In Brief
A well-established Catholic school with 60 years in Naucalpan, strong facilities and a close-knit community. Right for Catholic families who are comfortable with gender-separated education and a Mexican-dominant social environment. Not the right fit if you need a diverse international peer group or are non-religious.
Irish Institute Mexico has been operating since 1966 and recently marked its 60th anniversary. Run by the Legionaries of Christ, it sits on Fuente de Leones in Lomas de Tecamachalco in Naucalpan - the same general area as Greengates, though a different kind of school entirely. Boys and girls are educated on separate campuses from Primary onwards; preschool is co-ed. Around 988 students attend across the two campuses. The 98% Mexican student body means this is not an international school in the conventional sense, but for Catholic families looking for a values-led bilingual education with a stable, multigenerational community, it is one of the more established options in Mexico City.
The school offers Cambridge certifications and College Board exams, and runs a dual diploma programme with Providence Country Day School in Rhode Island - a useful pathway for students targeting US university admission. Class sizes average 21, with a maximum of 25, and teaching assistants are present throughout. Facilities are well-developed: chapel, STEAM labs, soccer fields, swimming pool, basketball courts, cafeteria, library, makerspace (boys) and a psychomotricity room. School hours run 7:15am to 2:30pm with a uniform requirement. The bus service is operational and the Naucalpan location is manageable from Polanco or Lomas but a trek from the south or east of the city.
Irish is an Apple Distinguished School and consistently places 99% of graduates into further education, with scholarships available for graduates through Universidad Anáhuac. Fees are not published; contact the admissions team directly. The gender-separated structure is the defining consideration - families who want co-educational secondary schooling should look elsewhere. For those aligned with the Legionaries of Christ ethos and comfortable with the structure, Irish has a loyal community with families who have sent multiple generations through the school.

Student Body
Around 988 students across boys and girls campuses, with preschool co-ed. The student body is 98% Mexican from just 2 nationalities - one of the most locally concentrated schools in this guide. Families come from across Mexico City but the community has a strong multigenerational character, with many parents who attended the school themselves.
Average class size is 21, maximum 25, with teaching assistants throughout. The gender-separated structure from Primary means boys and girls have separate academic and social environments from around age 6. Families should visit both campuses if considering the school.
