The bible of licence conversions CAP804 has been updated such that if you are a QHI or QFI and broad brush at least a B1, if you satisfy the tedious requirements to prove you can instruct (yet another flight test) you go straight to unrestricted instructional status.
Pity QGIs weren't included. Some of us are A2 or A2* with four-figure hours and a lot of real solo sending on what in class-rating terms is a TMG but receive no exemption or credit at all.
