Changes in standardised score over time
Posted: Sun Jan 26, 2025 9:00 am
71% of the 2023 KS1 cohort achieved a score of 5 or above in literacy. The last time we looked at this (based on the 2019 cohort), 77% of pupils achieved this standard. This gives an indication of the effect of the pandemic on the 2023 cohort.
Comparing the attainment of different groups in 2023, we see that 85% of Autumn born girls who were not disadvantaged achieved a score of 5 or above compared to 46% of Summer born disadvantaged boys.
Finally, we try to show how literacy brazil rcs data attainment gaps change from KS1 to KS4 for the groups of pupils we look at defined by gender, disadvantage (at the end of Key Stage 1) and term of birth.
The use of standardised scores gives us a way of using a score that has been made comparable across Key Stages.
Results are shown in the table below. By definition the mean score for each Key Stage is 0.
There are lots of numbers in this table but let’s pick out some of the key ones.
Firstly, the literacy attainment gap at KS4 for all disadvantaged pupils compared to all non-disadvantaged pupils in 2023 was 0.16 – (-0.44) = 0.6SD standard deviations. For reference, the standard deviation in GCSE English language was 2.13 points[5].
0.6SD at KS4 can be compared with the gaps at KS1 and KS2. These were 0.48SD and 0.44SD respectively. In other words, the attainment gap widened between KS2 and KS4.
