Mike,
Does your son know the coursework required for engineering? Have you, or has he taken an honest assessment about strengths/weaknesses in relation to said coursework?
Does your son know what a typical day as an engineer would entail? And if so, is he still interested?
Has your son ever worked before? Either for himself or 'the man'?
Is your son unusually candid or skilled in math and spatial reasoning?
Have him go on a job shadow/mentoring experience with actual engineers that aren't friends/family so that he can get an honest look for himself.
