hi, are you a primary SENCo or secondary? I am a secondary SENCo – but I think either way it sounds like you are really focused in your plan. I am wondering if you are already familiar with the Maximising the Impact of TAs work? as that could be a useful link for you – https://educationendowmentfoundation.org.uk/projects-and-evaluation/projects/maximising-the-impact-of-teaching-assistants . The teachers really need upskilling in strategies for Quality Teaching for neurodiversity by the sound of it. I have some resource I could share with you. Not sure if there is a way of reaching out in a PM here?
