Head Teacher meetings?

[natural]

Does anyone know how the headteacher meetings last for - specifically St Bernards? I was expecting it to be in the evening, but will be during lunch time. Because of the time just wondered how long I should expect this to be for (not mentioned on the letter) to determine whether I can take a long lunch or will have to book off the afternoon, and also to let the school know whether he will back.
Also any other information, eg content or what I should prepare, would be appreciated.

Is this a meeting with parents after an offer for a place has been received?

If memory serves me correctly - its about 10 minutes, not long. He just has a little chat with your child, asks a few questions, like 'what's your favourite tv programme', 'what books have you read', etc etc. Nothing too onerous, but quite a nice touch. Yes chad, this is after you've accepted a place there.
