A March 2007 "Review of the EPSRC Engineering Doctorate Centres" noted that since 1992, some 1230 research engineers had been enrolled, sponsored by over 510 different companies (28 had sponsored at least six REs), at 22 centres based at 14 universities (some jointly run by several collaborating universities). The panel remained convinced of the value and performance of the EngD scheme, and made six key recommendations including clearer brand definition, academic study of the longer-term impacts of the scheme, promotion of the scheme to potential new sponsors, business sectors and REs, work with the Engineering Council UK to develop a career path for REs to Chartered Engineer status, creation of a virtual "EngD Academy", and increased resources for the scheme.
