Every Course Evidence article starts with an evidence label. Unknowns stay visible instead of being converted into recommendations.
Evidence profiles
- E1 — source-led research: current public sources, dated checks, visible limitations, and no direct-use claim.
- E1+E2: E1 plus controlled direct evaluation using a documented workflow.
- E1+E3: E1 plus original research using a reproducible method.
- E1+E2+E3: direct evaluation and original research are both complete.
What we check
Depending on the page type, we may check curriculum structure, prerequisites, access limits, workspace requirements, cancellation or renewal terms, official objectives, provider rules, and public support documentation.
Limits
Course catalogs, subscription terms, labs, and certification objectives can change. Articles include checked dates and review triggers where relevant. If a page has not been directly tested, it should not be read as a hands-on review.
