What is Chartered scientist?

The CSci designation demonstrates a high level of competence and professionalism in science. At present there are over around 12,000 Chartered Scientists working across all sectors of science.

Being chartered is the mark of professional recognition and being a Chartered Scientist allows all scientists working at the full professional level to be recognised on an equal footing.

The designation aims to give an assurance of current competence through mandatory revalidation of CPD, and encapsulates the interdisciplinary nature of science in the 21st Century.

By benchmarking professional scientists at the same high level, CSci aims to re-engage public trust and confidence in science and scientists.

Why become a Chartered Scientist?

The CSci benefits individual scientists, the profession as a whole and even the general public.

For the individual:

  • Providing wider recognition outside of your own specific discipline;
  • Enabling you to demonstrate to employers and other professionals your commitment to a high level of competence and continuing professional development; and
  • Demonstrating the breadth of your career across the field of science.

For the employer:

  • Providing assurance of the capability and commitment of employees; and
  • Providing a platform for interdisciplinary networking through demonstrating a commitment to high-level professionalism.

For the profession:

  • Setting the same high standard for all professional scientists, irrespective of their sector;
  • Ensuring all CSci are participating in Continuous Professional Development; and
  • Promoting interdisciplinary networking amongst professional scientists.

For the public:

  • Creating a single recognisable standard across (and beyond) the science professions; and
  • Improving the public’s trust of scientists through their demonstration of commitment to professional standards.
