I have done both RTITB, LANTRA and In House training and find RTITB with it's 3 year refresher to be of a good enough standard. Also within Logistics & Warehousing RTITB is the one qualification that most companies seek.

The military, more so the RAF are now using RTITB to train with.
It is seen as a professional qualification that can be transferable from service life to a civilian one.
