First, companies must be approved to be Verifier or Trainer Bodies.  Once a company is deemed eligible, they are provide a link to an application for individual verifiers.  After that, it is a two step process. You must first fill out an application and pay the application fee. If you are deemed eligible, then you go to step two. Step two is the training. You would be provided a link to a specific training (a learning plan) at which point you will enroll and pay for the training.  After successful completion of training, you are considered approved for the specific service.
