Education of 11 years old boy

Dear blog members,
As per my search through the replies so far, I could not find a recent answer related with my need. I will be planning to move to Dubrovnik but first I need to find out a proper school for my kid (11 years old). Is there any international school?
I will appreciate ıf ı can get replies asap due to a time rush for a transfer,
Thank you in advance,
Regards,

No,  I don't think so. There are only international schools in Zagreb from what I've heard:
