School Years
Term-time absence, and what a missed school day actually costs
The rules differ wildly by country and the cost is not spread evenly across the calendar. Both are worth knowing before anything is booked.
The points below about school absence are ordered by how much difference they make, not by how often they get repeated.
What matters most
- Penalties for term-time absence vary enormously between countries and regions.
- Attendance percentages sound better than the days they represent.
- The research signal is about persistent absence rather than a single week.
The rules are local and unevenly applied
Some countries fine families for unauthorised term-time absence, some leave it to school discretion, and some have no mechanism at all. Even within one country the enforcement often varies by region and by school, which is why other parents’ experience is unreliable evidence.
The only useful source is your own school’s published policy and your local authority’s rules. Asking before booking costs one email and occasionally saves a substantial sum.
The percentage hides the days
Ninety per cent attendance sounds respectable and is roughly a half-day missed every week across a year. Schools quote cumulative figures precisely because the accumulation is the point, and a single figure makes a pattern visible that individual absences do not. Parents commonly discover their child is flagged as a concern at a percentage they would have described as fine.
When it is going badly, knowing how the figure is calculated where you are prevents an unpleasant surprise in a letter.
The cost is not evenly distributed
A week during an exam period, at the start of a new topic, or in a subject that builds sequentially costs far more than the same week elsewhere. Teachers can usually tell you which weeks are load-bearing if you ask before you book rather than after. Practical assessments, coursework deadlines and trips are the items that genuinely cannot be repeated.
The end of a summer term and the middle of a February are not equivalent, whatever the attendance figure says.
Catching up is not the same as being there
Worksheets sent home carry the content and not the explanation, the questions other children asked, or the correction of a misunderstanding as it happened. Older students can often self-recover from notes; younger children generally cannot, because the teaching is the part they missed. Asking specifically what was covered, rather than for the work, produces something more useful.
A week away is usually recoverable, which is a different statement from costless.
Do not game the illness rules
Sending a genuinely unwell child in to protect an attendance figure is common, unpleasant for the child and unhelpful for everyone else in the class. Schools publish exclusion periods for infectious illnesses, and following them is a public health matter rather than a preference.
Where a child has a chronic condition, most systems have a route to record medically related absence differently, and asking about it is worth doing early. Anything about whether a child is well enough to attend is a question for a doctor rather than for an attendance policy.
Take what is useful and ignore the rest — nobody is marking this.
Persistent absence is the real signal
The associations in the research are strongest for chronic absence accumulating over months, not for a single family holiday. If absence is creeping up through repeated short illnesses or reluctance, the underlying cause is the thing to look at rather than the total.
Anxiety, undiagnosed learning difficulty, bullying and untreated health conditions all show up first as an attendance figure. Raising it yourself, before the school raises it with you, changes the tone of the entire conversation.

The takeaway
Check your own local rules in writing, ask which weeks matter, and watch the pattern rather than the single trip.
The thing they remember is rarely the thing you were worrying about.
Questions readers ask
Will the school authorise a holiday?
It depends entirely on your country and often on the individual head. Ask in writing before booking, and ask what happens if it is refused, because the answer varies from nothing to a fine.
Is a week away really that damaging?
For most children, occasionally, no. The evidence points at repeated absence rather than at one trip, and the timing within the year matters more than the fact of it.
