About this exam

The Institution of Engineers, Sri Lanka (IESL) is described on its own website as "The apex body of engineering professionals in Sri Lanka," incorporated in 1968 by Parliament Act No. 17, with over 25,000 members. IESL states that it awards credentials such as Chartered Engineer – CEng (SL) and AMIE (SL) enabling a person to practise as a licensed engineer in the country, and that it is the sole credentialing authority for engineering degrees offered in Sri Lanka, including for the internationally recognised Washington Accord. The Part I Examination is known in IESL's own announcements as the "B Paper Examination"; IESL publishes results of sittings under that name, for example a passed candidates list for the March 2026 sitting. Candidates reach this examination through IESL's Education & Evaluation pathway, which lists entry requirements, academic qualification assessment and qualifying examinations, alongside accredited and recognised degrees. The examination is broad: IESL's sectional committees cover Agriculture and Plantation Engineering, Building Services Engineering, Civil Engineering, Chemical & Process Engineering, Electrical, Electronics & Telecommunication Engineering, IT and Communication Engineering, and Mechanical Engineering. Preparation should therefore combine a working command of your own discipline with enough breadth across the other branches to handle general engineering questions. Use IESL's published entry requirements and qualifying examination pages to confirm eligibility, and past-paper practice under timed conditions to build speed.

What you'll study

Common questions

About IESL Part I preparation

What exactly is the IESL Part I Examination?

IESL's public announcements refer to this sitting as the "B Paper Examination" and publish passed candidates lists under that name. It forms part of IESL's Education & Evaluation pathway, which lists entry requirements, academic qualification assessment and qualifying examinations. Check IESL's own Education & Evaluation pages for the authoritative scope and eligibility rules.

Who should sit it?

Candidates working through IESL's membership and chartering pathway who need to satisfy the qualifying examination stage. IESL sets entry requirements and assesses academic qualifications separately, so confirm your route - standard, direct or MRA - before you plan study time. If your degree is accredited or recognised by IESL, ask whether the examination applies to you at all.

What does the exam cover?

Expect general engineering breadth plus depth in your own branch. IESL's sectional committees span Agriculture and Plantation Engineering, Building Services, Civil, Chemical & Process, Electrical/Electronics & Telecommunication, IT and Communication, and Mechanical Engineering. Prepare your strongest discipline thoroughly, then build enough familiarity with the others to attempt general questions confidently.

How long is the exam and how many questions?

Not stated in the source material available here, so treat any figure you hear as unverified. Confirm paper structure, duration and marks directly with IESL before your sitting. Plan practice sessions around the confirmed format rather than guessing; a timed mock under the real structure is the most reliable way to calibrate your speed.

What is the pass mark?

Not published in the source material available here. IESL does not state a passing score on the page consulted. Ask the IESL secretariat or check the qualifying examinations documentation for the marking scheme. Until you have a confirmed figure, target thorough coverage rather than a minimum threshold.

Can I retake it if I fail?

The retake policy is not stated in the source material available here. IESL publishes results per sitting, which implies periodic examination cycles, but the conditions for re-sitting are not confirmed. Contact the IESL secretariat at [email protected] to confirm eligibility, waiting periods and any fees before relying on a retake plan.

How much does it cost?

Fees are not stated in the source material available here. IESL maintains separate pages for membership enrolment fees and membership fees and payment methods, but examination-specific charges are not confirmed. Request the current fee schedule from the secretariat in writing so you have a dated record.

In what order should I study?

Start with your own discipline to secure the marks you can bank reliably, then add breadth across the other six branches, prioritising topics that appear in general engineering questions. Finish with timed practice and review of weak areas. Breadth-first study sounds efficient but usually leaves you weak everywhere; depth first gives you a stable base.

What are the most common failure modes?

Running out of time because practice was untimed; answering only from your own specialism and leaving general questions untouched; and misreading eligibility or application deadlines. IESL publishes announcements and event deadlines on its site, so track the application window early. Confirm your qualification assessment is complete well before the sitting.
