AOSR is made up of 597 students from around the world. We pride ourselves on maintaining a ratio of one-third of the student body as American, one-third as Italian, and one-third of other nationalities.

AOSR is truly an American international school, with a third American, a third Italian and a third international families. We offer a diverse community with 50 nationalities represented in our student body.  

80% of our teachers hold advanced degrees and 83% are native English speakers. Our faculty members have taught at international schools in over 43 countries around the world.

93% of our IBDP and AP students succeed in the exams and receive an International Baccalaureate Diploma or Advanced Placement Diploma. 

89% of high school students are enrolled in either an Advanced Placement or IB course.  Since most AP and IB students are in Grades 11 and 12, this number is close to 100% at the upper secondary level.

In 2023, our students secured acceptances from esteemed institutions such as Yale University, Paris Business School, King's College London, University of Sydney, and many others.
