I've recently started my first headship, and 3 weeks in I'm struggling with whole school organisation. We are a large, 2 form entry primary school, and half the time, the left hand doesn't know what the right hand is doing. There are 3 shared office diaries which some use and some don't. TAs hardly ever check their email, and timetables for shared resources are not respected. There is no central overview of what's happening in school at any point in time. Weekly diary meetings on Monday morning have helped but take up a lot of time. I've looked at using an online calendar but it would be far too complicated for some of my support staff. Help!
