Low Attendance in Mainstream schools IS often due to I'll health. My DS2's attendance this year (his worst ever) was just 88%. The EWO wasn't called however - a) I had done a 40 minute bus journey each day AND had to arrange for someone to sit with DS2 while I did so to get his older brother there, and b) He was severely immune suppressed due to strong asthma medication and chickenpox was going around the school, and on the advice of his respiratory consultant, he was kept off school until 5 days after the last reported case...
There ARE many, many DC in mainstream who may have quite severe medical and health issues requiring time off. I find the suggestion that because my DC's ate in mainstream education, they can't be ill enough to have poor attendance offensive, misguided and ill-informed.
I have a DD with two leaky heart valves that will need replacing through open-heart surgery when she is 16 (she is 14 right now) in mainstream. Her cardiac consultant is nearly 100 miles away. She often has to miss 2-3 days of school to go there. She is also partially deaf. Her ENT and Audiology clinics ONLY run in school times. She has other health issues that require Physio and OT, again the clinics are run during school hours only. She has to see a developmental Paed. Again, clinic is school hours only. She has to see a Paed Neuro for her absence seizures, 60 miles away.
Then there is the associated travel times involved when you rely on public transport.
My DS2 also sees the developmental Paed, SALT, Orthotics, Physio, OT, ENT, Audiology, asthma nurse, respiratory consultant, and probably more I can't remember without looking in my diary...
They are both in mainstream. Can you now see why someone saying that DC in mainstream don't have serious health issues is offensive to me?!
And I'm glad that at our school, attendance awards are given out for attendance over 95.5%. Gives most DC's (though not mine, frequently) the chance to achieve them.
