The Institution of Engineers, Singapore was formally established on July 1966 as the national society of engineers in Singapore. IES is the premier engineering Institution in Singapore and is often called upon by the Government to provide feedback on professional engineering matters.

IES is well represented among the faculty members of the major engineering institutions of higher learning in Singapore. Through close collaboration with the local universities and polytechnics, IES organizes courses, seminars and talks for engineers and IES members to advance the continuous development of engineers.

The Institution maintains close links with professional organizations of engineers regionally and throughout the world. These include organisations in Australia, China, Japan, United Kingdom and the United States. The Institution also represents Singapore in the World Federation of Engineering Organisations (WFEO), ASEAN Federation of Engineering Organisations (AFEO) and the Federation of Engineering Institutions of Asia and the Pacific (FEIAP) in promoting goodwill and fellowship among all engineers in the region and internationally.

Through its Engineering Accreditation Board (EAB), IES obtained full signatory status in the Washington Accord (WA) in June 2006. The entry grants IES the authority to represent Singapore, the first country within the ASEAN region which has obtained full signatory status in the WA, to vet education systems under the WA mutual recognition framework.

To raise the technical competencies of engineers in Singapore and promote engineering to the community, IES has introduced the Chartered Engineer Programme, World Engineers Summit and National Engineers Day. IES will not rest on its laurels and will seek to bring the engineering profession greater recognition and raise the status of engineers both locally and internationally through closer collaboration with its stakeholders and contributions to society.

IES is well-represented in the engineering domain by maintaining close links with professional organisations of engineers to promote goodwill and fellowship among fellow engineers. IES presence is felt locally, regionally and internationally.
