“My development journey towards Chartered Scientist has been one the best experiences in my career, it really pushed me to widen my knowledge of the water industry beyond Scientific Services which is a real benefit to my role. Having started as a modern apprentice and going on this journey of professional registration has been invaluable in helping me to progress in my career to where I am now and would definitely recommend.“
Angela Dignan CSci, Team Manager (Scientific Services), Scottish Water
Who can become a CSci?
CSci Applicants need to demonstrate their competence across five areas by providing examples from their working life, usually within the last five years, that illustrate how they have met each standard. This is then assessed either online or in a face to face interview.
CSci applicants must have EITHER a Level 7 (Master’s degree or higher) qualification within a scientific discipline OR the equivalent learning and achievement. If you do not have any relevant qualifications to include then please ensure you complete the CSci equivalency section of the application form. The Science Council have produced some guidance to help applicants with the completion of this via the CSci Equivalence guidance.
