Due to the absence of age restrictions in most universities, both fresh graduates and working professionals can apply for an MSc in Management degree. Whereas in some institutions, there are age preferences for specialized or executive programs which do require work experience. Younger applicants are common in their early to mid 20s, but older candidates with relevant professional experience are also welcomed especially in career change or leadership oriented tracks.
However, for an applicant that is significantly older, there is a need to justify in detail why they want to pursue a certain degree and how it relates to their career goals. Take note that certain countries do impose age restrictions to certain scholarships or visa applications. But in reality, most universities will prioritize academic achievement, work history, and professional goals over age. To be on the safe side when it comes to age restrictions, it is smart to consult admission offices of the particular school you are considering attending. In any case, MSc Management is very versatile and can accommodate students of different ages.
