Vulcan teenagers went to Vulcan masters to learn the ways of logic and how to suppress emotion. For example, Tuvok was sent to study under a Vulcan master when he was a teenager and had rebelled against Vulcan discipline. (VOY: "Gravity") In 2368, Tuvok bought a meditation lamp from a Vulcan master, who charged double the price when he saw the Starfleet insignia of Tuvok and Janeway. (VOY: "The Gift") Tom Paris condescendingly described Tuvok as "the Vulcan master" in 2374, and relished Harry Kim "putting him down a peg." (VOY: "Demon")
