Clearly a politically and humanly battered country at the moment (2024). It seems that Ukrainian is the only official language though a substantial minority of the population, probably particularly in the Crimea and areas invaded by the Russian Federation speak Russian as their first language. There are number of minority languages but each used in only very small in numbers compared with those two languages. As of summer 2024 we have good translations of the CORE-OM and shortened adult forms for both languages.
Do contact me if you want something added here about the use of CORE instruments in Ukraine or in the Ukrainian diaspora.
