Two school days missed each month during your school life adds up to one whole year of school lost.
If your child has a holiday of 1 week during term time and 10 days' illness, they will miss 75 hours of education in the academic year. If this pattern were to be repeated throughout your child's school life, they would miss almost a year of their education.
If you're 15 minutes late every day, you lose two weeks of learning by the end of the school year.
90% attendance may look impressive. However, it means missing 19 days of education a year.
