90% attendance - Jack's story
Jack is a child with a 90% attendance rate. His mum and dad think this is quite good and are surprised when they're told he is considered to be "persistently absent".
90% attendance means that, on average, Jack has missed one half-day of school per week.
Over a whole school year Jack would miss four weeks of lessons. He would also spend more time away from school over the year than in school:
If his attendance for all the years he went to school was 90% he would miss 209 days of school - that's more than a whole school year.
