Securing the scene. Dusting for prints. Gathering evidence that could help put dangerous offenders behind bars for life. The job of crime scene investigators is not only fascinating and varied, it’s essential in making sure that justice is done. Although it’s one of the most interesting careers out there, life as a CSI isn’t for the faint of heart!

This level 3 course is ideal for anyone working towards a career not only in crime scene investigation, but in criminology, forensic science, or education and training. All these professions value an eye for detail, analytical skills and a problem-solving instinct – and you’ll gain every single one of them by studying with us.

You’ll learn everything from tracing evidence to investigating fire scenes, firearms, major incidents and much more. You don’t need any prior qualifications, and you can study in your own time, at your own pace. This course is a stepping stone to further education or a career on the front lines of justice.

What you'll learn

Unit 1 - Unit 1 - History of Crime Scene Investigation in the UK and How to Approach Crime Scenes

Discover the origins of crime scene investigation. You’ll look at investigation procedures and what CSI should do when arriving at a crime scene. You’ll learn about where to record information gathered from injured parties, which charitable organisation provides assistance to victims, and when crime scene reports should be completed. You’ll also ascertain what goes on the bottom of every statement you write, what should be attached to forensic evidence collected from scenes, and what is meant by ‘hearsay evidence’ and ‘quartering a room’. Finally, you’ll identify what must be disclose by the prosecution and defence, types of computerised evidence management systems, equipment of CSI, and when an audit trail should begin when using a digital camera.

Unit 2 - Unit 2 - Trace Evidence

Gain a broad understanding into various types of trace evidence, such as fibres, glass, hairs, paint and soil. You’ll look at factors that affect how such evidence is recovered from a crime scene. You’ll also examine impressions or marks left at the scene of a crime from footwear, instruments (e.g. a crowbar), gloves and tyres. You’ll also learn about the history of DNA, and what it takes to recover DNA samples (e.g. saliva) from crime scenes. This unit will also boost your knowledge of fingerprints, from detecting them at scenes, to their individual characteristics, and their use to identify suspects. There will also be case studies to aid your progress.

Unit 3 - Unit 3 - Investigating a Fire Scene, Firearms and Major Incidents

Acquire knowledge of fire scene investigations, the role of agencies involved, why a CSI might suspect arson, and how to recover samples from the scene itself. You’ll look at firearms and explosives, as well as the recovery of discharge residue. There will also be a case study for you to work through to support your learning.

Unit 4 - Unit 4 - Leadership and Management in Crime Scene Investigation Including Health and Safety at Crime Scenes

Identify background knowledge to the forensic examination of a crime scene. You’ll look at types of cordon put in place at scenes, what members make up a crime investigation team, as well as learn some key initialism, such as CSM. You’ll also explore organisations that provide advice during major investigations, how and why crime scene managers conduct team evaluations, and understand the principle of Maslow’s Hierarchy of Needs in relation to the management of a crime scene team.

Unit 5 - Unit 5 - Other Sources of Evidence

Recognise which four groups biological weapons are divided into. You’ll be able to explain what CBRN stand for, as well as how CSI should package hardware, software and devices in cyber investigations. You’ll finally determine types of evidence to indicate drug use, and what items a you should consider removing as evidence from a scene of sudden infant death.

Unit 6 - Unit 6 - UK Criminal Law Courts

Courses Taught by Experts


Education and Childcare

My 30-year stride in education started with childminding, to working with pupils with Special Educational Needs and Disabilities. I then tutored in a national reading programme and went on to become a Higher-Level TA. I’m elated to say I graduated with a First-Class BA Honours Degree when I was 50 – living proof that it’s never too late to chase your dreams!



Early Years

Beginning my career as an early years practitioner inspired me to step into the world of teaching. I have since elevated my skillset through a range of qualifications including L3 in Assessing Vocational Achievement, L3 in Education & Training and L4 in Internal Quality Assurance. I’m a big kid at heart; I love Disney movies and also dabble in photography.  



STEM and History of Art

Marine biology, jellyfish conservationist, hairdresser, fitness instructor… I have an eclectic backstory! Art is my passion and one of my proudest moments was achieving my Masters in Fine Art. I then requalified as an Art teacher to share my knowledge with my students. For most of my career, I’ve supported vulnerable students with additional needs such as SEMH and SEN.



Counselling and Psychology

I always knew that a career focused around helping people achieve their goals was perfect for me. That’s why I became a tutor. I love to see my student’s confidence flourish as they progress through their courses. It’s important to help them fit their learning goals around their personal commitments so they have the best chance of success! 

Kelly, tutor


Health care

For 10+ years, my passion for helping learners develop and grow has driven my career as a teacher. To help me progress even further, I am currently studying to achieve the IQA award. I love reading and I’m a self-professed Harry Potter fan. Talk to me about all things history, rock music, tattoos and true crime podcasts.
