David Holford has an update to his post about the British exam board requiring students to use “pbuh” after the name of Mohammed; he received word that this is not an official requirement:

“OCR will always put ‘peace be upon him’ after Muhammad in the form of an Arabic colophon as a mark of respect. However we do not expect candidates to do this.

A reference to this can be found on page 13 of the OCR GCSE Religious Studies Notes for Guidance.”
