How does this Certification relate to Workshop Levels 1, 2 and 3?
They are not related at all. You will find that most of the content in these workshops is covered in the EFT Foundational Library. Since that structure was introduced, EFT has developed even further and the new Certification Program will represent EFT knowledge on a much grander scale. Further, the Certifications offered at those workshops are not official EFT Certifications, but have been offered by the individual workshop presenter or organization. Some organizations, like the AAMET, have developed their own Certification programs based on those Levels, so you will need to contact them for more information.
