If the form asks you to describe your child’s disability, it’s because the support or service is only available to disabled children.
If it asks for your child’s age, it’s probably because it’s only open to children within a certain age range.
Some criteria are simple, like age. Others are more complicated. For example, the criteria for disability benefits might depend on whether your child’s needs reach a particular level of difficulty or require a certain amount of care. Showing this clearly can take time and careful thought.
If it doesn’t, think twice about including it, or find a clearer way to link it back to what the form is actually asking for.
Before you submit your form, take a moment to look back at the criteria and check that you’ve provided information or examples that show how your child meets them.
If you don't know what the criteria are for the form you are completing, and you can't find them on google, then don't hesitate to ask whoever gave you the form in the first place.
