Which professional designation is right for me?

Choose the correct designation for you.


Registered Science Technician (RSciTech) is aimed at those in technical roles delivering scientific services, such as technicians. It may also include those in the early stages of their career, such as apprentices.


Registered Scientist (RSci) is intended for people with a few years’ experience, working in more senior roles and with responsibility for other staff but not yet working at a chartered level.

CPhys or CEng?

Chartered Physicist (CPhys) is the qualification awarded by the Institute of Physics to practicing professional physicists.

Many physicists move into engineering at some point in their careers and so the Institute of Physics also offers Chartered Engineer (CEng) to its members.

Deciding which chartered status to go for can be tricky. Bear in mind the following when weighing your options up:

CPhys is for you if…

  • You have a physics degree and have been working in a clearly physics-related field for some time
  • You have a physics degree and are still working in science

CEng is for you if…

  • You have a degree in either physics or engineering and are working in a clearly engineering-related field
