A missed full day usually means two missed sessions.

School attendance percentage examples
These examples show how attendance percentages are calculated from realistic day and session totals.
They are designed to make the maths clearer, not to replace a school’s own attendance records.

Reviewed for general accuracy. Always check your school, local authority or official guidance for decisions.
A percentage can change quickly when the total number of possible days is still small.
Using real possible days or sessions gives the most useful estimate.
Why examples help
Attendance percentages can feel abstract when they are given on their own. Worked examples make it easier to see what the number means in ordinary terms.
They can also help when a parent or carer wants to sense-check a figure before speaking with school.

Worked examples
See the attendance maths in context
If your child has attended 19 out of 20 school days
19 / 20 x 100 = 95%
This is a common early-term example. One missed day in a short period has a noticeable effect because the total number of days is still low.
If your child has attended 60 out of 65 school days
60 / 65 x 100 = about 92.3%
Five missed days in a term can pull the figure down more than many people expect.
If your child has attended 180 out of 190 school days
180 / 190 x 100 = about 94.7%
Ten missed days in a typical school year is just under 95% attendance.
If your child has attended 189 out of 200 sessions
189 / 200 x 100 = 94.5%
This shows why session-based figures can differ slightly from whole-day estimates, especially if there are partial absences.
Guide FAQs
Common questions about this attendance topic
These answers are general information only and are not a substitute for school records or official guidance.
Can I use these examples for my own child’s attendance?
They are useful as a guide, but the best estimate comes from entering your own possible days or sessions into the calculator.
Why are some examples based on sessions instead of days?
Because many schools record attendance by morning and afternoon session, which gives a more precise picture when a child misses only part of a day.
Why does the same number of missed days affect different terms differently?
Because the percentage depends on the total possible days so far. Five missed days out of 20 affects the percentage much more than five missed days out of 190.
Are these official examples?
No. They are independent examples created to explain the maths in plain English.
