Who we are
Engineers who built this for our own companies first
We are engineers who run engineering, construction and energy companies. AI Work School started from what our own teams needed: practice for the certification exams in our fields, short courses for new kinds of work such as data centers, automation and carbon, and safe AI habits for the office.
We build the material the way we build projects: calculations checked, sources named and mistakes fixed in public. Then we opened it to everyone.
How we build it
- Every exam question is original. We never use or sell recalled exam items.
- Every calculation is recomputed by code, and each question is solved a second time independently.
- Paid questions open to buyers only after a qualified reviewer signs them off. Reviewer names are published as they sign on.
- Every fix is logged in public. See the quality page
