Hiya and welcome to Silkysteps.
Have you had a look through the Safeguarding children page of the dcsf's website -
Safeguarding children and social care other help is to speak locally to your own group's lead, EY' department advisor & assessor/tutor for ideas on where to gather information, policy & procedures from.
Other links that may help are
Child protection from NSPCC
Knowing the names of your own Setting's policies, what the procedures are and what documents / forms are used for data collection will help as will knowing which other agencies/organisations & professionals have links with your group.
Best wishes with it all and enjoy the site
Ruth
