Not always. Grammar school catchment area rules vary between schools, and some grammar schools have no traditional catchment area at all.
Some grammar schools give priority to children who live within a defined catchment area or priority area, within a specified distance of the school, or who meet particular residency requirements. Therefore, passing the 11 Plus (11+) does not necessarily guarantee a grammar school place, particularly if your child lives outside the school’s priority area.
A grammar school’s catchment area does not necessarily follow borough or local authority boundaries. Some schools accept applications from children living outside their borough, while others give significant admissions priority to children living within a particular geographical area.
It is also important to check the school’s address and residency rules. Some grammar schools specify when a child must be living at the qualifying address and may require evidence that it is the child’s permanent home address.
Parents should therefore check the individual school’s current 11 Plus admissions policy, catchment area, priority area, distance criteria and residency requirements before applying. If you are considering a grammar school outside your local area, do not assume that passing its entrance test automatically makes your child equally eligible for a place.
