Admissions Admission runs all year: an enquiry via the website form, a tour, a meeting with the Principal in person or online, then the application documents: form, birth certificate or passport, Italian residence permit (non-EU citizens only), school reports for the last two years, any special assessments, vaccination record, nulla osta from a previous Italian school, teacher recommendations. Decisions are based on reports, recommendations, the language profile, an interview with the Principal, a class visit and the CAT4 cognitive abilities test. Applicants to grades 7-9 are assessed by EAL teachers; grades 10-13 require age-appropriate English, and an English entrance test covering four skills may be set. The school offers limited support for mild learning difficulties and sometimes admits on a trial basis. The high school states directly that it welcomes foreign and Italian students.

IBInternational Baccalaureate
A Swiss non-profit, working since 1968. Its programmes are among the most widely recognised school programmes in the world. Authorisation is granted stage by stage, so a school with the final stage does not necessarily run the younger ones; which stages this school holds is set out in the line below.
What the badge means for this school. The school is allowed to run this programme and to award its certificate. This is a confirmation of the programme, not a judgement on the school as a whole. The entry stands in the organisation's public register - anyone can check it. At this school: PYP (ages 3-12), MYP (ages 11-16), DP (ages 16-19). PYP is the primary stage, ages 3 to 12. It is not a set of subjects but a frame for the whole school: learning is built around lines of inquiry, and there are no exams at the end. MYP is the middle stage, ages 11 to 16. There are no exams here either; at the end an optional electronic assessment of pupils' work is possible. DP is the final stage, ages 16 to 19: six subjects plus a compulsory core of theory of knowledge, an extended essay and CAS. The diploma is accepted by universities all over the world, and in a number of countries it counts for admission on the same footing as the local leaving certificate.

Inspired Education Group is a private school group founded in 2013. The group gives different figures on its own pages - 125 schools on some, "more than 100" on others - and we quote both: choosing for a group which of its own numbers is correct is not something we do. Its schools are in Europe, Latin America, Africa, the Middle East and Southeast Asia, and some of them keep their own historic names, such as King's College in Madrid and Riga. The group's site is inspirededu.com.
What this means for this school. The network owns or operates the school. Its accreditation and programme authorisation the school obtains separately, in its own name.

Reviews
No reviews yet. The community rating counts towards the score once a school has five verified reviews - until then we do not show a zero, so as not to mislead.

A low score here means the school does not write about this, not that the school does not have it: a school with good security and a sparse site will score low. A school can fill in its profile, and the score will be counted again.
The score is counted from 8 of the 9 criteria.Only those with checkable data count: programmes and accreditations from official registers, the fee from a published price list. Where it says "scored on the median", the school has no data and the middle of the list is put in its place, so that a gap gives no advantage. Admissions, teaching staff and reviews come in as their data arrives.
