Children of school-age who are on roll at a mainstream or special school must, by law, attend that school regularly and punctually.
Regular attendance is important, not just because the law requires it but also because it is the best way of ensuring children make the most of the educational opportunities available to them.
When a child is absent from school, he misses not only the teaching provided on the days when absent, but is also less prepared for the lessons on his return. This will lead to a risk of underachievement, which teachers and parents will both wish to avoid.
There may be occasions when a child has to miss school - for example, if unwell. Any other absences should be kept to an absolute minimum.
