Registration as a scientist provides status and professional recognition for those working in scientific and higher roles. Registered scientists represent the best professional scientists working worldwide. Leading teams and departments, use their specialist knowledge and broader scientific understanding to develop and improve the application of science and technology. Scientist status registration with SR21 reflects the wide variety of sciences and their practice, recognizing high levels of skill and experience, independent of discipline. Once registered, you must maintain your status by meeting continuing professional development (CPD) requirements. As an applicant, you need to demonstrate your competence across various areas by providing examples from your working life, usually within the last five years. You will also need to provide professional references that can vouch for your knowledge and experience. They are then assessed, on paper and in a face-to-face interview.
