DD's task involved writing a quiz (OCR) ...
I know that you completely didn't mean to and that it seems a fairly innocuous comment but this is an example of information about the NEAs being made 'available' on social media, easily. There will be students who are taking the OCR qualification who have yet to start their NEA. Indeed, some were planning to be taken off timetable over three or so days in Jan/Feb to sit the NEA in one go and be working on skills for it, right up until the end.
They would now know that the task is a quiz, they can now look up many solutions online and start memorising them - thus having an advantage over a student who didn't have this information, prior to starting.
Of course, by highlighting it, I am also complicit! But this was the argument that so many of us teachers told OFQUAL about the impossibility of keeping these NEAs a complete secret with 70,000 odd students/parents having access to the Web. It should never have got to this stage and OFQUAL should apologise for being responsible for a qualification that they were told wouldn't be enforceable.
