The school moved into its first permanent home in 1589, a building in St Clement's Lane demolished to make way for the City Square in the 1930s. Among the masters here were Andrew Duncan, an academic and Presbyterian minister, and David Lindsay, later Bishop of Edinburgh, who crowned Charles I at Holyrood. Pupils were still expected to speak only Latin – to ensure which, their schoolmates were to act as "clandestine captors". Boys entered at the age of eight, and stayed for seven years (two years longer than in other Scottish schools: in 1773, this was reduced to the customary five) at which point the boy could proceed to university. A boy had probably only two teachers in all this time: each of the three assistants, known as doctors, taught one class for three years, after which the Rector would teach for two years.
