I think state schools vary wildly as everyone has said on here. I can say this from personal experience, as my DD is in reception and changed schools in April (state to state).
There is also the big factor of individual children learning at different paces. I can't really tell you what my DD's friends are doing tbh I can only tell you where she is at.
My DD is at ORT level 2 although her reading is more at ORT level 3. I think confidence has been an issue and the last school seems to be investing more time in her. At her last school her class teacher was very busy spending time with the large number of children who were behind in the minimum targets the schools had to achieve by the end of reception, so she was pretty much ignored and her confidence took a huge dip.
Also low level disruption was more tolerated and my DD really struggled to cope with this aspect, so she could never focus on a task as someone broke-scribbled-ripped her work. In her new school for whatever reason this is not happening.
In her current school she seems to be getting a lot more attention and she is becoming more confident and catching up with her reading. (By the way, we've always read with her at home but her confidence dip meant she suddenly begun to struggle and not want to read at all, ending up in tears very ooften).
Her writing is very good, she can write stories pretty much on her own with some spelling errors and she is very good on punctuation etc...I think this is because with writing she doesn't have to perform and she is more willing to have a go. Also her school is very keen on developing this skill and strength and she gets to write every day.
We get a few writing tasks to do home as well so that is clearly helping.
I can't answer your question on numeracy as nothing has come home and I am not sure what they are doing. I know she can add/subtract in decimals but we taught her that.
Hope this helped answer your question! As a last consideration I would say that comparing schools is every so difficult also because individual children need such different things to thrive and whilst some children thrive anywhere some need very specific things to happen. That's why it is never straightforward! But maybe this is going off your original post!!!
