I agree with hookie. It very much depends on the inspector. Sorry.
I got outstanding at my recent inspection. I honestly put it down to having an inspector that 'got' me, and liked the way I worked. The inspector at my last inspection didn't.
This time, the inspector couldn't praise relationship with parents highly enough. The previous one rated me 'satisfactory' in that area simply because I didn't use 'All About Me' forms when children started with me - my practice hadn't changed one bit between inspections.
As someone on here once said - think it was someone called Tiggy or similar - it's one inspector's opinion on one day.
All that said:
Make sure you know safeguarding inside out - and DON'T forget to include no mobile phones in your policy.
Give parents a questionnaire to complete; parent feedback really is valued.
Make sure you have up to date written profiles - whatever is said about there being no need for this, they like to see them.
Try to relax (I know!) and talk to the children as naturally as possible - they're looking at your interactions,
I didn't complete my SEF. If you don't, be prepared - the inspector will talk you through any sections you haven't completed!
If I think of anything to add (it's late) I'll come back
