But parents (and teachers) should want to know how well their individual children can read printed words - and how well they can read compared to all children in the bigger picture - and I am hoping to persuade parents (and teachers where there is a lack of appreciation and misunderstanding of all the issues) to value the check and its broader findings which may require a different perspective.
The Department for Education guidance gives teachers discretion in discontinuing the check as appropriate - and any good teacher should be able to handle both the children undertaking the check, and feedback to parents, with good care and sensitivity. That's a measure of professionalism and people-skills.
The sad fact is that many of the teachers themselves do not understand the issues underpinning either the importance of phonics teaching or the importance of the Year One phonics check well enough and objectively enough - as can be seen by the varied responses to the check in the teaching profession itself.
The check is not adjusted for summer birthdays - but good teacher from Reception teaches summer birthday children effectively too - and of course teachers and parents can take this into account.
One big worry, however, is the idea that our very complex English alphabetic code is fully taught by the end of Year One - this is nonsense.
Even where children have been introduced to the code and many if not most of the children are reading well by the end of Year One, they still need to be taught or revisit the code for spelling purposes beyond Year One - and to embed the code knowledge and skills of blending for reading and segmenting for spelling as these can be 'lost' for at least some children.
Some children regarded as 'free readers' may default to a lot of multi-cueing guessing strategies so that this is their usual reading reflex - and some of these children at least will be the children who struggle more over time and yet no-one fully understands this.
Having said that, more and more people are beginning to consider that the weakest readers may be struggling with GCSEs not because of lack of intelligence but because of weak reading skills and not being able to access more challenging texts well enough - or not being very confident with spelling - which can give the appearance of lack of ability or which may rise to the 'dyslexia' label.
I would like to urge mumsnet parents to look at the bigger picture of 'literacy' and to see a value in the Year One phonics screening check which they may not have considered well enough.
And whether or not people consider that the government was right to promote systematic synthetic phonics practices, nevertheless the government itself needs to understand the practices within schools and their associated outcomes - and the government needs to be accountable for methods and materials promoted.
