Castelli International School sits high above Rome’s smog, in the healthy fresh air of the Alban hills, overlooking the historic city, surrounded by olive groves and vineyards. The first bilingual school in Italy founded in 1977 that offers a challenging  and inspiring educational programme  and a positive, nurturing environment where children flourish.


The school sees every child as an individual and recognises that children learn differently, and at different paces.  Our hands-on approach is clearly expressed in the Chinese proverb:
“When I hear, I forget. When I see, I remember. When I do, I understand.”


Mission Statement:

Our primary purpose is to develop the individual talents of our students through knowledge, skills and understanding while encouraging them to be inquisitive and resilient in dealing with change in order to confront the world of tomorrow with confidence and self-esteem .

Our students learn to relate the experience of the classroom to the realities of the world outside by focusing on a combination of academic, personal and international activities where they enjoy their learning, develop enquiring minds and work on the personal qualities that make them involved citizens of our world. By learning from different cultures they acquire a profound respect for the nationalities and cultures of others.
We believe in learning through structured purposeful inquiry.


Castelli International School’s bilingual programme spans five years of Elementary School and three years of Middle School.


  • International Primary Curriculum
  • International Middle Years Curriculum
  • Italian State Programme
  • Standard Achievement Tests

Bilingual Programme:

It is our belief that in today’s world students need to develop the ability to receive and transmit knowledge in more than one language. They thus acquire valuable cognitive skills and flexibility in reasoning. The bilingual programme is a comprehensive and balanced curriculum in which our International curriculum is integrated with the Italian programme. Students opting for the bilingual programme take the English exams and the Italian State exams. Students not fluent in Italian take Italian as a foreign language (IFL) until they can be fully integrated into the bilingual programme. Students not intending to take the Italian State exams may attend Italian classes (unless prior agreement for exemption is made), participate in class discussions and do the Italian homework to the best of his/her abilities after completing English homework assignments.

All core subjects are taught in English except for Italian and French, Chinese and Spanish (the latter two offered as extra-curricular activity ) are taught by mother tongue teachers. French is compulsory from the 5th grade onwards. French nationals, however, can opt for the (CNED) at cost, to facilitate entry into French public schools.

CIS alumni have successfully entered international schools worldwide, as well as the Italian High Schools (Licei Classico, Scientifico, Linguistico, Artistico) and Professional Institutes.

Admissions, Enrolment and Placement Procedures:

Enrolment is on a rolling basis. The Admissions Committee decides whether the prospective student can benefit and profit from the curriculum offered at CIS. To apply the admission forms must be filled out including school transcripts and teacher’s reference. Should a personal interview not be possible an interview form for parent and child will be sent via email.

Although there is some flexibility for individual needs and hence an overlap of ages may occur in any class, children shall have turned 6 years by the end of December of the year of entry.

Registration for first grade begins in December as limited space is rapidly filled.
