and holistic

One of our major strengths is our well-rooted, hands-on educational philosophy. The natural environment of the school's campus and the multi-purpose facilities promote a holistic and collaborative approach to learning that fosters the students' ability to collaborate and think independently as well as critically.



Our international student body is well prepared to enter local Italian high schools as well as international high schools. Our students then proceed to national and international universities leading to successful career paths.
