There is no national license for this trade, and no certificate worth having is handed out for watching videos. WFR certification is a judgment of your hands, made in person, against the same standard used at the WFR Family Reunions.
Your own hands, judged level by level. Each level is a standard you have to meet on real glass, in front of the people qualified to judge it. Earn the first level at a trainer shop or a Reunion, then climb.
One car, two installers, one clock. The Team Player certificate is binary — the pair earns it together or not at all — because that is how the work actually gets done in a shop.
There is a written test, and it matters — but passing it does not certify anybody. The certification is the judged install. That is deliberate: customers trust the mark because it was earned on glass, not on paper.
No. Manufacturer certifications cover a brand's own film and programs. WFR certification judges the installer's hands against the WFR standard — the same standard used at the WFR Family Reunions — regardless of which film is on the glass.
No. A written test exists, but a test is not the certification. Singles levels and the Team Player certificate are earned in person — at a WFR trainer shop or at a WFR Family Reunion.
Singles is individual certification in levels, earned as your hands prove each standard. Teams is the Team Player certificate: a pair earns it together, on a full car, under the clock — the way real shop work actually happens.
Training and certification are arranged through the trainer shops, and each shop sets its own schedule and pricing. Ask the shop in your market.
Manufacturer certifications (3M, LLumar/Eastman, Solar Gard) and association accreditations (IWFA) also exist — the training resource map lays them all out in one place so you can compare before you spend.
