Behind the scenes, plenty of work has been done to ensure pupils stay safe as they return to school.
High on the list of school priorities is sticking to a strict Government plan if a child or staff member tests positive for coronavirus.
This will usually involve sending some children home to self-isolate because they have been in close proximity to the infected person.
But what are the rules about which children are sent home, and what should other members of the household do?
The first thing that happens when a school is informed that a pupil or staff member has tested positive is that the local health protection team steps in.
Their first job is to identify who has been in close contact with the infected person.
This includes "direct close contacts", "proximity contacts", and those the person has travelled in a small vehicle with.
"Direct close contacts" means face-to-face contact within one metre over any length of time, including conversations, skin contact, or being coughed on.
"Proximity contacts" means extended close contact of more than 15 minutes within one or two metres.
Once that has been done, the local health protection team will advise the school to get in touch with those people who have been in contact with the infected person, and they will be told to self-isolate for 14 days.
Other members of the same household do not need to self-isolate if a child has been sent home because they were in contact with the infected person.
The only reason why others in the same household would need to self-isolate is if the child who was sent home develops symptoms.
If that happens, the normal rules apply, and the child would need to have a test.
If the test is negative, they should still remain in isolation for the rest of their 14-day period.
However, if the test is positive, they will need to self-isolate from 10 days since the symptoms started.
The rest of the household would also need to self-isolate for at least 14 days from the onset of the child's symptoms.
