A record 1.13 million children in England were out of school for Covid-19 related reasons towards the end of term, Government figures show.

Around 1,126,000 pupils missed class on Friday July 16, compared with 859,000 on Friday July 9, according to Department for Education (DfE) statistics.

The figures include 994,000 children self-isolating due to a possible contact with a Covid-19 case, 48,000 pupils with a confirmed case of coronavirus, and 33,300 with a suspected case.

A further 50,700 pupils were off as a result of school closures due to Covid-related reasons.

The DfE survey, which has been recording daily attendance in schools over the past year, closed on July 16 – when the number of children absent from class due to Covid-19 reached a record high since all students returned in March.

Current rules say that children have to self-isolate for 10 days if another pupil in their bubble – which can be an entire year group at secondary school – tests positive for coronavirus.

But Education Secretary Gavin Williamson has announced that the use of “bubbles” in schools in England will come to an end as the country eases lockdown restrictions.

Mr Williamson said it was up to individual schools and colleges whether they scrapped the bubble system ahead of the summer holidays, following the move to step four of the road map.

From August 16, children in England will only need to self-isolate if they have tested positive.

A study released last week found that daily testing of pupils who have been in contact with someone with Covid-19, rather than isolating whole groups, may be just as effective in controlling transmission in secondary schools.

Researchers at the University of Oxford estimated that daily Covid-19 testing in schools – as an alternative to the 10-day contact isolation policy – can reduce coronavirus-related school absences by 39%.

The DfE also released a regional breakdown of absences in state schools in England from June 10 to July 15. These have been adjusted to exclude those Year 11-13 students not expected to attend because they are off site.

The highest rate of Covid-related absence was more than one in four (26.5%) in the North East on July 15, while London had the lowest (9.6%).

The North East also had the highest staff absences on July 15, with 11.1% of teachers and school leaders – and 11% teaching assistants or other staff – absent for Covid-related reasons.

This compares with 6.6% of teachers and school leaders – and 6.4% teaching assistants or other staff – absent for Covid-reasons nationally on July 15.

This data shows very starkly that it has been an extremely challenging end to an extremely challenging school year

Geoff Barton, general secretary of the Association of School and College Leaders (ASCL), said: “This data shows very starkly that it has been an extremely challenging end to an extremely challenging school year.

“Two things must happen. One, the Government must put a much greater focus on putting an end to educational disruption in the autumn term and provide more support to schools and colleges. Two, it must also provide a much more ambitious and better funded recovery plan to address the learning loss experienced by many pupils during the pandemic.

“The plans it has announced so far are a long way short of what is needed by children and young people.”

Paul Whiteman, general secretary of school leaders’ union NAHT, said: “In the last few weeks of term, schools saw a huge drop in attendance. While much of this was due to pupils isolating, there was, unfortunately, a sharp rise in the number of confirmed and suspected Covid cases in schools too.

“It is clear that this level of disruption cannot continue next year. However, the Government needs to address the root cause of the problem, and not just the symptoms.

“Removing the requirement for close contacts to automatically self-isolate will no doubt reduce absence figures, but it is important the Government does more to actively reduce case numbers amongst children and transmission in schools.

“There is so much more the Government could be doing to give parents and school staff confidence ahead of the new school year and, ultimately, to make schools safer.”

Dr Mary Bousted, joint general secretary of the National Education Union (NEU), said: “The Government must learn from their sorry record this term.

“They must move now to announce what mitigations will be in place for September around mass testing, improvements to ventilation and testing of close contacts of children who have Covid.

“The absence of a Plan A, let alone a Plan B, is rightly alarming to school and college leaders and their staff.”

A DfE spokeswoman said: “Where children needed to isolate last term, schools were required to offer immediate access to high-quality remote education.

“As of step 4, schools no longer need to operate a bubble system, and from August 16 pupils will not need to self-isolate should they come into contact with a positive case, in line with the position for wider society.”
