Turkish state schools are free and teach entirely in Turkish, which works well if your kids are young or you are settling in long-term. Most expat families with school-age kids choose an international school instead, for the English (or bilingual) curriculum and the easier transition.
Istanbul has the widest choice — British, American, German and IB-curriculum schools all operate there. Antalya and Izmir have fewer international options, so check availability in your specific district before committing to a neighborhood.
Annual tuition at international schools in Istanbul typically runs $8,000–20,000 per child depending on the school and grade level, plus a one-time enrollment fee that is often non-refundable. Turkish private (non-international) schools are usually cheaper, in the $3,000–8,000/year range. State school is free but budget for uniforms, books and transport regardless of which path you choose.
Most schools ask for your child’s previous school records (translated and often notarized), passport copies, and proof of your residence permit application or approval. Some international schools also require an entrance assessment or interview, particularly for older grades — ask early so you are not scrambling to schedule it after arrival.
