One correction, the BGA must have changed the policy since I last
checked -- its post-solo pilots only who are allowed to do a DI.

BGA Instructor Manual, Section 8-31, PDF Page 4, column 2:

Only 'licensed pilots' can DI club gliders, so this bars pre-solo
pilots from doing them.

Even so, pre-solo pilots are involved heavily in the DI process as it
really is a good way to familiarise students with gliders, and frosty
winter starts from being totally dire for the local solo club-flying
members.


Similar in Oz. There's a small book called a Maintenance Release in the glider, that takes the place of carrying around the full aircraft logbook and AFM. Requires a signature in it before first flight of the day, or after rigging. There's training for the Daily Inspection (videos talked about earlier), and a signoff, but its not a big process to do so. DI rated people here in Oz are also expected to be able to do additional duties beyond preflight, such as double inspections during annual inspections etc.
