Reading these posts I was thinking on how useful this website has been for me as a new AHT. People are always so generous in giving useful advice.One thing that has made a difference to my work was the link to a website about using data and school evaluation, Ofsted etc. It was at www.mikebostock.wordpress.com and I gone back to it several times because my role is for pupil attainment and monitoring. It is full of ideas and has very sensible advice. You can work out what you are doing wrong from it. We have changed our approach over this term to how we are using exam data and target setting.
