I know its a funny question but when does "writing" as far a primary school is concerned become less about the size and shape of the letters, or the use of punctuation and more about the quality of the ideas?
At the end of KS1, does it matter at all what a child writes as long as they know how to do all 26 letters and know when to use capital letters?
What about at the end of KS2? Does "writing" mean story composition by then?
