Admissions
Admission to Years 7 to 11 at KSHS is selective. KSHS states that it accepts girls in "the top 25% of the ability range". For entry into Year 7, prospective pupils sit the eleven-plus examination to assess aptitude; the test procedures are set by the school. Pupils applying mid-year in Year 7 who have not previously sat the eleven-plus can arrange to sit it. Pupils who did not meet the minimum eleven-plus score on their first sitting (either in Year 6 or mid-year in Year 7) cannot reapply until Year 8 or later. Prospective pupils in Years 8 to 11 must sit the nationally standardised cognitive ability test (CAT) for their age range (this includes verbal, non-verbal, quantitative and spatial elements). Applicants must be within the top 25% of ability in their cohort in the CAT to be eligible for a place. Entry into the Sixth Form (Years 12 and 13) at KSHS has minimum GCSE requirements but there is no admissions test.
