We have strong protocols on the return to school. I am really glad about the success of the policy to get all schools back; it is one of the Government’s unsung successes over recent weeks, and is working effectively. The guidelines set out very clearly when testing is appropriate. Testing is appropriate for people who have symptoms. Close contacts of people who have symptoms need to self-isolate and not get a test unless they have symptoms because getting a test would not allow them to leave self-isolation anyway because of the risk of false negatives. That is why the policy is as it is. We have given each school 10 or more tests so that they can easily use them in an emergency, and that has been warmly welcomed by most schools.
