My full name is showing, how can I stop it?
All assessors are trained to a standard set by the DWP in Disability Assessment, as a result you cannot assume that person who assessed you was not qualified to do so just because they do not have a background in or training relevant to your conditions..
You will need to show that they lacked experience in your conditions and that as a direct result of this they failed to take account of evidence that an HCP who was trained in that area or medicine would have taken into account AND that this evidence was relevant to the criteria of the benefit you were attempting to claim such that you failed to score points that you might otherwise have expected to receive.
