my enhanced CRB is messed up too... I've been told by the job centre to never apply for any jobs working with children or vulnerable adults as chances are I'd never get them due to my CRB

. Not sure if unis do them though, maybe for certain degrees, not sure.
However, the times I have applied for such jobs they have given me a chance to explain the things away. Esspecially with sections, I only have two on there, but with one of them it clames that I assulated a police officer (I didnt

) but most employers have called me to get more information and given me a chance to essentially explain that I;m not dangerous nor really a criminal.
I have one thing (which would rather not go into publicly) on my CRB that does cause me trouble with employment and stuff, but that's not mental health or section related. theres also 'rehabilitation period’ thing, I can't rememberthe specifics, but if you google "rehabilitation offenders act 1974" you should be able to find out about it, basically its a time period after which crimes are classed as "spent"
CRB stuff factored into my deciding to leave uni... I wanteed to be a surgeon, but with my bakground it was unrealistic
