There is a national standard pass Mark. But each TOC sets their own perimeters and if it's higher than the set national standard it's then classed at an Enhanced pass requirement. For example, I pass chiltern and WMT at enhanced for stage 1, but, when I went for the Virgin Apprentice Scheme I was asked to re-do the GBT only as Virgin set a higher standard pass Mark than chiltern and WMT. I turned down that opportunity as I'd already spent a life with OPC and didn't want to fail for Virgin as that's classed as a life because I would have attempted the OPC process twice. Hope this helps. Btw is anyone else on stage 2 tests on Tuesday 4th Sept?. I'm stopping over night before.
