Phonics Assessment - Looking for the gaps in knowledge

When I am working with individual children or small groups of children who have phonic gaps for a variety of reasons e.g. glue ear, absence from school, dyslexia I have found that all the published phonic assessments don't pinpoint the exact phonemes that the children are struggling with. I have listed all the phonemes with examples of real words and non-words. I don't test the children on every phoneme but I select the areas that I think they may be struggling with to pinpoint where I need to target my intervention next.
