Registered Scientist (RSci) is a professional qualification in the United Kingdom that was introduced in 2012 as an extension to the Science Council's existing professional registers. This register extends the framework to allow professional recognition for higher technical roles. Holders of this qualification can use the post-nominal letters RSci. The Registered Scientist and Registered Science Technician (RSciTech), which was introduced at the same time, were developed with the support of the Gatsby Charitable Foundation.
