Got my first graded inspection within the next 2 weeks (4 possible dates).
I am still working on my SEF, it's awful and I am struggling.

What will they ask to see? Got registers, permissions, contracts, child record forms, RAs, anything else?

learning journies or other evidence of how the children are progressing , possibly evac procedure and fire drills , youve probably got all those. What they want to see are happy well cared for children , get together all your photos of the things you do and either put them out for her to flick through or have a slide show going on the laptop. blow your own trumpet - they cant possibly see everything in a couple of hours so use your sef to tell them about all the great things you do and how they have helped the children to settle / progress etc.
Good Luck x
