You must have a register
All schools, except for boarding-only schools, are required to have an attendance register. You must include all pupils, regardless of their age, on this register.
In a boarding school, if you have any day-pupils, you must keep an attendance register for them. However, there's no requirement to do so for your boarding pupils.
The statutory requirements for the register are set out in the DfE's guidance on working together to improve attendance and legislation, which we refer to throughout this article.
When to take the register
You must take the attendance register at the start of the morning session of each school day and once during the afternoon session.
You're not required to take additional attendance registers in individual lessons or for before and after-school sessions.
