I have a 6 year old in kindergarten, twin 9 in 4th grade and a 12 year in 7th grade. Thank you for any help :)
I am not an educator, although I am a parent of two bilingual children who have attended both Polish/International private schools in Poland I have also come into contact with many families who have lived in Poland for a period of 2-4 years. As a parent my concern would be the 12 year old it may be worthwhile paying for a private international school for him, or sending him to a state school/Gimnazjum which operates the IB program which is in Polish/English bilingual I am not familiar with Wroclaw in Warsaw this is a good school below contact them they may be able yo put you in with an equal in Wroclaw. Furthermore all state schools have catchment areas, so once you have established the best school you know the place you should be living. Good luck with it all.
