AOSR History Timeline
History of the American Overseas School of Rome (OSR) is Born!
October 16, 1947
As a product of five British and five American parents, having learned that the allied troops were being moved out of Rome and into Trieste, a nondenominational school combining the best of the UK and American systems was born. With help from the presiding American and British Ambassadors to Italy, this group of passionate parents found a location on Via Nomentana (Villa Torlonia) and officially opened the doors to the school for the first 60 students.
OSR Moves to Via Cassia
1951
In 1951, the school met the demands of rising enrollment by moving to its current location on Via Cassia. From there, OSR continued to grow. The United States government expressed its recognition of the school's quality educational program, and the importance of the mutual respect and collaboration generated by the exchange of ideas and experiences among members of the multinational student body and faculty, and therefore, gave a grant to the school. The new elementary school was constructed, additional high school classrooms completed, and the gymnasium built.

During the early 1960’s, with a focus on expanding curricular options, OSR was the first school in Rome to offer Advanced Placement courses to its High School students. Continuing this valuable academic  program to current day, our High School students have a choice of 18 different AP subjects.
In 1965, the Elementary School extension, and the levelling of the field were completed, giving our campus its current appearance. From above, the spacious and abundantly green design become evident. Our fields exemplify some of the cherished elements at our school, adding valuable outdoor space for our students to enjoy in sporting practice, leisurely games or simple outdoor enjoyment for anyone who comes on campus. An oasis in Rome.
