Registered Scientists can be found in a huge variety of scientific and higher technical roles. They apply their skills and knowledge whilst working autonomously and have the ability to resolve problems and identify, review and select appropriate techniques, procedures and methods.

Once registered, you must maintain your status through meeting continuing professional development (CPD) requirements each year. As you progress in your career and gain more responsibility and experience, you may want to apply for Chartered Scientist.
