Are you planning an extended time away from school for your child (e.g. holiday; medical intervention etc.)? For any period of time over 10 consecutive school days you are required to follow an official process. Education Queensland has a policy - Exemptions from Compulsory Schooling and Compulsory Participation - which needs to be followed if your child/children will be absent from school for this period of time or longer.
A Fact Sheet providing further details and an Application Form are provided for your information.
