Admissions
To gain entry to the school, pupils from primary schools in the local area are invited to do the 11-plus exam. Entry to a grammar school usually requires a score of 121/141, though pupils who gain scores of below 121 are invited to appeal their case. Prospective pupils who did not take the 11+ (e.g. those who join in later years) also take the school's own entry test.
