My son is 17 and wants to join the Navy as a Seabee. He is concerned that his ASVAB score will not be high enough to get in. Does anyone know how much weight this score has for this division? Also, if he joins with another job can he change jobs once in to get into the Seabee's. We are really confused and from what the recruiter has told us, and I don't know if I believe everything, that after 18 months he can retake the ASVAB and get into the Seabee's then. Please if anyone has any advice for my son can you help us out.
