Exclusions data for the full 2021/22 academic year will be published later this week, just as the 2022/23 academic year is winding down.
There is a lag in the collection of data: exclusions for the summer term 2021/22 were collected in the Spring School Census. This is to allow time for appeals against exclusions to be heard. Although the Census relates to a specific date in January, schools have a longer window to submit the data.
Then statisticians take a few months to clean the data and assemble the exclusions statistics.
Data for previous years has tended to show that pupils with special educational needs (SEN) are disproportionately more likely to be permanently excluded although, as this blog shows, the picture is more nuanced than that.
