Question to the Department for Education:

To ask Her Majesty's Government how many (1) vulnerable, and (2) disadvantaged, pupils are not currently attending school.

The closest matching available data on the attendance of vulnerable children in educational establishments since 23 March was published on Tuesday 16 June at the following link and covers data up to Thursday 11 June:
https://www.gov.uk/government/publications/coronavirus-covid-19-attendance-in-education-and-early-years-settings.

The data is collected from individual education establishments and the published figures include estimates for non-response.

We do not currently hold attendance statistics for the number of pupils who are classed as disadvantaged.

The attendance of children with an education, health and care plan should be based on an individual risk assessment, carried out and regularly reviewed to judge whether they are best supported at school or at home at this time. Attendance may not be appropriate for some children, including because of health considerations for them and their family. Full guidance on the definition of vulnerable children and expectations around attendance is available at:
