For all those wanting to become a Social Security Administration vocational expert, part of your additional research is to actually understand the textbooks that are available in the field. Unlike a true vocational education or collegiate preparation, there arent many courses out there (other than the VELaunchpad!) that set you up with this information.
The primary source for everything right now as an SSAVE is the Dictionary of Occupational titles. While this book has been out of print since 1991, its still possible to get your hands on a copy of it. Simultaneously, most of the functions of the SSAVEs are going digital. However, having a hard copy of this document will make it even easier for you to conduct deep analysis prior to any type of testimony particularly when conducting claimant work history analysis. Just like everything else, Amazon has it& check it out here.
