What job might my son get in the US Air Force?

[Oreo]

My son is exploring the idea of joining the US Air Force. He just took the ASVAB and will get the results at the end of this month. He has not met with a recruiter at this point, yet.

I understand that jobs he will be offered are based on ASVAB scores. My son is not a scholar. He’s a below average student but really wants to be an aircraft mechanic or another kind of job where he can use his hands (do repairs, diagnose, etc).

Is there a possibility he could be assigned to his dream job? Is it more about current needs of the USAF regardless of education (ASVAB score)? What might he expect?

Thanks for any and all help.
