A lot of people are interested in forensic science because of all of the TV shows. This means that there are a lot more interested people than there are jobs. Also, real forensic work is not a lot like what you see on TV. There may be other careers that would interest you too. Think about WHY you’re interested in forensic science. Do you like using information to test hypotheses? Science is a great career. Do you want to apply science to help people? Public health does a lot of that. Do you like solving complex problems? Computer coding may be a good choice. Is it really law enforcement that you like? See if your city offers ride-along opportunities where you actually get to spend a shift with law enforcement officers. You can also contact your city or state crime lab to see if someone would be willing to do an informational interview. Tell them that you are a high school student who wants to explore careers in forensic science. Maybe one of their scientists would even be willing to visit you classroom, Girl Scout troop, or other organization. You can ask an adult about that kind of opportunity.
