The Mexico City IB landscape
Mexico City's international school market serves a deep US, European and Asian expat community plus a substantial Mexican professional family base seeking international curricula. American School Foundation (ASF) is the long-established premier American school offering AP and IB Diploma. Greengates School is the premium British-foundation school with IB Diploma. Edron Academy, Eton School and Westhill International round out the IB tier. Schools concentrate in Lomas, Polanco, Bosques and Santa Fe.
The 2026 top 5 IB schools in Mexico City
American School Foundation (ASF)
Mexico City's premier American international school. Three pathways: US high-school diploma, AP and IB Diploma. Three-year IB average around 34-35 points. Strong faculty across STEM and humanities. Strong destinations to top US universities. Default first choice for IB-committed Mexico City families with American or Mexican-American backgrounds.
Greengates School
Premier British-foundation school. IB Diploma sixth-form alongside IGCSE. Three-year IB average around 34 points. Strong destinations across UK and US universities. Particularly attractive for British-curriculum families wanting IB optionality at sixth-form.
Edron Academy (The Edron Academy)
Full IB Continuum school. Strong cohort outcomes. Beautiful campus. Particularly attractive for families wanting IB-only pathway with no curriculum switch through to sixth-form.
Eton School
Bilingual school with IB Diploma alongside Mexican national curriculum. Strong cohort outcomes. Particularly attractive for Mexican-national families wanting IB optionality with Mexican-curriculum integration.
Westhill Institute
Bilingual school with IB Diploma stream alongside Mexican national curriculum. Modest fees relative to ASF or Greengates. Particularly worth considering for Mexican-national families seeking IB at sub-premium fees.
What didn't make the list
Several Mexico City schools offer IB Diploma but with smaller cohort sizes or insufficient three-year track records. Colegio Aleman Alexander von Humboldt offers strong German pathway with IB optionality but smaller IB cohort. Lycee Franco-Mexicain offers French Bac with IB optionality. Both worth investigating for nationality-specific pathways.
IB vs. American AP in Mexico City
ASF uniquely offers all three pathways (US diploma, AP and IB) at scale. For US-bound students, AP is often the more direct pathway; for globally mobile students, IB Diploma travels universally. Greengates and Edron are committed to IB Diploma as primary sixth-form pathway.
Mexican university question
Mexican university entry (UNAM, ITAM, Tec de Monterrey) traditionally requires CENEVAL exam and Mexican high school diploma; IB Diploma is increasingly recognised by Mexican universities but the CENEVAL pathway remains dominant. Most Mexican universities accept IB Diploma directly; some require additional CENEVAL preparation. For families committed to Mexican universities, IB plus CENEVAL preparation is optimal.
