Hi Dick, you said:
A child who can read all 40 items on the "Phonics Reading Check" does not require any additional instruction in reading, per se.
I'm afraid I cannot entirely agree with you regarding your comment above, although you may well be right that children reading all 40 items are well on their way to being competent readers for life.
I know of a Reception teacher (teacher of four to five year olds) who routinely uses the Year One Phonics Screening Check (for the five to six year olds) with her Reception class.
Two-thirds of her class reach or exceed the 32 out of 40 benchmark for the check.
It could be that these Reception children are so well-taught with regard to the alphabetic code and blending skill that they, too, arguably, may not need further phonics teaching for reading.
Or it could be that the check itself is not that challenging considering the complexities of the English alphabetic code.
Or it could be both.
Or it could be that without a more comprehensive knowledge of the letter/s-sound correspondences of the English alphabetic code that too many of the children will stall out with more challenging words or will resort to 'guessing' the words which include code they don't know - especially within words that are not in their existing vocabularies - or 'skipping' the words entirely when reading silently when they don't know the words already.
In any event, teachers should be teaching the alphabetic code not only for reading but also for spelling. Some people think, me included, that the value of teaching phonics for spelling goes on for much longer even when children are to all intents and purposes now proficient readers. My version of 'phonics for spelling' includes an emphasis on 'spelling word banks' where words with the same letter/s-sound correspondences are glued together with the design of resources and activities.
