Every AI model you have heard of was trained on data that human beings labeled by hand. That work is real, it is skilled, and this course teaches you to do it to a professional standard — and measures how well you do it.
It also tells you the truth about the industry. Most well-known crowd platforms are closed to Nigeria, the simple end of the work is shrinking, and independent research across 776 workers found 31% reporting non-payment. You get the evidence, with sources, in Module 1.
What is genuinely open: the skill transfers to quality assurance, research operations and compliance; Nigerian languages are badly under-supplied in training data; and the growth is in judging model output rather than drawing boxes. Your certificate reports a measured quality score, not just a pass.
