Hi, it'll help if you have your setting's safeguarding and child protection policy and a colleague who can confirm the procedures for you.
For the first criteria you need to look at the wording in the case study to determine exactly what's being said (post the case study on this thread if you'd like more help)
and then in order to explain the role (what a person's position is in the setting) the responsibilities (what jobs they are expected to do in the setting - look in your setting's policy/job contract/staff handbook) and the actions that need to be taken (the procedures of a policy) you need to identify who's mentioned in the case study and use your handbook or the information from your setting.
For example you can read about the Key person role and responsibilities on various pages of
this EYE book on amazon. Use the index if you have a copy or search inside for
key person where you'll find some sample pages to help) alternatively your setting may have details about their key person system that you can use.
Key person on page 10, 22, 33 & 34 of the EYFS framework
The
benefits of parent partnerships can be read on page 94 - search inside for parent partnership
Hope this helps a little x
