ah I do love it when a #manynumbereduser comes onto a thread, spouts bollocks about "their experience" and is put in their place by established non numbered posters....
nobody has "put me in my place" at all what weirdly bizarre thing to say.
And it is clear that i am the person here with the most experience of running exams, by a very long chalk.
For example, there are people here claiming scribes have a room each and don't need to be invigilated! Maybe in private schools, with the parents paying for the privilege, or in a few selective schools, or schools with abnormally vast resources or low levels of SEN
otherwise no, sorry.
The OP is saying the heat was the issue, yes maybe there were complaints about the heat and candidates reacting badly to it, maybe the room temperature was being monitored and causing concern.
Invigilators whispering about conditions in the exam room and monitoring and adjusting it - absolutely not a cause for complaint.
I'm sorry your daughter felt distracted, but that is up to her to manage, it isn't possible to provide a completely silent environment ever, and some situations will require more noise than others. Sorry, but she is not A* material, if a whispered discussion about the temperature in the room is going to make her lose marks. Unless she has some form of persistent dis tractability, in which case she should have applied for extra time
Given the heat , and the content of the conversation, it is likely that there were others in the same room who will have wanted this discussed more, and more adjustments tried, and the invigilators to have made more noise about it.
What difference does it make that the exam was in a class room, rather than a hall? Most schools have only one hall, or two at most, and will be using many classrooms for exams, this is normal practice.
