'The Knowledge' is the in-depth study of street routes and places of interest that taxicab-drivers in London must complete to obtain a licence to operate a black cab. It was initiated in 1865, and has changed very little ever since.
It is the world's most demanding training course for taxicab-drivers; and applicants will usually need at least 12 'Appearances' (attempts at the final test), after preparation averaging 34 months, to pass the examination. Whilst learning 'The Knowledge', would-be taxicab-drivers use the famous A-Z street maps to help them master the labyrinth of over 26,000 streets within a six mile radius of Charing Cross.
Today A-Z supplies maps to Knowledge Schools across London as folded paper, flat sheet and laminated maps so that the black cab drivers of the future can reach the high standard Londoners and visitors alike have come to expect from them.
