Bringing in the AC did mean they needed to push a bit more into the curriculum at Pre-P level and push along all other levels. That was not easy on anyone, regardless of when their birthday was!
I'm assuming the list you provided are end of year outcomes expectations. They all look pretty reasonable for a child 5y 4m old - however I know when dealing with curriculum documents there can be some interpretation of what "achievement" actually looks like. Then there is the distinction between curriculum you need to cover and what you expect a child to know and do.
"Use comprehension strategies to understand and discuss texts listened to, viewed or read independently"
Looking at this example, what this means is that after you have read a book to a child they can tell you one or 2 details/main ideas and/or answer some questions about it (eg. Who was the story about?)
They're all in "curriculum-speak" making them sound more complex than what they are.
