Can I win my appeal with the NJ Civil Service Commission and NJDOC?

Through a security background check, the NJDOC found my criminal record unsatisfactory. The letter states I was craged with 2c:33-2 Disturbing the peace and a 4th degree 2c:29-2a resisting arrest. The letter s states that these charges were conditionally disposed on 12/7/05 through a successful diversion program to include an intake service conference. The resisting arrest charge was diverted and the disturbing the peace charge was dismissed on 1/5/06 after the conditions were met. This incident happened 9 years ago when I was 12. They guy I spoke to at the court never said I had to take part any programs or anything of that nature. My mother never even signed a paper. The guy also said that no charges were going to be filed and now 9 years later through a background check for a law enforcement position, I am a criminal. I have never been in trouble with the law after that. Do I have a case? I am studying criminal justice, can I have a career in law enforcement with this out there?
