My dd 16 year 12 is tracking about 84% attendance. She often finds the noise of a big secondary overwhelming and has to get out. It’s just normal noise, but she often finds it overwhelming. I’ve bought her some earphones.
But most of her missed days are due to anxiety or inability to deal with noise or over stimulation. She works hard, but it seems that disability isn’t a reason for disallowing attendance which seems madness.
