What you'll do
Day-to-day tasks
In this role you could:
- perform blood grouping and DNA profiling
- analyse fluid and tissue samples for traces of drugs and poisons
- examine splash patterns and the distribution of particles
- analyse handwriting, signatures, ink and paper
- provide expert advice on explosives, firearms and ballistics
- research and develop new technologies
- recover data from computers, mobile phones and other electronic equipment
- attend crime scenes, like a murder or fire
- give impartial, scientific evidence in court
Working environment
You could work in a laboratory, in a court or visit sites.
Your working environment may be emotionally demanding.
You may need to wear protective clothing.
Career path and progression
With experience, you could move into management and direct other forensics staff as a forensics manager or casework examiner.
You could also work as a reporting scientist, acting as an expert witness in court.
What it takes
Skills and knowledge
You'll need:
- to be thorough and pay attention to detail
- patience and the ability to remain calm in stressful situations
- the ability to accept criticism and work well under pressure
- the ability to think clearly using logic and reasoning
- knowledge of public safety and security
- excellent written communication skills
- the ability to work on your own

Related subjects
Most relevant
- Chemistry - Forensic scientists analyse drugs, poisons, and unknown substances found at crime scenes. They use techniques like chromatography and mass spectrometry to identify what a substance is made of and where it might have come from.
- Biology - Forensic scientists carry out DNA profiling, blood grouping, and tissue analysis to help identify victims and suspects. Understanding how the human body works also helps when examining how injuries occurred.
- Mathematics - Forensic scientists use statistics to interpret evidence and explain the likelihood of a match in court. They also use mathematical modelling to reconstruct events, like the trajectory of a bullet or the spread of a fire.
- Physics - Forensic scientists apply physics when examining ballistics, explosives, and the way particles and debris distribute at a crime scene. Understanding forces and materials helps explain what happened and in what order.
- Computer Science - Forensic scientists increasingly work with digital evidence, recovering deleted data from phones, laptops, and other devices. This is one of the fastest-growing areas of forensic work.
Also relevant
- Law - Forensic scientists give evidence in court as expert witnesses and need to understand how legal proceedings work. Their reports must meet strict legal standards to be admissible as evidence.
- Psychology - Forensic scientists often work alongside criminal psychologists and need to understand how human behaviour can help explain what happened at a crime scene. This is especially important in cases involving violent or complex offences.
- English Language - Forensic scientists write detailed scientific reports that need to be understood by non-scientists, including lawyers, judges, and juries. Being able to communicate complex findings clearly can make the difference in a case.
- Design and Technology - Forensic scientists examine physical evidence like tools, materials, and manufactured objects. Understanding how things are made and how materials behave helps when analysing what was used in a crime and how.
- Electronics - Forensic scientists who specialise in digital forensics work with circuit boards, storage devices, and electronic systems. Understanding how electronic hardware works is essential for recovering evidence from damaged or tampered devices.
How to become
You can get into this job through:
- a university course
- an apprenticeship
- applying directly
You can do a degree or postgraduate qualification in:
- forensic science
- a related subject like chemistry, biological science, physics or medical sciences
Entry to jobs is competitive, so it may help to choose a university qualification accredited by The Chartered Society of Forensic Sciences.
Entry requirements
You'll usually need:
- 2 or 3 A levels, or equivalent, including chemistry
- a degree in a relevant subject for postgraduate study
More Information
You could apply to do a Degree Apprenticeship, such as:
- Scientist Level 6
- Research Scientist Level 7
It will help if you do your aprenticeship with a company that provides forensic science services, or with a police force that has its own in-house lab facilities.
Entry requirements
You'll usually need:
- 4 or 5 GCSEs at grades 9 to 4 (A* to C) and A levels, or equivalent, for a degree apprenticeship
More Information
You can apply directly to forensic services providers if you've got a lot of lab experience, and qualifications in science, especially chemistry.
Career tips
If you want to specialise in recovering data from computers and mobile phones, you'll need relevant experience and qualifications. Useful subjects include computing, electrical engineering, electronics or physics.
Professional and industry bodies
You can join The Chartered Society of Forensic Sciences for professional development and advice. The society has student membership, for undergraduates aiming to get into a forensic science career.
