Absence note to the school (from parent or guardian) advising them of your involvement in the absence of your child for a more extended period due to illness. The illness is expected to impact on attendence and/or performance in the future, which should be outlined here, and you need to get together to discuss the future.
Note: the school should be advised of a more extended absence expected as soon as you become aware of it, such as when your doctor advises you. Because of the change in ability to participate, this letter is essential to follow up, as it impacts on the school's "duty of care".
