Izzi Science for Kids (officially the private secondary school Nauka za deca) is a private full-day school in Sofia with a science focus, from a day-care centre for 2-year-olds to Grade 12. The school teaches bilingually, in Bulgarian and English: the Bulgarian state curriculum with extra hours of Bulgarian and mathematics is combined with Cambridge programmes. The Izzi Start day-care centre (ages 2-4) follows Cambridge Early Years, the Izzi PUK preschool groups (ages 5-6) follow the Bulgarian curriculum one year ahead and Cambridge, and the Izzi Science primary and lower secondary school (Grades 1-7) follows the bilingual STREAM programme and Cambridge Primary. The SMART Science high school (Grades 8-12) combines the Bulgarian curriculum with Cambridge Upper Secondary (IGCSE) and Cambridge Advanced (A Level in Grades 11-12), with Cambridge courses taught in English; graduates receive the Bulgarian diploma and the Cambridge International Diploma. Grades 11-12 offer four profiles: natural sciences, social sciences, entrepreneurship, and mathematics and computer science. The school reports more than 500 students and is part of the state funding system: some places in the preschool group and Grades 1 and 8 are free.

CambridgeCambridge International Education
Part of the University of Cambridge. It allows a school to teach the Cambridge programmes and to enter pupils for the exams. There are four stages and they are authorised separately: primary, lower secondary, IGCSE and A Level. If the stages are known they are named in the line below; if that line is missing, the school does not publish them, and the Cambridge registry does not show stages either - it gives only the name of the centre, the country and whether private candidates are accepted. Cambridge calls what it does registration rather than accreditation, and the network holds about ten thousand schools.
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: Primary (ages 5-11), IGCSE (ages 14-16), A-Level (ages 16-18). Primary is the primary stage, ages 5 to 11: English, mathematics and science to Cambridge syllabuses. At the end of the stage a school may run the optional Checkpoint test, which is marked in Cambridge. IGCSE means exams at around Year 10 or 11, the British counterpart of a lower secondary leaving certificate. A-Level is the senior years, and their results are what British and many other universities admit on.
Register to check for yourself, and the full guide →National programme
The state school programme of the country the school stands in: it is set by that country's ministry of education, which also licenses the school and awards the leaving certificate. That certificate is used for entry to local universities, and abroad it is matched to the local one.
What this means for this school. This entry does not count towards the score, and that is deliberate. Every lawful school in a country works to the national programme, so on its own it tells one school apart from no other - unlike the French, German or Russian programmes, which are carried abroad and confirmed by the register of their organisation. We show it because a parent needs to know what programme their child is taught and what certificate the child will get. Counting it would lift the whole ranking at once and still tell nobody apart.

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 7 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.
