Only the 10th and 12th graders have to attend classes in person every day while other secondary school and college students may visit their classrooms once a week when their educational institutions reopen during the pandemic. The government will decide when to reopen the schools after analysing the situation and consulting with the National Technical Advisory Committee on Covid-19, Education Minister Dipu Moni told parliament yesterday. The Directorate of Secondary and Higher Education (DSHE) on Friday instructed all schools and colleges to complete their reopening preparations by February 4. She said the government will bring students of classes 10 and 12 back to schools and colleges for the sake of their studies ahead of the SSC and HSC exams.
