The CAA form is a record of solo send offs supervised by a FI at least and countersigned by CFI or similar. It relies on trust and is thus open to abuse. However, we are mostly "good eggs" and we do supervise our new FI and help the system by ensuring honest and true reports to CAA. SOP's will normally be obvious even if not written down. So it is not really a big deal but it can take a long time to get 25 solo send offs in some RTF/FTOs.
