If I study an IIE Bachelor of Engineering Degree, will I be able to register as a Professional Engineer?
Yes. Once you complete an IIE Bachelor of Engineering degree, you will have completed the first step required to register as a professional engineer. After graduation you will need to get experience working in industry in the discipline of your degree and then you will need to apply to the Engineering Council of South Africa (ECSA) for registration as a Professional Engineer. You can also register as a Candidate Engineer as soon as you complete your degree.
There is a detailed description of why you should register and how to do so on the ECSA website.
