The ministry will provide information as necessary, in cooperation with the national civil protection authority, Divjak told reporters, dismissing a question about a possible threat from Italy.
We are sending headmasters everything we have planned, primarily instructions concerning hygiene, assembly and travel, she added.
She said a UNESCO conference on how coronavirus was affecting education would be held tomorrow and that certain conclusions would be made.
For Thursday, Dvjak convened a ministerial conference of the EU's 27 member states at which the EU's response to the impact of the virus on education was expected.
It's very important to see the practice in the member states and we expect conclusions which would be universal for all, she said, adding that Croatia was prepared to coordinate all activities and that this was why the conference was convened.
Headmasters must see to hygiene measures, for which the ministry is giving them money, Divjak said. "I'm sure the money is there, but it's necessary to see to it that all that is necessary is procured and that the money is given to schools in time."
