Study / Are English only speaking students accepted into public Wroclaw school? Spanish ones too? [12]

[Moved from]: Migrating to Wroclaw - public schools in English or Spanish for children?

I will migrate to Wroclaw with my family, I have two children (7 & 5), they only speak spanish, so I was looking for
a international school for them but they are very expensive.
I wonder if in Wroclaw there are public school in english or spanish?. or
may be a less expensive school.
