The Newest Member of ACECC

Incorporated in 1968 by the Parliament Act No.17, the Institution of Engineers Sri Lanka (IESL) is the largest engineers’ organization in Sri Lanka with over 20,000 members. About two-thirds of them are civil engineers. IESL is actively engaged in providing engineering perspectives on issues of national significance to the government and the general public. 

Vision Statement

Be amongst the leading professional institutions in engineering and technology in the world.

Mission Statement

To be the apex national body of engineers in Sri Lanka which ensures internationally recognized and locally relevant standards in the professional practice and education in engineering, while actively supporting national development and diligently serving its members and the society at large.


The Institution of Engineers, Sri Lanka (IESL) established in 1956 was the successor to the then Engineering Association of Ceylon which was founded in 1906 at Anuradhapura by a few dedicated engineers serving in the public sector, with the objective of providing general advancement of science and practice of engineering in all disciplines concerned according to rules agreed to by its members. In 1968, the Institution of Engineers, Sri Lanka was made an incorporated body of the Government by an act of parliament. It represents the interests of the engineering profession and the general public its members serve.

The activities of IESL have become broader and diversified with time, and at present it has a membership of about 22,000 engineering professionals of all branches of engineering serving in all parts of Sri Lanka and abroad. Civil engineering has the majority of members.

One of the key functions of IESL is to ensure the quality standards of engineering professionals practicing in Sri Lanka, by conducting a Professional Review of suitably qualified members for the status of ‘Chartered Engineer’ and ‘International Professional Engineer’.

The IESL conducts long and short-term Continuing Professional Development programs, seminars, learned lectures, and orations and also recognizes organizations that provide training for the charter candidates after a rigorous evaluation process. It also recognizes academic institutions that provide engineering education for the different levels of membership of the IESL and is the accreditation body for engineering degrees in Sri Lanka. Qualifications of graduates of institutions that are not accredited or recognized by the IESL are evaluated on a case by case basis, for acceptance for membership.
