Hi
The best way to approach this would be to obtain copies of policies for your setting.
Find the points you have listed in the policies and list the key points releating to the areas you have listed. If you are working to EYFS say which sections of the EYFS guidance your policies fit into.
European legislation - our awarding body said there aren't any, so ignore this - but best to check with your assessor.
Confidentiality, data protection, sharing of information, reporting, recording - If you have already completed 203 (child observations) 202 (Safeguarding - child protection) you should already have this evidence in these units - all you need to do is x-reference.
Barriers: conflict, differences of opinion and how you have dealt with these issues. If you haven't say what you would do.
Hope this helps
