Registered Scientist (RSci)

There are thousands of scientists in the water industry, working in a wide variety of roles for water companies, regulators and across the supply chain. If you are one of them, and are interested in gaining recognition for your high levels of professionalism and scientific competence, then why not consider becoming a Registered Scientist through the Institute of Water?

Who can become a Registered Scientist?

Registered Scientist registration is open to anyone who can demonstrate the competencies required by the Science Council, and who is willing to abide by their Code of Conduct. The competencies sit inside the following overarching statements:

  • Identify and use relevant scientific understanding, methods and skills to address broadly-defined, complex problems
  • Exercise personal responsibility in planning and implementing tasks
  • Demonstrate effective communication and interpersonal skills
  • Apply appropriate theoretical and practical methods
  • Demonstrate a personal commitment to professional standards

Each of these is broken down into specific attributes which all Registered Scientists are expected to have. Before you consider applying for RSci, you should be familiar with the competencies required. You can view the competencies here.

RSci is a competence-based award, meaning that you can achieve RSci through your experience alone but, if you do hold formal qualifications, they could count as evidence against some or all of the competencies that need to be demonstrated.

How can I become a Registered Scientist?

Consider the standards required for registration and discuss these with your employer or with another Registered or Chartered Scientist. Read through the application form, the Science Council’s report tips, the Competence Report guide and, once you are ready to apply, the process is simple and can be seen in this flowchart. The flowchart should be read in conjunction with the applicant’s short guide
