From the UK National Careers Service page for Forensic Scientist:
Entry requirements
To start work, you would usually need a degree or postgraduate award in forensic science. You can also get into this career with a science-based degree. Degrees related to chemistry, biology, life sciences, applied sciences or medical sciences are likely to be the most appropriate, depending on the type of forensic work you want to do.
If you want to specialise in electronic casework (recovering data from computers, mobile phones and other electronic equipment), you may be accepted with experience and qualifications in computing, electrical engineering, electronics or physics.
There may be opportunities to start with a company as a forensics lab support assistant if you have qualifications, such as HND, BTEC or A levels in science, together with relevant work experience.
As with all forensics vacancies, there will be tough competition for jobs.- See more at:
