"The phonics screening check is a short, simple assessment to make sure that all pupils have learned phonic decoding to an appropriate standard by the age of 6. All year 1 pupils in maintained schools, academies and free schools must complete the check.
The phonics check will help teachers identify the children who need extra help so they can receive the support they need to improve their reading skills. These children will then be able to retake the check in year 2.
The check comprises a list of 40 words and non-words which the child will read one-to-one with a teacher."
