Tomorrow we launch our search for ATT’s first Chief Education Officer. This is not a conventional CEdO role. We want an exceptional educationalist who can think deeply, lead through others and help us build something special. Take a look tomorrow.

My first speaking session since leaving my role at Twinkl. Feels weird but strangely enjoyable to be preparing to speak at the next @LaSalleEd Complete Mathematics conference #Mathsconf41 using my old style PowerPoint template, rather than the Twinkl template. If you haven't got your ticket yet - you only have a week to go! Get your tickets here: completemaths.com/community/… Hoping to see plenty of my fellow maths ed colleagues for Friday night pre-conf drinks in Liverpool.

So today marks my last day working for @twinklresources. I have loved spending the last year (and a bit) working on my passion - to support maths educators everywhere in making maths teaching and learning as strong as it possibly can be. However, the best bit (as it so often is) was the wonderful people I have had the opportunity to work with. My fellow NELs Ashleigh Morris, @SamDenno_Twinkl, Nicola Romaine, Becky Dawson, @senresourceblog, Jon Park, @joncripwellmath, @karen_stretch, Kat Oakes, @ThePhonicsLead, @MrsPrimary_EYFS, @sarah_HDPriSci, Tracie Butterfill and my leaders Jo Jenkinson and @Twinkl_Leaders as well as others that I have been lucky enough to work with as part of my role like Nicola Allen, Rob Jennings, @MaryMyatt, @tomrocksmaths, Jennifer Almond, Cam Fermin, Nilam Patel, Cath Moore, Phil Chaffe and Matt Lucas. I have already lined up several interesting projects for the short term (after enjoying a short well-earned break) before I decide on my longer-term future. I would, of course, be happy to hear about any exciting opportunities my contacts might think I am suitable for.

I’m really annoyed at @Outlook @Microsoft I had my personal email hacked a few days ago. Very little help with it except to say they’ve upheld the suspension of my account. It’s my email! I’ve done nothing wrong. Just want it back as I’ve had it for nearly 20 years! Please RT

In announcing his reforms Andy Burnham said we should learn from Germany and the Netherlands as countries that have ed systems based on parity between academic and vocational education. But to what extent do the claims about those countries hold up? open.substack.com/pub/daniel…
