Is it possible yes...is it likely NO! My husband was a Senior Chief when he retired and he had many of a young men go to Captains Mass (himself included when he was much longer). It is not a good thing but it is not the end of the world. He may get some of his rank taken away a reduction in pay and restricted to base.
It will be okay. Don't stress.
It is possible he will be kicked out for what you said he did, but not likely as Carrie said. I am a retired Chief and my last command was the "A" Schools
What can happen if found guilty of cheating, is he will loose his "A" School, get 45 days restriction, 45 days extra duty, loose 1/2 months pay for two months, and be busted down a pay grade. After the time is served he will be sent out to the fleet as undesignated. They take cheating very seriously.
Not sure about the being in the car issue...sounds like there is more to it.
My son just received 45 days restriction and loss of pay for 2 month. Not sure if his A school was taken. Haven't heard from him. The strange thing about this situation is they allowed him to continue on to C school (dental assistant) after he was removed from A school (corpsman) 3 weeks prior to graduation. The information I received from his friend was he left base while he was on duty. He is an adult so he is responsible for his own actions. My concern is will he be able to continue with A school?
I see you've started quite a few threads on this topic, but I'll choose this one to answer.
While my son was in A school (or maybe ATT I can't recall), the sailor next to him was struggling and my son whispered "you're overthinking it". Well the proctor heard and accused both of cheating.
It ended up being a long drawn out affair as my son's case was pushed up the chain of command. They arranged for my son to have legal counsel there who advised him to stick to his guns no matter what. The Navy played games with both sailors playing good cop, bad cop and telling each separately that the other had admitted to cheating. My son stuck with the truth, even though the other sailor in a panic said they were cheating.
The end result was, my son's scores were high enough that he was allowed to stay. The other sailor was booted out the following week.
FWIW, his case went up the chain of command just short of Captain's Mast, where he was told if it got that far, they would both be kicked out.
I'm not trying to scare you, just giving you the facts of his case. If you do get to talk to him, warn him that the Navy is not beyond misleading you to have a reason to remove you.
