Here is the current NHS advice:

 

Keep your child at home and away from other people if they have symptoms of COVID-19 AND they either:

• have a high temperature
• feel too poorly to come to school or do their normal activities

If your child has mild symptoms, such as a runny nose, sore throat or slight cough, but feels well enough, they can come to school.

 

If your child has tested positive

You are not required to give your child a COVID test but if they HAVE tested positive keep them at home and away from other people for four days, including the day of the test.
