I did hear straight from my EC that assessment day date was what they planned to use as of some time late last year. Most of those ACO/JBAC candidates have valid OSB recommendations so it makes sense for them to be at the front of the line. OSBs are probably a little more taxing to run than assessment days.
However, I'm a bit wary that I may have slipped through the cracks again which incidentally also happened with my dossier for flight screening. Just out of curiosity did you guys receive offers from your EC, the ACMC or just some generic DFR contact?
