Good question op, we do need to know roughly where other dc are so we can track rough progress but as pp said year 1 is very varying in ability @Mumofsend we don't know what send my dd has but she only got reading when we went back to basics with Peter and Jane books, and flash cards, then she was armed with the basics.
This one size fits all is not good, schools must be flexible and some brains will not get phonics.
I was lucky like Micheal mprppogo, one day all the letters made sense. If I had then had phonics forced on me it would have stymied my reading.
Some dc will not get or get on with phonics. My dd flew once she had the high frequency words, but she was hobbled without those building blocks.
Also breaking words down and learning about prefix and suffix have also helped her massively.
Now we have a mix of sounds and blocks and suffixes so she can quite easily spell words like occasionally.
Because we use trick for two collars and one sock to cover the cc and s. She knows the "tion sound, and that is the same with an s. Then finally she knows the suffix ally.
I urge any slow readers to try learning the basics first.
Op my advanced reader was still on the reading scheme year 1 over that summer to year two she was flying on chapter books.
Sen dd got to near the higher levels now year 3. Not quite a free reader but nearly there, we joined reading chest over lock down.
