Make sure they can actually find/source an examiner. (Sounds silly, but some schools really struggle to get one in the right place at the right time).
Difficult if UK JAA CPL testing as the CAA now organises the testing.
Which means now you have two agencies:
- Your school who provides the training.
- The CAA who provides the testing and availability of examiners.
Best thought of separately if you want to make the system work for you.
It is not uncommon at times to wait around 5 days for CPL or IR testing.
