Questions from Singapore
What language are the programmes taught in?
All programmes are taught in English.
Are SEIUM qualifications official degrees in Singapore?
No. SEIUM qualifications are private qualifications awarded by SEIUM Institute and are not official state degrees. Learners should check with the relevant professional bodies in Singapore about how any qualification is treated for their specific purpose.

How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: you progress at your own pace within each intake, so you can combine the programme with your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MATLAB, Python, VABS, MSC Nastran, CAMRAD II, in free, academic or evaluation versions. Testing is studied on real procedures for impact modal testing, scale rotors in wind tunnels and full-scale fatigue tests. Assessment is continuous, module by module, plus the final integrated project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
