This is from the website:
Academic Scholarships are offered to the highest achieving candidates in the entrance examination for entry at age 11 (Year 7) - there is no separate Scholarship exam - and are awarded for five years, until the end of Year 11.
Like most schools all the candidates are considered for scholarships and they are awarded to the highest achievers
Most scholarships do not have much money attached to them - there is more usually in bursary funds which are means tested
The majority of (bursary) applications are made before a girl enters Upper III (Year 7) and decisions on Bursaries are made following the January Entrance Examinations; therefore all bursary applications should be received by the last Friday in November. The School is aware that family circumstances may change significantly during a child's school life, so requests for applications at other times for current pupils will be considered sympathetically if funds are still available.
