Students who are unable to take their exams today because of the snow will have to wait until the summer for the next chance to sit them, according to advice given to schools by the Joint Council for Qualifications (JCQ).
Awarding bodies have procedures in place to deal with disruption to exams caused by the snow and ice that is affecting large parts of the country.
These well-rehearsed processes ensure students are not disadvantaged.
In the majority of case exams will go ahead as usual, but where conditions are so severe that schools are closed or students are unable to make it to their exams, alternative arrangements are available.
This may include holding the exam at an alternative venue or students taking it later in the year.
In extreme cases, special consideration may be applied for.
