Students often do not understand the requirements necessary to enter certain fields or job areas; assignments that acquaint them when those requirements can be very "educational"in a variety of ways. For example, it is not uncommon to encounter students who want to enter highly competitive fields like law enforcement to have little or no understanding of how difficult those jobs are to land (frequently there are hundreds of applicants per position) or that becoming an FBI agent requires graduate education in law, accounting, languages, computer science or some other advanced degree that the FBI happens to need and be age 37 or younger. Students often have unrealistic expectations about their desired careers that could stand correcting, even if they don't want to know it.
