I've had a search for this but haven't seen any results. Does anyone know if there is a limit to the number of times you can sit the OTDPQ? I'm aware that I don't think there is an outright pass/fail per se but that it is used in conjunction with a DMI. I'm also aware that it's not part of the mandatory assessments but I don't know if the OPC/TOCs have any test-specific rules on this one.
