The Rome IB landscape
Rome hosts an established international school market driven by diplomatic, UN-agency (FAO, IFAD, WFP) and corporate expat communities. International schools cluster in Rome's northwestern districts (Cassia, Olgiata) and central Rome. St Stephen's School (American Episcopal foundation, boarding option) is the long-established premier IB school. Marymount International School Rome is the long-established Catholic premier IB school. Ambrit Rome International and American Overseas School of Rome (AOSR) complete the credible IB tier. Cohort sizes are healthy with strong outcomes.
The 2026 top 5 IB schools in Rome
St Stephen's School
Rome's premier IB Diploma school with day and boarding options. American Episcopal foundation. Three-year IB average around 35 points. Strong faculty across STEM and humanities. Strong destinations to top US, UK and European universities. Default first choice for IB-committed Rome families.
Marymount International School Rome
Long-established Catholic premium school. IB Diploma alongside American high-school diploma. Three-year average around 34 points. Strong destinations across US, UK and European universities. Particularly attractive for Catholic-foundation families and others wanting strong IB programme in northern Rome.
Ambrit Rome International School
Anglo-American school with IB Diploma sixth-form. Strong cohort outcomes. Particularly attractive for British-curriculum families wanting IB optionality and strong cohort outcomes.
American Overseas School of Rome (AOSR)
Long-established American international school. Three pathways: US high-school diploma, AP and IB Diploma. Strong cohort outcomes. Strong destinations primarily to US universities. Particularly attractive for American-curriculum families wanting IB optionality.
Acorn House International School
Smaller international school with IB Diploma sixth-form. Strong family community. Particularly worth shortlisting for families seeking smaller cohort sizes and central Rome location.
What didn't make the list
Several Rome international schools offer IB Diploma but with smaller cohort sizes or insufficient three-year track records. Britannia International School and several smaller bilingual schools deliver IB Diploma at smaller scale. Worth investigating for families seeking smaller school environment.
IB vs. Italian Maturita
Italian Maturita is the local school-leaving qualification well-respected in Italian universities. For families committed to Italian universities (Bocconi, La Sapienza, Politecnico di Milano), Italian-curriculum schools are often optimal. For globally mobile families and those targeting US/UK universities, IB Diploma travels significantly better internationally. Most international school families in Rome target IB Diploma.
Italian university question
Italian universities (Bocconi, Sapienza, La Cattolica) accept IB Diploma directly. Bocconi University Milan in particular has strong reputation for accepting IB Diploma students into competitive economics and finance programmes. For families considering Italian university destinations, IB Diploma works well alongside the more traditional Maturita pathway.
