaxaca, Yucatan and Patagonia in their first year in Mexico. The family say the move turned out richer than they had expected. The mother says it has been the most personally meaningful posting of her marriage.
