Ah, @juggleit . That's enough time to deal with the phone call from an angry parent who's threatening to come down and sort you all out.
You need to determine the admissions policy for 2024-25 now. Do you need to hold a consultation on this? Best get a move on if you do. No, nobody's here who can explain to you what this means, just that if you haven't done it, the school is fucked. If you google the law on it, and work out where else you can find information, you might be able to swing it. Assuming you're aware of the governance - they can do this side, as not only is it admin, they're volunteers, so can't be expected to organise it.
How about the documentation that's legally required in the event of appeals? You'd better find that and get it all up and compliant, as appeals can come in at any time, not just after National Offer Day. I'm sure you can work out what day that is. You'll have to find out how to extract the data for the documentation from the previous year's figures, but nobody's here to tell you that you need to do that or how to do it.
It's also vital for when people appeal against their EHCPs, so you'd better get it done already as the consultations are already happening.
Hopefully you'll have a great time just pottering about with it, it's simple enough for you to take it on, after all.
Oh, and then there's all the bundle production, scheduling and minuting meetings, doing employment checks, helping the other admin staff, dealing with teaching staff, constant parents, a bit of parentpay, teachers2parents has started identifying your messages as spam, so you're going to have to rewrite the letters for each child and email them separately, we've run out of photocopier paper and the hot water tap is leaking so you need to find the warranty documentation and call the company whilst getting the caretaker to come down off the roof where he's repairing holes to turn the water supply off.
Best get your lesson planning done in the huge swathes of free time you hve from only doing Head's PA stuff.
Tl;dr - any teacher can teach.
