How Do I Become a Forensic Psychologist?

Forensic psychology is one of the most fascinating and impactful branches of psychology. It combines the science of human behaviour with the criminal justice system and law. If you are interested in the reasons behind why people commit crimes, how mental health can impact court decisions or how criminals can be rehabilitated, forensic psychology may be the career for you.

What does a Forensic Psychologist do?

A forensic psychologist applies psychological theory and methods to understand and address issues in the criminal justice system. The field of forensic psychology bridges the gap between psychology and law, helping other professionals such as police, lawyers and judges make informed decisions.

Some key responsibilities of the role include:

  • Assessing offenders: Evaluating the mental state of individuals accused of various acts. This can include deciding whether someone is fit to attend a trial or assessing the risk of reoffending.
  • Providing expert testimony: Appearing and speaking in court as expert witnesses to explain psychological; findings or diagnoses in a legal context.
  • Supporting rehabilitation: You may work in a prison or hospital, designing and delivering treatment programmes to reduce reoffending and support behaviour changes.
  • Research and policy: You may focus on studying criminal behaviour, various interventions or the psychological impact of prisons. This study can inform future policy or practice.
  • Victim support: You can also work with victims of crimes or help police with criminal profiling and interviewing techniques.

The goal of forensic psychology is to apply psychological knowledge to promote justice, reduce harm and improve outcomes for individuals and society.

Steps to becoming a forensic psychologist

  • GCSEs – Having a pass grade in maths, science, english and psychology (if available) is a great start. Aim for atleast five GCSEs at grades 9-4 to progress to A-levels or equivalent qualifications.
  • A-Levels – A-Level Psychology is of course the obvious choice if interested in forensic psychology. Taking biology, sociology, law or mathematics can also be valuable. Aiming for Grades BBB or higher would be super.
  • Undergraduate degree – Most students complete a BSc (Hons) Psychology, which typically takes three years to complete. The degree covers core areas such as cognitive, developmental, social and biological psychology as well as statistics and research.
  • Postgraduate study in forensic psychology- You will need to also complete a BPS-accredited masters degree in forensic psychology. This takes a year, or two years if you decide to do it part-time, and deepens your understanding of psychology theory and practice in the context of criminal justice.
  • Stage 2 Training or Doctorate – To qualify for full status as a forensic psychologist, you need to complete stage 2 training or the doctorate, which involves supervised practice under a qualified forensic psychologist. Successfully completing this allows you to register with the Health and Care Professions Council (HCPC) as a forensic psychologist.

Career progression and job roles

After qualifying, you may begin as an assistant psychologist or trainee forensic psychologist in the NHS, prison service, police or a private sector. From here, you can progress to rules such as a forensic psychologist (HCPC), a senior psychologist, a consultant forensic psychologist or head of psychology services. You may also decide to move into policy work or research, or choose to specialise in violent behaviour, sexual offending or victim support.

Career opportunities and further training

There is great demand for forensic psychologists across multiple settings. This includes charities and rehabilitation services, universities, police forces and courts, NHS forensic mental health units and HM Prison and Probation services. Continuous professional development is crucial throughout the career of a forensic psychologist. You may choose to train further in Cognitive Behavioural Therapy, Risk assessment tools, Trauma-Informed care, supervisory and leadership skills or advanced research methods. In addition to enhancing your expertise, these extra skills can widen your career options e.g. management, research or consultancy.

Becoming a forensic psychologist evidently requires empathy, dedication and intellectual curiosity. To become one, there is no quick route. It often takes seven to ten years from attaining GCSEs to being fully registered. However, this long journey leads to a career that makes a real difference in people’s lives and society. This is a great career option for you if you’re interested in the human mind, promoting justice and helping criminals change for the better.
