Postgraduate Diploma in GD&T and 2R Assembly Dimensional Control — studying from South Africa
Two-wheeler transport is significant in South Africa, both for commuting and for delivery services, and the motorcycle and scooter market has grown steadily. Local assembly and distribution of motorcycles and scooters are supported by importers and manufacturers, and the sector interacts with road safety regulation and licensing. Engineers working on two-wheelers focus on chassis design, braking systems, emissions and rider safety. Growing interest in electric scooters and light mobility is also shaping demand.
Fees for South Africa: R 27 900 (South African rand), with instalments and employer sponsorship available.

Questions from South Africa
Will a SEIUM qualification be recognised by the professional bodies in South Africa for this area?
SEIUM qualifications are private and not accredited by any South African body, so they are not official state degrees. Professional engineering registration runs through ECSA, and motorcycle-related standards and testing involve bodies such as the SABS. Whether a SEIUM qualification is recognised is for employers or the relevant body to decide, so check before enrolling.
How might this qualification be used by employers in South Africa in the two-wheeler sector?
Motorcycle manufacturers, importers, dealers and component suppliers may value engineering depth in vehicle dynamics, powertrains or design. A private qualification can add to your profile, but it does not carry official status, so its impact depends on employer preference and your existing experience. Speak to potential employers to understand their view.
Can I study this programme alongside full-time work from South Africa, and is there a time zone or language issue?
The programme is fully online and taught in English, so you can study from South Africa without a student visa. Master's programmes require 1,900 hours, postgraduate diplomas 800 hours and specialist courses 300 hours, with an assigned technical tutor. Fees can be paid in instalments and employer sponsorship is possible. Ask SEIUM about time-zone expectations and weekly workload before enrolling.

How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are 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 PC-DMIS, ZEISS CALYPSO, PolyWorks Inspector, 3DCS Variation Analyst, Minitab, in free, academic or evaluation versions. Tests are based on real measurement procedures for a welded frame using a laser tracker, fairing inspection with a structured light scanner, and R&R studies of critical dimensions on the assembly line. Assessment is continuous per module, plus the final integrative project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
