Can you please provide more details on this? It would be useful to know why you are asking. From what I know at this point, occult studies would be more of a subsection of a study, not the study itself. It will depend on what you are trying to get out of studying it. Please provide more details, and then you will get better answers.
Actually, occult studies fall under different academic categories, such as comparative religion, anthropology, or history. It would be possible to get a master’s or doctorate in any of this disciplines and write your thesis on the occult, then become a teacher/professor.
