Formal training, Yes, by the KA training dept. The blind leading the blind!
What required standard? Very difficult to have Standards when TIREs are allowed to make up whatever scenarios they feel like on the day.
They then publish their reports for all trainers to see 2-4 days later and it is your word against theirs.
You want standards, you need to have set scenarios, all command sims should be video taped and the report should be completed on the day and signed by both parties.
