Level 4 is not an average, MiceElf; it is an expectation for pupils leaving primary school. Having said that it was not set in a very scientific way and wasn't norm referenced. Here is Level 4 for writing.
"Level 4
Pupils' writing in a range of forms is lively and thoughtful. Ideas are often sustained and developed in interesting ways and organised appropriately for the purpose of the reader. Vocabulary choices are often adventurous and words are used for effect. Pupils are beginning to use grammatically complex sentences, extending meaning. Spelling, including that of polysyllabic words that conform to regular patterns, is generally accurate. Full stops, capital letters and question marks are used correctly, and pupils are beginning to use punctuation within the sentence. Handwriting style is fluent, joined and legible."
As you can see it is not just a minimum standard and would challenge quite a lot of writers. If you look at the higher levels, you will see lots about purpose and audience. I think it was about 85% of pupils who got Level 4 this year (haven't got the data to hand.) Girls have always outperformed boys by quite a lot, but the gap closed this year. The Level 5s were also much higher than last year.
