Children's attainment is measured in the Early Years Foundation Stage using "Development Matters."
In Year One, children participate in a Phonics Screening Check to test their phonic ability. Children are asked to read the sounds of forty written strings of letters. Collated results for the school are published nationally. Parents are also informed of their child's score and whether they reached the pass mark. If children do not reach the pass mark in Year One, they re-take the phonics test in Year Two.
Key stage 1/2
At the end of KS1 and KS2 children take SATs tests. The results are reported nationally as well as to parents. Information relating to these tests can be found in the link and videos below. Through these key stages, teachers regularly assess the children using informal, "low stakes" assessments to help inform their planning and teaching.
