ExploreAbout this exam
The Institution of Engineers, Sri Lanka (IESL) is the apex body of engineering professionals in the country and awards credentials such as the Chartered Engineer - CEng (SL) and AMIE (SL), which enable a member to practise as a licensed engineer in Sri Lanka. IESL was incorporated in 1968 by Parliament Act No.17 and describes itself as the largest engineers' organisation in Sri Lanka with over 25,000 members. Within IESL's structure, the Mechanical Engineering Sectional Committee sits alongside the other disciplinary sectional committees, and the Institution publishes Professional Review (PR) rules and PR details for the CDP and Mentor route, which are the framework a mechanical candidate should read before preparing. This page is an independent study resource for candidates working toward the IESL Professional Review in mechanical engineering; it is not affiliated with, endorsed by, or operated by IESL, and it does not reproduce IESL's own documents. Because IESL does not publish the examination format, duration, pass mark, fees or retake rules on the public pages summarised here, this page does not state them - treat any figure you see elsewhere with caution and confirm it directly with the IESL secretariat. Preparation should centre on the official PR rules, your CDP record and mentor guidance, and on defending real mechanical engineering decisions from your own training and experience.
What you'll study
About IESL Part II Mechanical preparation
What exactly is the IESL Part II Mechanical examination?
IESL awards the Chartered Engineer - CEng (SL) credential, and the Professional Review (PR) is the route it publishes for candidates moving from Associate to Chartered status. IESL's public pages describe PR rules and PR details for the CDP and Mentor route but do not publish a separate mechanical-specific syllabus, so confirm the exact requirement for your route with the IESL secretariat.
Who should sit it?
Engineers aiming at Chartered status through IESL, typically Associate Members who have completed the required continuing professional development and mentor process. IESL publishes separate PR details for the CDP and Mentor route and lists recognised training organisations, so check that your training and CDP record fit the route you intend to use before you apply.
What format does the assessment take?
IESL's public pages do not state the format, duration or structure of the Professional Review, and this page will not guess. The defensible answer is to read the current PR rules and PR details for the CDP and Mentor route on iesl.lk and to confirm arrangements with the secretariat, since the published rules govern what you will actually face.
How hard is it, and what trips candidates up?
The common failure mode is a thin, generic record: CDP entries logged without reflection, and project narratives that describe what the team did rather than the engineering decisions you personally made and can defend. Reviewers probe depth, so prepare a small number of projects thoroughly - your calculations, alternatives rejected, codes applied, and outcomes - rather than many shallow ones.
Is there a fixed pass mark or a limited number of attempts?
IESL does not publish a pass mark, attempt limit or retake policy on the pages summarised here, so none is stated on this page. Candidates should request the current rules in writing from the IESL secretariat before applying, and keep copies of any guidance you receive, because undocumented assumptions about retakes are a frequent source of avoidable stress.
How much time should I allow for preparation?
No official preparation period is published. Practically, work backwards from your CDP and mentor requirements: those records take months to build properly, not weeks, so start logging reflective entries early. Leave focused time before the review to rehearse defending your chosen projects aloud, including the numbers, the standards you applied and what you would do differently.
In what order should I study?
Start with the governing documents, not textbooks: the PR rules and the PR details for the CDP and Mentor route. Then audit your own CDP record and mentor sign-offs for gaps. Only after that should you revise technical content, targeting the mechanical areas your submitted projects actually rely on, so your revision supports the case you will present.
Does this page come from IESL?
No. This is independent study material written for candidates searching this exam. It is not affiliated with, endorsed by or approved by the Institution of Engineers, Sri Lanka, and it does not reproduce IESL question papers or guidance documents. Always treat iesl.lk and the IESL secretariat as the authoritative source for rules, dates and fees.
