"Some of the principals are ready for a hybrid form - 50% in class and 50% remotely, with students changing every week, while others prefer the training to take place in two shifts," he added. However, the minister stressed that if the percentage of students infected with Covid-19 in a school rises sharply, it will be closed. 

"Our task is to have maximum face-to-face training, but without endangering the health of children and teachers," said Nikolay Denkov.
