The International Baccalaureate is today informing schools outside the UK about whether their exams will go ahead.
But schools within the UK will not learn whether their exams will be cancelled, with grades based on teacher assessment instead, until 22 February at the earliest.

International Baccalaureate 2021: Exams in some countries
Outside the UK, IB schools will get more definite news about how their students will be assessed this year from today.
The International Baccalaureate has said it will offer a "dual route" for its grading process this year, with schools in some areas taking exams while others award grades through teacher assessment.
Earlier this month, following a January survey of 3,000 schools in more than 152 countries, the IB said it was working with schools to "determine which of the two pathways is best for their region: written examinations, where they can be administered safely, or an alternative route using a combination of internal assessment coursework and teacher-predicted grades where they can’t."
