CRM/HUET Currency
Generaly, the currency period is detailed by the provider of the course as this will usually come from the body that approves their courses. (i.e. a Government body that may approve or certify the course provider to conduct such courses). Sometimes these courses are required to be re-approved every (say) 2 or 3 years, hence the currency period.
Secondly, the currency period may be dictated by the Authority (i.e. RFS) that may or may not say that the course has to be conducted no more than X years ago or be current.
Thirdly, a certain currency maybe lsited in the operators operations manual.
Interestingly, in Aus, CASA does not stipulate a currency period for "underwater escape training"; only that it must have been undertaken. This requirement is actually only for Night MPT operations though.
A dam good course though, the HUET, and hopefully you will never have to use it!
