"In the event of a deterioration of the situation, and thus a transition to level four (system) of the PES, the measures should also apply to schools," spokeswoman of the Ministry of Education, Aneta Lednová, told ČTK. According to her, in the event of stricter measures, schools will primarily follow the instructions for the given degree, which they already have available. "As always, we will inform them about possible partial adjustments or timing in time, via data boxes," she said.
