Methodology, software & labs

How you'll learn

100% online training on the SEIUM campus, with downloadable material, recorded classes and a dedicated technical tutor. No fixed timetables: students progress at their own pace within the intake, which makes it possible to combine study with work.

Each module combines theory, guided reading of the original standard and applied exercises. The working software is Mitutoyo SURFPAK, MountainsMap, advanced Excel, Minitab, in free, academic or evaluation versions. Tests are studied using real measurement procedures with a stylus profilometer, control of cylinder honing, and comparison with reference specimens. Assessment is continuous by module plus the final integrating project.

Accreditable laboratories(EN ISO/IEC 17025) with a rotor rig, EMC/Lightning pre-compliance, HIL/SIL, vibration/acoustics.
Evidence-driven Master's Thesis:safety case, test plan, compliance dossier and operational limits.
Industry mentoring:lecturers with experience in training, , eVTOL/UAM and flight test.
Flexible delivery(hybrid/online), international cohorts and support from SEIUM Career Services.
Ethics and safety:a safety-by-design approach, with OT cyber-security, DIH and compliance as pillars.

FAQ

Frequently asked questions

The programme comprises 300 hours in total, spread over 3 to 5 months. That is an average of 10 to 15 hours per week, compatible with a full-time job.

You will work with Mitutoyo SURFPAK, MountainsMap, advanced Excel and Minitab. Free, academic or evaluation versions are used, and the tutor will indicate the free alternative where one exists.

A SEIUM own diploma upon passing the continuous assessment and the integrating project. It is in-house training, not an official title from the Ministry.

Yes. Modules passed in a course or postgraduate diploma in the same area are credited towards the advanced programme. Check the credit transfer policy when you enrol.
