The Directorate of Secondary and Higher Education also instructs the heads to reinforce the 'risky' buildings listed by RAJUK
The primary and mass education ministry in a notice on Sunday said that the pupils will remain at home in this period and join online classes to protect themselves from infection.
It asked the parents and the local authorities to ensure that the students stay at home.
The education ministry last week deferred the reopening of the secondary and higher secondary institutions to May 23 from Mar 30, a year after the shutdown began, amid a resurgence of infection.
The government cancelled the PEC tests for fifth graders, JSC tests for the eighth graders and annuals exams of other grades last year due to the pandemic while HSC results were published by averaging the scores of JSC and SSC tests.
