How TRADECAIRN works
Recommendations should still make sense if no commission exists.
TRADECAIRN is built to be useful first. We separate editorial recommendations, official sources, and retailer relationships so users can see why something is recommended and where the information came from.
Field Tested
Used when a tool, category, or workflow is grounded in real field experience and practical trade use.
Trade Recommended
Used when a product or approach is widely respected for professional work even when we are not presenting it as a single universal best choice.
Manufacturer Verified
Specifications, compatibility, ratings, or model details are checked against manufacturer information where that matters to the recommendation.
Official licensing information stays separate
State boards, government agencies, code authorities, OSHA, NFPA, apprenticeship agencies, and other official sources are linked as normal editorial sources. We do not turn official authority links into affiliate links.
Affiliate links are disclosed
When TRADECAIRN is approved for a retailer or training-provider affiliate program, the affiliate relationship is disclosed. We keep the underlying recommendation separate so retailers can change without rewriting the guidance.
We distinguish training, certification, and licensing
A training completion card, a professional certification, and a government-issued license are not the same thing. TRADECAIRN labels them separately and points users back to the issuing authority for current requirements.
We expect information to change
Licensing rules, exam vendors, NEC editions, fees, reciprocity agreements, product models, and training programs can all change. That is why our state and credential pages identify official sources and verification dates wherever practical.
