Understanding School Attendance and Why It Matters So Much

Missing just one day a fortnight means your child misses 10% of their education. Here's what the attendance data shows, what schools expect, and how to improve attendance.

The Numbers That Matter

Here's a fact that surprises many parents: missing just one day a fortnight means your child has attendance of 90%. That sounds reasonable, but it actually means they miss 19 days — nearly four weeks of school every year.

Over a primary school career (Reception to Year 6), that adds up to 133 days missed — more than two-thirds of an entire school year.

The data on the impact is clear:

  • Pupils with attendance above 95% are significantly more likely to achieve the expected standard at KS2
  • Just 10 days' absence per year is linked to a drop of approximately half a GCSE grade across all subjects
  • Persistent absentees (below 90% attendance) are roughly three times less likely to achieve five good GCSEs

What Schools Monitor

Overall attendance

Schools track each pupil's attendance as a percentage. The national average is typically around 93-94%, though this varies year by year.

Persistent absence

A pupil is classified as a persistent absentee if their attendance falls below 90%. Schools are required to identify and support persistent absentees, and Ofsted looks closely at persistent absence rates.

Severe absence

A pupil is severely absent if their attendance is below 50%. This is a safeguarding concern.

Authorised vs. Unauthorised Absence

Authorised absence

The head teacher can agree to authorise absence for:

  • Illness (though for mild complaints like colds, schools generally expect children to attend)
  • Medical or dental appointments (where possible, arrange these outside school hours)
  • Religious observance
  • Exceptional circumstances (funerals, family emergencies)

Unauthorised absence

Includes:

  • Holidays during term time (in most cases)
  • Unexplained absence
  • Arriving late after registration closes
  • Shopping trips, birthdays, day trips

Term-Time Holidays and Fines

Since 2013, head teachers can only approve term-time absence in exceptional circumstances. The definition of "exceptional" is at the head teacher's discretion, but routine family holidays rarely qualify.

If absence is unauthorised, the local authority can issue a penalty notice (fine):

  • £80 per parent, per child if paid within 21 days
  • £160 if paid within 28 days
  • Failure to pay can result in prosecution

Since September 2024, national framework changes mean fines are applied more consistently, with a maximum of two fines per parent per child in any three-year period before alternative action is considered.

Supporting Good Attendance

At home

  • Establish routines — regular bedtime, bag packed the night before, consistent morning routine
  • Set expectations — school attendance is non-negotiable except for genuine illness
  • Address anxiety — if your child doesn't want to go, find out why and work with the school
  • Book appointments outside school hours where possible
  • Don't keep children home for minor complaints — a runny nose isn't a reason to miss school

When illness is genuine

If your child is genuinely unwell:

  • Contact the school on the first day of absence (by phone, before registration)
  • Provide medical evidence if requested for extended absence
  • Keep the school updated

If attendance is becoming a problem

  • Talk to your child's teacher or the school's attendance officer
  • Ask about support available (e.g. mentoring, family support workers)
  • Consider whether there are underlying issues (bullying, anxiety, SEN, family difficulties)
  • Engage with the school — they want to help

Useful Resources


Every day in school is a day of learning, friendship, and growth. While there will always be days when your child genuinely can't attend, making school attendance a priority from the very beginning sets a pattern that benefits them for life.
