The SRG1157 is a skill test form not for revalidation by experience. If we are testing a candidate and they need another rating signed off by experience then we can use the form to do it at the same time. An example would be where I was renewing the MEP for a candidate and they want the SEP revalidating by experience then I can incorporate into a single form. However the SRG1157 is not to be used where revalidating by experience solely according to the CAA.
