Pupils and parents have been warned to have a “plan B” for getting to school for their exams during the rail strikes.
The major industrial action, which will see tens of thousands of rail workers walking out for most of this week, will clash with some A-level and GCSE exams set for Tuesday and Thursday.
The Department for Education has said exams are not expected to be rescheduled.
The Office of Qualifications and Examinations Regulation (Ofqual) and the Joint Council for Qualifications (JQC) – an association for major exam boards in the UK – said some contingency measures are in place for late arrivals.
Pepe Diiasio, head of Wales High School in Rotherham said people should have a “plan B in their back pocket” to get to school.
