Salary range: £17,500 to £40,000
How to become a non-destructive testing technician
You can get into this job through:
- a college course
- an apprenticeship
- working towards this role
You might be able to find a place as a trainee technician after doing a qualification at college. Relevant courses include:
- Level 2 Certificate in Welding
- Level 3 Diploma in Engineering
- Level 3 Extended Certificate in Applied Science
- T level in Design, Surveying and Planning
You’ll usually need:
- 2 or more GCSEs at grades 9 to 3 (A* to D), or equivalent, for a level 2 course
- 4 or 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, for a level 3 course
- 4 or 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, including English and maths for a T level
You could complete an intermediate apprenticeship for non-destructive testing (NDT) operators or an advanced apprenticeship for NDT technicians.
You’ll usually need:
- 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, including English and maths, for an advanced apprenticeship
- some GCSEs, usually including English and maths, or equivalent, for an intermediate apprenticeship
You can do a foundation degree in non-destructive testing (NDT) if you’re already working in this area, for example in an engineering workshop or a materials testing lab.
The course is offered by the University of Northampton and is done by distance learning. You can go on to complete an NDT degree with them to qualify as an engineer.
You can find out more about this career through The British Institute of Non-Destructive Testing.
