Upon completing the relevant training course, new barristers ("readers") are required to spend a period of months "reading" in the chambers of an experienced barrister, called the reader's "tutor" (in New South Wales) or "mentor" (in Victoria) (historically, this experienced barrister was called the new barrister's "pupil master"). This "reading" period serves as a kind of practical apprenticeship for the new barrister, who works in the same chambers as their tutor/mentor and is able to learn by observing their tutor/mentor, as well as actively seeking their guidance.
