DCs were distraught (no exaggeration) earlier this term to catch chickenpox, because it meant they had to stay off school and wouldn't be able to get an attendance award. They're 5 & 7.
Their school makes a BIG thing about achieving 100% attendance for the whole year. The 'winners' get an award in the end of year assembly and then go to a special tea party with senior staff on the last day of term. Only 5% of kids achieved 100% this year.
AIBU to think that it's wrong to reward attendance at primary level because generally, kids aren't absent due to anything they control. It's either genuine sickness (which is more prevalent in younger children), or family holidays, which the parents have decided to take. Fair enough to encourage a truant 14-year old, bit not little ones. The kids are so upset when they can't go to school.
