Caterham School for Girls
From Tardis Wiki, the free Doctor Who reference
Caterham School for Girls was a highly reputable boarding school to which Dr Lavinia Smith sent her niece and ward Sarah Jane, later to become a companion of the Third and Fourth Doctors. It was, at the time, run by a strict but highly competent headmistress who shared Lavinia's feminist convictions. (PROSE: The Roving Reporter)
