The relevant part of the DAO criteria is:
3. Applicants who have a sibling at the school at the time of application, unless the sibling is in the last year of the normal age-range of the school. Note: the â€˜normal age rangeâ€™ is Years 7 â€“ 13, this being the designated range for which the school provides.
That would mean that an applicant with a sibling in year 11 at the time of application would be eligible under this criterion, regardless of what that sibling did later. This wording mirrors the county's sibling criterion, which was imposed in August 2007 by an adjudication decision
, which ruled that the previous wording,
Children who have a sibling at the school at the time of admission. Note: this would be based on a â€˜reasonable expectationâ€™ that the elder sibling will be at the school.
was not clear, objective and fair.
