I know a few teachers who decided to pursue graduate degrees, but not in the exact same area of study as their Bachelor degrees. For instance, if a student majors in Early Childhood Education, the pursuit of a Master's degree in something like Secondary Education, Educational Leadership, or Higher Administration may allow for more career options. That person wouldn't feel "boxed in" one specific career under the wide umbrella field of Education.
Some nurses decide to take their expertise to another level by attending Physician's Assistant (PA) school. The need to stay in the same field was replaced by ambition to be more, do more, mean more, and make more.
I chose to pursue my Master's in Adult Education and Community Leadership so that I can venture into an educational background, even with my undergraduate degree being in a health profession (Radiologic Sciences). Being a clinical preceptor within my field, as well as an adjunct anatomy instructor, helps to make my career well-rounded and helps with my long-term goal of being a clinical coordinator at some point. I have other goals outside of the health field altogether. The blend of both degrees helped me become scholarly published as well.
Overall, I advise that students fully consider all aspects of their potential graduate studies. There is nothing wrong with pursuing the same program if you are sure that it benefits your career goals. Having a concentration within that program may expand your range as well, while giving you expertise in a particular area. Just know that your options are limitless, and that it comes down to how well you are able to make the degree work for you. There are no guaranteed positions solely because you have a Master's or Doctorate. But also know that you are not limited by the degrees you earned either. Many people work in areas they never pursued, but that's another topic.
