Becoming a Chartered Scientist (CSci)

Chartered Scientists (CSci) represent the best professional scientists working in the UK and abroad. They demonstrate effective leadership, using their specialist knowledge and broader scientific understanding to develop and improve the application of science and technology by scoping, planning and managing multifaceted projects.

Chartership as a scientist reflects the wide variety of sciences and their practice, recognising high levels of skill and experience, independent of discipline.

Once registered, you must maintain your status through meeting continuing professional development (CPD) requirements each year.

Why become a Chartered Scientist?

Professional registration as a Chartered Scientist provides independent recognition of your achieving and maintaining the exacting standards required to join the global community of professional scientists. Benefits include:

  • Be publicly recognised for your professional excellence
  • Increase your confidence and skill
  • Demonstrate your ethical credentials
  • Improve your chances of promotion
  • Become a leader within your field
  • Join a worldwide community of cross-disciplinary scientists

Who can join?

The application process for becoming a Chartered Scientist requires master’s degree (Level 7) thinking, demonstrated either through achievement of a relevant master’s degree or through the submission of written work deemed to be at an equivalent level by the registration assessors.

If you do not hold a relevant master's degree (Level 7), you can apply for CSci through CIWEM’s Work Based Learning route. This provides a means of enabling experienced applicants who lack the exemplifying academic qualifications to demonstrate the knowledge and understanding which they have acquired through their working experience against the QAA qualification descriptor for Masters level. Guidance on completing the Work Based Learning route can be downloaded here. When you are ready to complete the application, you will also need to submit the 'Grade 7 Work Based Learning Statement Form' which can be downloaded here.
