Even aside from the unfairness to kids with health conditions (I've got one who week never get an attendance award), is there really any benefit in reviewing kids who are feeling grotty but not absolutely awful in?
There's little benefit in attending when you feel so rough your only aim is to make it through the day, when you are dosed up on calpol to begin with, where you feel achey amd brain foggy with cold. A kid's ability to learn and retain with that will be pretty much zero and all they'll have done is spread around their gems.
Perhaps schools could look at implementing a 'work from home' system for the huge number of children that are well enough to attend, but either cannot because of school rules, or because of physical ailments like a broken leg, where a child is likely to feel well enough to learn.
My elder child was on for 100% attendance this term, until she got chicken pox. It was so mild, she felt well enough to attend throughout but obviously was not allowed to do so.
Last year her and her friend both came down with sore throats on the same day. The friend was diagnosed with scarlet fever, and was able to go back to school 24 hours after starting antibiotics. They didn't think my daughters was scarlet fever, but took a swab to check first. The school confirmed that my daughter could not return until the lab results confirmed negative. By the time we got the results her friend had been back at school for several days. My daughter did not have scarlet fever.
I have no issue with them taking a cautionary approach, but if a child is well enough to attend, they should not be punished for not being allowed to attend.
