Institution of Incorporated Engineers

The Institution of Incorporated Engineers (IIE) was a multidisciplinary engineering institution in the United Kingdom. In 2006 it merged with the Institution of Electrical Engineers (IEE) to form the Institution of Engineering and Technology (IET). Before the merger the IIE had approximately 40,000 members. The IET is now the second largest engineering society in the world next to the IEEE. The IET has the authority to establish professional registration of engineers (Chartered Engineer or Incorporated Engineer) through the Engineering Council. The IEEE does not have the authority to replicate the registration process in its complementary environment.
