Sibling Priority Admission Appeals

Each school defines ‘sibling’ in its own admission arrangements

Most schools give higher priority to a child with an older brother or sister already attending (or due to attend) at the time of admission — but exactly who counts as a sibling is set out in the school’s own published admission arrangements, not a single national definition. Some definitions include step-siblings, half-siblings, or children living in the same household who aren’t related by blood; others are narrower.

Where disputes usually arise

• Whether a step-sibling or half-sibling living in a different household counts under this school’s specific definition
• Whether the sibling will genuinely still be on roll at the school at the time the younger child would be admitted
• Whether the sibling relationship was clearly evidenced at the time of application

What strengthens this ground

The school’s own published sibling definition, set directly against your actual family circumstances and proof of the relationship and shared address. If your situation clearly meets the published definition and wasn’t recognised, that’s a concrete, checkable point for the panel — much stronger than arguing the definition itself should be different.

Where it tends to fail

Arguing that a sibling definition is unfair, rather than that it was misapplied to your specific circumstances, is a weak version of this ground — panels are checking whether the published policy was correctly applied, not re-writing the policy itself.
