Good phonics teaching is beautiful to witness, though.
DD3 started school in September - April birthday, non-reader.
Her school uses Read, Write,inc.
Her first phonics assessment in October, showed that she was unable to sound some letters, was making an unpure attempt at others (e.g cuh) and could sound purely for a small number of letters.
At home, she was screwing up her face in concentration to recall the sound each letter represented, with big pauses between them.
Her November assessment showed most sounds were being produced purely, but a b-d mix up, and couldn't read digraphs yet.
At home, I had noticed that she was practicing sounding out words as she was drawing, etc.
Now, in January, she's sounding words out confidently, blending carefully, and starting to realise that if she knows a word is 'cat', she doesn't need to say /c/-/a/-/t/ - cat.
Her spelling is naturally progressing with her reading, because it's taught together. Letter formation is part of the phonics lesson.
My older DD who has SN is just starting to sound out words accurately - it's hit and miss (she's 8). At dinner she said 'I can spell really well, mum, look: d-r-d...fork' DD3 replied 'no it's not.... /f/ /or/ /k/'
