SNCO Promotion Boards

I have recently completed my matrix for FS and duly submitted to my boss, however not really sure what to expect on the actual board - does anyone have any experience of this? I wondered if it’s similar to a Sgt’s board in terms of knowledge check on RAF etc.

Maybe one of these can help:

Wing SNCO Board

SNCO Board

Going for snco board

Snco selection boards

Snco (atc) promotion boards

Adult snco process. Advice and guidance needed
