These pupils would have entered the school system under the previous SEN code of practice, turning 4 in 2012/13, and would have been age 6 (Year 2) in 2014/15 when the new one was introduced.
To make the comparison with australia rcs data the 2013/14 Year 11 cohort a bit easier, I change the bars in the previous chart into a line.
Then I add another line for the 2023/24 Year 11 cohort.
We see that the lines for the two cohorts are very similar up to age 9, at which point they begin to diverge. There is a noticeable increase in the EHCP rate between age 9 and 10 for the 2024 cohort. Between those two years, the rate increased by 0.7 percentage points. It then increased by 0.4 percentage points each year from 10 to 14, a much sharper increase than for the 2014 cohort.
By age 15, 5.6% of the Year 11 cohort had an EHC plan.
How many pupils in Year 7 have an EHC plan?
Finally, let’s look at a different cohort: Year 7 in 2023/24.
These pupils would have been aged 2 in 2014/15 when the new SEN code of practice was introduced.
At age 4, the percentage of pupils with an EHC plan was slightly higher than the previous cohort we looked at.
