Thanks to Chris Dyson at Parklands, Leeds, who has provided this:
Subject leaders are now a prime target for inspectors and it’s not an easy position to be in, especially in a Primary school, but unfortunately (and I wish this wasn’t the case. as many are not even paid for the responsibility), they have to be very well prepared. This is a document which may help them. Good luck!

Hi Paul, reading twitter you .mentioned this morning that your school evaluaton diagnostic tool was freely available on your website. I can’t find it. Please could you send me a link. Thankyou
