GCSEs and A-Levels

Forensic scientists typically need 5 GCSEs at grades A*-C, including English and Maths. A-Level courses in a science-related subject are also beneficial.

Degree and specialist courses

The easiest way to get into a career as a forensic scientist is by completing a degree or course in forensic science, a course in biology, or another science-based subject.

    Having an inquisitive mind and the patience to work hard to uncover the evidence you need is essential, as is the ability to be open-minded about the situation and evidence you are analysing. As you will be working with other professionals such as crime scene investigators, being patient when waiting on other evidence and using your communication skills is essential in this line of work.

  • Being able to handle stress

    When visiting crime scenes, being able to handle stressful or distressing environments is a must, as well as learning to handle tough cross-examination of evidence in court. Getting some work experience in the forensic science, law enforcement, or criminal justice sector is a great idea, as it will show dedication and that you are aware of the environment you will be entering into.

Being able to pay attention to every detail is vital, including when physically analysing data and trace evidence as well as being aware of how you interact with the crime scene or a laboratory setting. Using equipment that protects you, others, and the evidence is essential, and always being mindful of this means you could be well on your way to becoming an expert forensic scientist.

What Does a Forensic Scientist Do Day-to-Day?

In your role as a forensic scientist, you will be in the lab uncovering scientific evidence to help criminal investigators to find out what exactly happened at the crime scene, presenting evidence, and acting as an expert witness for court cases.

It’s worth bearing in mind that forensic science is a detail-oriented and professional role, so if you love the glitz and glamour of shows like CSI, bear in mind that it can take a while to decipher what has actually happened in a criminal investigation.
