Coronavirus: Will the start of the new school term be delayed?
Yesterday the NEU teaching union urged the government to move teaching online for the first week of next term to give schools enough time to train staff in administering Covid-19 tests.
The call came after the DfE announced that every secondary school in England, as well as special schools and alternative provision, will have access to rapid coronavirus tests from next month "to help keep staff and students as safe as possible and in education".
A DfE spokesperson said: “Children’s education is a national priority and this government has acted in the interest of children since the start of the pandemic.
“Schools, colleges and early years settings across the country have worked tremendously hard to put protective measures in place that are helping reduce the risk of the virus being transmitted.”
