Hi
PC's stand for Performance Criteria (silly NVQ language), which are a list of statements you have to achieve in your practice when being observed by your assessor.
eg if your were undertaking a cooking activity with a group of children there would be a list of PC's relivant to that activity which said things like
~ ensure all children wash their hand before starting the cooking activity
etc
If you don't manage to cover all of your PC's for 'Element' during that assessor's observation, you are always able to plan another activity for the assessor to watch you do another time to cover the other ones. However, it is quicker to complete your NVQ if you don't have to have activities observed by your assessor more than once.
In your portfolio there should be lists of all your PC's for all your Units. Normally when your assessor plans an observation with your for their next visit they should talk through with you the PC's for that observation so you should know what you need to achieve. But I would always suggest reading through the PC's for the oservation your are going to be assessed for next, as much as possible, as it helps you to plan the activity well.
I hope this helps. Although I have never assessed for the new CCLD, I am a qualified NVQ assessor and assessed many many studants for the previous Early Years Care & Education NVQ's and they are all set out the same way, evan though the title has changed.
Good luck with your course
