Staggered return in January for England's secondary schools
The return to school in January will be staggered in England's secondaries, with some starting online in rather than in class, the BBC has learned.
It will allow head teachers to set up a Covid testing scheme announced this week - but with exam-year pupils going back to start term as usual.
The National Education Union said making the announcement on the last day of the school term showed "panic".
School leaders will be expected to run and manage the testing regime.
Secondary school age children have among the highest infection rates but an ONS report suggests virus rates in schools reflect the levels in their local communities.
The government insists this is not an extension to the school holidays and primary schools will not be affected by the move.
