Because of the recent change of curriculum, it is not possible to make a direct comparison between a child's Key Stage 1 score (on the old levels) and their Key Stage 2 score (on the new scaled system). The Department for Education has devised a way of converting the scores on to the same scale, and then measured each child's progress in comparison with children nationally who achieved at a similar level at Key Stage 1. So, a child who made progress in line with the average for children of similar prior attainment would be awarded a progress score of 0. Otherwise a child will be awarded a minus or a plus score to indicate whether they achieved progress below or above the average, where the majority of children will fall within the range -5.0 to +5.0. These scores are then aggregated to give an overall average score for the school. Of course, within this average, there will be a wide range of different scores for individual children. The average progress scores for Willow Bank Junior School in 2019 are shown in the table below:
| Reading | -2.7 |
| Writing | -1.2 |
| Maths | -1.7 |
