Updated August 2026 · schools' own pages read 24 August 2026
International School teaches Cambridge Primary, Cambridge Lower Secondary to ages 5-19 in Vračar. Obrazovni sistem „Crnjanski“ teaches Serbian national programme, Cambridge Primary to ages 7-18 in Banovo Brdo, Žarkovo. The table below sets them side by side on everything either school publishes. Where a row says “not published”, that is the finding — it means the school does not put it anywhere public, and it is a good question to take to an interview.

What stands out about each
- International School: Uniform and textbooks are inside the fee; A distance-learning route at the same price; The steepest sibling discount in Belgrade: fourth child free.
- Crnjanski: Runs the IB Diploma, Cambridge and the Serbian national programme in one institution; Bilingual Serbian-English option at Cambridge Primary and Lower Secondary; Merit scholarships of up to 50%.
International School: The school states on its own site that it is IB World School no. 062142, authorised for the IB Diploma Programme. On 24 August 2026 that school number did not resolve on the IB's own register, and the school did not appear in the IB's programme finder for Serbia, which returned six schools. The school's Serbian-language fee page names only the Cambridge programme. We have not yet put this to the school. When we do, we will publish its answer here alongside the date we asked. Until then we describe the school as Cambridge, which is what its own fee page says, and we make no claim about why the register and the site differ.
Crnjanski: There is a separate International School Crnjanski in Jagodina, at crnjanski.rs. It is a different institution from the Belgrade Obrazovni sistem „Crnjanski“ at crnjanski.edu.rs.
What to ask both
Questions worth asking both schools, because neither publishes the answer:
- International School: The IB World School number 062142 claimed on the school's own site, which does not resolve on the IB register
- International School: Founding year
- International School: Cambridge centre number
- Crnjanski: Any published tuition figure
- Both: last year's actual leaver destinations and average results.
- Both: how many teachers in your child's year group were also there last year.
- Both: whether the bus covers the street you will live on.

Which is better, International School or Crnjanski?
Neither, in the abstract — and any source that answers that question is guessing about your child. The comparison that decides it is narrower: which one teaches the curriculum your child will finish in, has a place in the right year group, is reachable from where you will live, and can support your child's particular needs. This page is built to let you answer those four.
