More schools than ever were unable to fully open in England's latest teachers' strike, Department for Education (DfE) data suggests.
Teachers belonging to the National Education Union (NEU) took part in their fifth day of national strike action on Tuesday.
Members of four teaching unions have rejected a pay offer which ministers said was "fair and reasonable".
The NEU is considering three further days of strike action in the summer.
Based on the 16,400 schools which submitted attendance data:
- only 45.3% of schools were fully open on Tuesday
- 49.8% were open but restricting attendance
- 4.9% were closed.
The DfE data is an estimate of state-funded primary, secondary and special schools.
The worst-affected day in terms of school closures remains 1 February - the first day of the NEU's national strike action - when 9.3% of schools were estimated to have shut.
