My dc were totally different at the end of reception.
Dd1 was writing long stories, half a side of A4 and more. Beginning to join up and very neat. Punctuation (Capital letters, full stops, question marks, exclamation marks, commas, some speech marks) well applied. Spellings pretty much all correct because she'd look up any that she didn't know. Not a lot of tricky vocabulary though because she didnt want the risk of getting a spelling wrong.
Dd2 wrote also long stories, probably longer. But she wrote in a stream of consciousness, which meant that there would well be no punctuation, and, although the spellings were usually phonetically correct, even simple spellings that she knew would often be wrong. But lots of tricky words Handwriting mostly joined up... sometimes across several words. 
Ds didn't write unless he had to. If forced he might manage. "love you love from ds" with objections... Capital letters a bit random (the letters that he thought were easier capital would be capitals, others lower case, so you'd get things like "lovE"or "cAmE") and b/d were sometimes reversed. Generally the letters would be properly formed though, and generally neat. He was being taught to do letters with a loop, ready for joining it up. Spelling, some phonetic, some just begiinning and ending letters, except those he knew where he would be consistantly correct.
