School Attendance Codes Explained, From I to U
Only four codes count as unauthorised absence. What each code means, which ones are taken out...

A school cannot simply put your child on reduced hours. Every child of compulsory school age is entitled to full-time education. A part-time timetable is allowed only in very exceptional circumstances, only where it is in the child’s best interests, only temporarily, and only where the school and a parent the child normally lives with have both agreed it, including the exact days and times. It must not be used to manage behaviour. If your child has an EHC plan, the council’s duty to secure the provision in it does not shrink because the hours did.
It usually arrives as a suggestion rather than a decision. Things are difficult, everyone is struggling, so how about mornings only for a while. Most parents say yes, because it sounds like help and because the alternative on the table is worse.

It is one lawful way to educate a child in England and it sits alongside school, not above it. It suits some families and not others. Plenty of children are happy and well taught at school, and plenty of the parents who write to us end up staying and getting things put right there instead.
Nothing on this page is an argument for taking your child out. It is not an argument for keeping them in either. We write the law and the numbers down plainly so that whichever way you go, you go knowing what is actually true, because most people are handed a decision and almost none of the picture.
If school is the right place and something in it is going wrong, that is usually the thing worth sorting first. Your child’s right to an education is the same either way.
Sometimes it is help. A short, agreed, reviewed reduction can be exactly the right thing while a child recovers or reintegrates. The problem is what happens when there is no end date, no plan, and no review, and mornings only quietly becomes the arrangement for a year.
Here is what the guidance actually permits, so you can tell the difference.
Paragraph 65 of the July 2026 guidance is unambiguous:
“All pupils of compulsory school age are entitled to a full-time education suitable to their age, aptitude and any special educational needs they may have.”
Education can be split between school and somewhere else, for example under section 19 of the Education Act 1996 or sections 42 or 61 of the Children and Families Act 2014, but that is still full-time education. It is not the same as being sent home at lunchtime with nothing arranged for the afternoon.
Paragraph 66 sets the test. There may be a need for less than full-time education:
“In very exceptional circumstances, where it is in a pupil’s best interests … through a temporary part-time timetable to meet their individual needs.”
The example the guidance gives is a medical condition that stops a child attending full-time, where reduced hours let them access as much education as possible. And then it says the thing that matters most:
“A part-time timetable should not be used to manage a pupil’s behaviour.”
If reduced hours have been put forward because of behaviour, that is outside what the guidance allows, whatever it is being called.
Paragraph 67 says a part-time timetable should:
Two more expectations sit alongside. Where the child has a social worker, the school is expected to keep them informed and involved. Where the child has an EHC plan, paragraph 69 says the school should discuss the timetable with the local authority so the support package can be reviewed quickly.
For schools maintained by a local authority, and special schools not maintained by one, this is not only guidance. Under regulation 11(6) of the School Attendance (Pupil Registration) (England) Regulations 2024, leave of absence for a part-time timetable can be granted where the school and a parent the pupil normally lives with:
“have agreed that, exceptionally, the pupil should temporarily be educated only part-time and have agreed the times and dates when the pupil will, during the period of temporary part-time education, be expected to attend the school.”
Agreement on the specific times and dates is part of the legal test, not an administrative nicety. Schools that do not have to follow regulation 11 must still record it the same way, on the same basis of agreement.
The sessions your child is not in school must appear on the register, normally as code C2, the leave of absence code for a compulsory school age pupil on a part-time timetable. Code X is used for a pupil who is not of compulsory school age.
This matters for two reasons. Recorded properly, those sessions are authorised, so they do not build towards a fine. Recorded properly, they are also visible, which makes it much harder for a long-running arrangement to go unnoticed. The guidance also now makes clear that registration must be taken at the same time for all pupils, including those on part-time timetables.
If you are not sure what has been recorded, ask for a copy of the attendance record. Our guide to the codes explains what each one means.
This is the point most worth holding on to. Section 42 of the Children and Families Act 2014 says that where an EHC plan specifies special educational provision:
“The local authority must secure the specified special educational provision for the child or young person.”
The only exception in the section is where the parent or young person has made suitable alternative arrangements themselves. Reduced hours at school do not remove the duty, and they do not reduce it in proportion. If the plan says a certain amount of something, that is what has to be secured.
Where a child is disabled within the meaning of the Equality Act 2010, there is also a duty to make reasonable adjustments under section 20 of that Act. The attendance guidance points schools at it directly and says adjustments should be agreed with, and regularly reviewed with, the child and their parents.
Free, impartial help exists for this and it is worth using before things escalate. Your local SENDIASS supports parents through exactly these conversations, and IPSEA publishes the clearest free legal explanations of SEND law in England.
A part-time timetable is sometimes the last step before a child stops attending altogether. If that is where you are, two things are worth reading. The section 19 duty is your council’s legal responsibility to arrange education for a child who cannot attend. School refusal and school avoidance covers what tends to help before that point.
In 2024/25, 176,361 children in England missed at least half of school, and rates vary enormously between areas. See the figures for your council.
Yes, but only narrowly. The statutory guidance allows one in very exceptional circumstances, where it is in the child’s best interests, on a temporary basis, and only where the school and a parent the child normally lives with have agreed it, including the days and times. It should not be used to manage behaviour.
No. Agreement from the school and from a parent the child normally lives with is part of the test, and for maintained and non-maintained special schools that agreement, including the specific times and dates, is written into regulation 11(6) of the 2024 Regulations.
It is meant to be temporary and to run for the shortest time necessary, with regular reviews and a proposed end date. It can be extended through review, and the guidance accepts a child with a long term health condition may need one for a prolonged period, but there should always be a plan and a date.
Normally code C2, the leave of absence code for a compulsory school age pupil subject to a part-time timetable. Code X applies to a pupil who is not of compulsory school age. Those sessions are authorised, so they do not count towards a penalty notice.
No. Section 42 of the Children and Families Act 2014 requires the local authority to secure the special educational provision specified in the plan. The only exception in that section is where the parent or young person has made suitable alternative arrangements. Fewer hours in school does not reduce the duty.
Not for the agreed sessions, because they should be recorded as authorised leave of absence under code C2. Fines follow unauthorised absence. If those sessions have been coded as unauthorised instead, that is worth querying straight away.
