Friday marks the last day at school for most children across the UK until further notice, in response to the escalating coronavirus outbreak.
Schools in England, Scotland and Wales will close on Friday to everyone except vulnerable children, and those with a parent identified as a key worker.
Schools in Northern Ireland will shut from Monday 23 March.
A-level and GCSE exams, and primary school SATs – usually taken in May and June – have been cancelled.
Most local governments have indicated schools may not reopen properly until the end of the summer.
The government has published a list of key workers whose children will be cared for at school to enable their parents to continue with work considered to be essential during the pandemic.
The list has been separated into eight categories, including frontline health workers and social care staff, nursery and teaching staff and those involved in food production and delivery.
It also includes the police, those in key public services – such as the running of the justice system and public broadcast – transport workers and critical staff in financial services and utilities.
