Who runs this site
STE Guide is run by an independent team of technical writers who use Simplified Technical English in their work.
Our purpose
We want to make STE easier to understand and to learn. We explain the standard in simple words, give free practice tools, and send readers to the official ASD STE 100 PDF. We do not sell training or certificates.
