Meanwhile, the school's Klaipeda branch is yet to receive such permission.

"The minister has signed her consent for the International Ukrainian School to operate under of the Ukrainian education program," Dainoras Lukas, spokesman for Education Minister Jurgita Siugzdiniene, told BNS.

The permission will allow the school to receive the so-called pupil basket funding it has not received so far, but all other operating costs will have to be covered by the school itself, as it is not a state-run Ukrainian school. The Lithuanian ministry had contacted the Ukrainian Ministry of Education and Science and found out that it's a private school.

The school's Klaipeda branch is still getting its last documents in order.

The Ukrainian school has a total of 1165 pupils, including 756 in Vilnius and 409 in Klaipeda, the ministry said.

Both branches have around 115 staff, most of them Ukrainian teachers.

Some 18,500 school-age Ukrainians have arrived in Lithuania since the outbreak of the war in their country. According to the Education Ministry, about 12,000 Ukrainian children are registered with Lithuanian schools and kindergartens.
