Introduction The Institution of Engineers, Sri Lanka (IESL) which is the premier professional body for engineers in Sri Lanka has gained reputation for its excellence in providing engineering education in the country. Its part-time engineering course which is recognized as an equivalent to engineering degrees offered by state universities in the country fulfills the academic qualifications required to become a fully-fledged engineer. The qualification is well recognized to gain employment as a qualified engineer, both in the state and the private sector. Thus the IESL Engineering Course has become a top choice for those students who wish to pursue engineering as a professional career but deprived of gaining entry to state universities due to various reasons. The course consists of three levels, Certificate, Advanced Diploma and the Graduate Diploma. It is specially designed to facilitate lateral entry at the start of levels 1 and 2 and multiple exits, at the end of each level. The curriculum has also been revised recently to improve its’ quality, relevance and effectiveness and also to promote outcome-based education, gearing the students to be successful in a dynamic and challenging work environment. The students have the choice of selecting several fields of specialization from civil, electrical, mechanical and electronic, communication and computer engineering. A major advantage in following the course is the students who satisfactorily complete the course are eligible to become Associate Members of the IESL, a professional qualification well recognized by the state and the private sector alike, paving their way to a successful career as an Engineer. IESL College of Engineering (Pvt.) Ltd: In 2011, The IESL College of Engineering (pvt) Ltd., a company fully-owned by the IESL, was established with the intention of conducting the Engineering Course in a more efficient and effective manner. The IESL College of Engineering (IESLCE) is committed to provide the students high quality education in major fields of engineering while fostering innovation and creativity among them. It is determined to become the best choice for tertiary education in engineering for those who miss the opportunity of entering state universities and thereby 1
becoming a key institute producing quality engineers for the state and private sector.
COURSE STRUCTURE: Certificate level Engineering Certificate Stage 1 – One Year Engineering Certificate Stage 2 – One Year On successful completion of the Certificate level Stages 1 and 2, students are eligible to receive IESL Engineering Certificate.
Advanced Diploma Level Advanced Diploma Stage 1 – One Year Advanced Diploma Stage 2 – One Year on successful completion of the Advanced Diploma Stages 1 and 2, students are eligible to receive IESL Engineering Advanced Diploma.
Graduate Diploma Level Graduate Diploma – One year On successful completion of the Graduate Diploma students will be awarded the IESL Engineering Graduate Diploma and also be eligible to obtain the Associate Membership of the IESL. The course is designed to provide a good balance between theoretical knowledge and practical skills. The theory classes of the course are conducted at the IESL headquarters in Colombo, during the weekends, to allow students who are already employed, to follow the classes at ease. The practical sessions are conducted at the University of Moratuwa and the Open University of Sri Lanka. The medium of instruction is English.
