Ukraine’s education ombudsman has advised schoolteachers to act as if they only understand Ukrainian when speaking with students. Kiev mandates the use of Ukrainian in most aspects of public life, despite a significant portion of the population speaking Russian as their native tongue.

In an interview on Monday, Nadezhda Lishchik said her office had received complaints from school administrators about students who refused to speak Ukrainian during breaks. While teachers are required to speak Ukrainian at all times, students are allowed to use any language outside of the classroom.

”My advice was: ‘You are not obliged to know a foreign language, unless you teach one, like English or German. You have full right to say you don’t understand and insist on being addressed in the same language you use during classes.’ You can influence students in a gentle way,” Lishchik said.
