This was not a desirable state of affairs, although it ranks fairly low on the scale of disruptions during a test. However, it is certainly not within the spirit of the guidance that Bucks CC provide to Heads.
An efficient school would probably arrange for there to be two members of staff in the room, or at least a second member of staff immediately outside the test room, in case of an incident.
The following quotes are from the Head's Manual:
Each test should be sat at a convenient time during the day as part of ordinary schoolwork, although under strict examination conditions. Quiet accommodation is essential, but it is left to the headteacher's discretion to make appropriate arrangements.
Please make every effort to prevent unnecessary disturbances during the tests e.g. music/PE lessons in nearby rooms: building/maintenance work outside etc.
Sign to request silence whilst tests in progress
The whispering was therefore not acceptable, and the admonitions to "hurry up" were certainly a long way from the "Protocol for School Testing" that Bucks provides for invigilating the tests. The only announcements specified in that protocol are as follows:
After 25 minutes say:
You have had 25 minutes, you have 25 minutes left
After 45 minutes say:
You have 5 minutes left
After 50 minutes say:
Stop now please and put your pencils down.
If there are other parents who are concerned about this, I suggest that you write to Admissions to point out these occurrences. Several people's individual accounts will be more effective than one, even if they differ - which they are bound to do, as each child will report back a different version of events. Hopefully Bucks CC may intervene to point out the error of it's ways to the school, and ask them to ensure that future testing is administered correctly.
The issues can be raised at an Appeal (not that you are going to need one of course!
), and might perhaps be considered to account for a mark or two going missing. It is important that they are reported now though, and you don't wait until the appeal, because such minor disturbances tend to sound like lame excuses at that stage.
