The museum studies major is a bit weird because it will not guarantee you a job. I work at a reputable museum now and some people on staff have the degree, many so not. I do not. I think it’s a good way to get your foot in the door. Based off your small snipit, I think you need to spend more time researching museums and figuring out what you want to do. Being a “director” is soooo broad - big museums have so many different departments and generally multiple directors in all departments. Do you want to just generally be a director and run a museum ? That normally comes with years of experience and generally years of working in a more specific field (curatorial, development, etc). If you are sure you want to be a curator, I do not suggest the museum studies / art admin master. From what I’ve heard and researched, it is more about how museums function administratively. At most large museums, that major will not get you a curatorial job —- curatorial jobs will come with a masters and PHD in art history or history.
If you haven’t already, look at museums you would love to work at or in a perfect world see yourself working at — look at positions that are open and positions people have at those museums and see what interests you. Look at what those people did to get their position (check their LinkedIn’s ! Or ask people at the place where you volunteer)
