That's right, the OSCE certainly isn't a true representation of a persons competence. I've always struggled with OSCE's even at uni, i just can't act natural in that kind of environment- but i am a excellent nurse (if i say so myself), as i'm sure you all are too. What gripes me if that in this OSCE people are failing for medial reasons, I think unless we are unsafe in our practice- administering wrong medication, breaking antt, documenting something incorrectly then certainly fail us.. but otherwise, throw us a bone and understand we're in an extremely stressful situation.
As far as i know a trust hires you either privately or through an agency and they provide the training however you're locked into a 2 or 3 year contract. Again, i am so pro training days, information meetings etc etc but if it is going to be made available for one then it must be available for all. standard.
