What it is like here
Warsaw's international schools charge roughly what a mid-tier German school does and sit in one of the safer countries in Europe, so the schooling side of this works. What we could not establish is the part that decides whether it is possible at all: whether a parent can accompany a child here on a route of their own. Until that is confirmed the score below is missing its hardest ingredient, and the page says so rather than filling the gap in.
How the process works
Apply to the school
Warsaw's established international schools admit by assessment and interview; places in popular year groups go early.
Establish how the family will be resident
This is the open question, not a formality. Confirm with the Office for Foreigners before committing to a school place.
