When you talk about the methods, characteristics, and attitudes of a person holding a job that requires higher education or advanced training, you're talking about their professionalism.

The noun professionalism is usually used to describe the type of behavior you would expect from a professional person. For example, showing up to work on time, and focusing on the task at hand. And not fighting with your coworkers (unless you're a professional wrestler).
