The systems was supposed to be introduced in order to allow firefighters who suffer from exam nerves, dyslexia and many other conditions to be able to get promoted by proving that they are the right people for the job, what has happened instead is that the system is now more able to be abused than the old system. I know of a senior officer who was doing interviews and gave mock interviews to candidates in order to train his interview skills. Funnily enough, every single person from his cronies and hangers on who had a mock interview passed the adc. When my mate asked if he could have a mock interview with this particular senior officer, he was told that he should "Just get on with it, if you're good enough you'll pass anyway, if not you won't" Guess what, he never passed.
Same **** , different process (only now open to even more abuse)
