saxon genitive, adjective or something else?

Hello,
the meaning of what I’d like to say is “the reality of education”. I give you a bit of context:"…in order to evaluate in what way it affects life, personal and institutional choices, and how it can be strictly linked to the reality of education and to child’s role"). I think I’ll go for “the reality of”, but could I say “education’s reality” or “education reality” or educational reality"? I could never understand very well the difference between them.

many thanks to who can help!

No, those don’t work-- go with your original: linked to the reality of education and to the child’s role.
