Yes, in some ways, not immediately but over time we'll likely have more devolution which will allow more local control. Then they'll be digital exams within 10 years, if not less than that, they'll be more of a focus on skills for the future, so using AI as a tool responsibly, but also having critical thinking skills. They'll likely be more oracy skills in the curriculum, a mix of different testing types.
In terms of things like SEND, depending on what routes we go down, I can imagine some of what the children's commissioner wrote in her report happening, more SEN training within PGCEs and hopefully an expansion of the AP schools, both like PRUs and also SEN schools.
What specifically do you mean by one size fits all though? Are you talking about exams, various post-16 and 18 routes, curriculums, the types of schools - MATs etc. As it can mean a lot of different things, and some will likely change but not all.
