The retention rate is the proportion of students who are retained to the end of the ‘core aim’ (or main learning aim) of their study programme at a school or college.
Retention data for 2021/22 will be published on 30 March 2023 in the next update and will be available at: https://www.gov.uk/government/statistics/announcements/a-level-and-other-16-to-18-results-2022-revised--2.
Since 2010, the department has put in place a range of policies that have significantly reduced the quantity of young people designated as ‘not in education, employment or training’ (NEET). The proportion of 16 to 24-year-olds NEET in 2022 was 12.3%, which is down 3.2 percentage points since 2010.
