Students have become “anxious” about their grades after it was announced yesterday that A-level and GCSE summer exams are cancelled.

The news came after the announcement that schools across Wales would be closing from tomorrow, Friday, for students except those who are the children of key workers.

However, schools are now appealing for further clarification about how grades will be decided if not through exams.

In her statement, Ms Williams went on to say that students will be awarded “a fair grade to recognise their work, drawing on the range of information that is available”, but did not provide any further information.

Dafydd Jones, headteacher at Ysgol Bro Hyddgen in Machynlleth, said: “I think, the way things are, it’s the right decision to cancel exams because I suspect we are going to be off work for longer than four weeks.

“But we need clarification from the examination board how graders are going to be awarded.

“In his interview, Boris Johnson said it would be based on expected grades or something similar. There needs to be the same method of collecting these grades for everyone, so it’s a universal formula through all schools.”

On the feeling amongst students, Mr Jones said: “There’s an anxious, even disappointed, feeling because a lot of them have worked very hard for almost two weeks.

“Some of them have been revising for weeks, months even, and then to find out that there’s no need.

“All the work they’ve put in feels a bit void.”
