Hi Anj
Updated info on the schools SEF can be found
hereI would tackle this in note form only to begin with, and you will need to discuss this with your SMT/leadership group and also your staff team.
Some parts are easier to write than others, for example outcomes you will need your profile data for the current year (just published) and also previous years to see where there are trends. If you haven't yet done this, this is a good place to start. It is important that you are realistic in your judgments, and also that you can justify them. For example if you say the quality of provision is 'good', why is it/ What makes it good? If you refer to some of the guidance documents on the page linked to above, there are some descriptions of what good, outstanding etc might look like. They are not specific to EYFS but give you that general idea.
Out of interest are there any members here who have recently completed or about to complete their school SEF so that you can share ideas about how you made your judgements?
