The single, overriding intent and justification for the legal regulation of any profession—be it medicine, law, engineering, or applied science technology—is the protection of the public interest. While admitting people to the profession and differentiating from unregulated trades are administrative outcomes of regulation, they are not the reason regulation exists. The government grants self-regulatory powers through statutes like the Engineering and Geoscience Professions Act (EGPA) because the work performed by these professionals involves highly complex technical knowledge that the general public cannot easily evaluate. Incompetent, negligent, or unethical practice in engineering technology can lead to catastrophic failures, financial ruin, environmental disasters, or loss of life. By regulating the profession through bodies like ASET, strict standards for education, experience, continuous development, and ethical conduct are enforced. This system ensures that the public can trust that individuals holding professional designations have the competency and ethical integrity necessary to perform their work safely and reliably.
