moku and skyman - BOTH WRONG.
The R/T is required before taking the CPL skill test - not the training - the FLIGHT TEST.
skyman - no, it's not a joke - you just treat it like one.
gabu - the R/T practical must be done with an R/T examiner - not an instructor.
Short answer - you need to pass the R/T before being alloowed to take the skill test for the CPL (unless exempt, of course).
