Escuela Lomas Altas

A small bilingual primary school in Lomas de Chapultepec running the IB PYP from nursery through sixth grade, with families choosing it for the inquiry approach and intimate scale before moving children on to a secondary school of their choice.

Founded in 1976, the school stops at primary. Sixth-graders graduate fully bilingual in English and Spanish and feed into the city's main secondary schools, so families plan the next step from the moment they enrol. The PYP runs in roughly half-and-half English and Spanish immersion, organised around units of inquiry, with a teacher-to-student ratio that parents repeatedly describe as the reason they stayed.

The Lomas address puts it in the same corridor as Eton, Greengates feeder traffic, and the Lycée's Polanco campus, so commute is rarely the deciding factor. Catchment is mostly Mexican professional families with a thin layer of expats, and Spanish lands quickly even for children arriving without a word of it. Best fit for families who want a calm, language-rich primary and are happy to choose secondary later.

• Lomas Altas is a primary-only school: ages 1 to 12, IB PYP, founded 1976. Parents looking for a feeder into the IB Diploma route move children on for senior school.
• One r/MexicoCity parent who put their child through K-5 here described the 50/50 English-Spanish split as "wonderful" and credited the IB framework. The school recurs on Mexico City bilingual-school recommendation lists.
• Another local-parent comment classed Lomas Altas in the same bilingual primary tier as Sierra Nevada and Eton, with the American School and Greengates considered a notch above for fully international cohorts.
• One parent recounted physical bullying when their twins were 6, prompting a school move. A single account, but A real factor here alongside the otherwise positive primary-stage signal.
