Hi Just thought I'd share my lads trip to joining up as a ETWE in light of his colour blindness. In January he had his colour blindness test and was told he was CP4. I found this online: CP1 & CP2 - Good colour vision, able to pass Ishihara test (not sure of the difference between CP1 and CP2) CP3 - Failed Ishihara test but able to pass holmes-wright lantern test CP4 - Failed Ishihara and lantern test but able to pass coloured wire test CP5 - Failed coloured wire test. He had not done the wire test at the time but everything went forward. Oct - went to Rosyth for his PRNC and passed, he already had a joining date of Jan 2015 so getting ready for that. Week later he got a phone call from Careers Office - can he join following Sunday! Agghh, not really, at work and no kit bought / prepared - Careers Office then asked if he could join two weeks later - that is, this Sunday coming. Yes - so off he goes, hands his notice in and starts getting ready for joining. Yesterday late afternoon, gets a phone call from Careers Office, can you come in for the colour blindness wire test? Now his mom is panicking - bit late, what if he fails etc. etc. Bloody Navy, couldn't organise a p"£$ up in a brewery etc. etc. (Can tell she was married to the mob for 12 years!) Anyway, he went in today and passed so still going in this weekend. The interesting part is that the wire test is a match of a number (30?) or so wires of differing colours. The Careers Adviser came in to check he had done it right and had to go out and get another person to make sure because he couldn't actually hand on heart tell himself - said CA is a Colour Sgt RM I'm of an opinion that the tardiness in the wire test being done is a result of whatever agency is running the medicals - when he went for his medical the doctor had not read his notes and therefore not prepared for half the stuff that was declared on the medical form my lad had to fill. The doctor asked questions that my lad had to phone and ask me the answers to (lads are like that), those questions were answered in the notes the doctor opened afterwards. Anyway - rattling on now so I'm off.
