When doctors of foreign countries learn English, they need to learn the names of their tools, naming conventions, and methodologies of their profession before one can ethically perform surgery. ESP courses for medicine would be relevant for any medical profession, just as how learning electrical engineering would be beneficial to a foreign engineer. Some ESP scholars recommend a "two layer" ESP course: the first covering all generic knowledge in the specific field of study, and then a second layer that would focus on the specifics of the specialization of the individual.[6]
