Hi, a very warm welcome to the site.
Pages 25+ of this level 2 CYPW handbook - link is to amazon.co.uk looks at unit SHC 2.3 and goes into detail about what equality, diversity, inclusion and discrimination are all about.
Deliberate and unintentional discrimination can occur in a setting through the resources available or not available, what people know and don't know about discrimination, what the visual environment looks like, stereotyping, the language that's used in the setting, talking about differences, celebrations and how everyone in the setting challenges discrimination and encourages change - working in a way that is inclusive.
Hope this helps a little, best wishes with your study xx
