The school was opened by the Turkish education ministry and belongs to it: the Turkish national curriculum, teaching in Turkish, the state e-Okul records system and the Turkish leaving certificate at the end. Every such school is named on the ministry's open list, each with its own institution number and a website in the state meb.k12.tr zone.
What the badge means for this school. This is a Turkish state school abroad, and that can be checked on the ministry's list. The entry is not a quality inspection: a school gets onto the list by belonging to the ministry, not by being assessed. The curriculum and the certificate are Turkish, and the school awards no international diploma. Whether it takes a child with no Turkish, and what it charges, are on its own website. The entry stands in the organisation's public register - anyone can check it.

What this means for this school. The programme is set by the Turkish ministry of national education, which also licenses the school and awards the certificate. The Turkish certificate is used for entry to Turkish universities; outside Turkey it has to be matched to the local one.
