If he has a W-2 with boxes 3-6 blank, you don't need the SE version (unless he has cash side income to report such as from weddings and funerals -- in that case he is acting as an independent contractor for those wages.)
If he has a 1099-MISC or only receives a housing allowance with no income taxable wages or W-2, then you need to use the self-employed version to get the SE taxes on the housing allowance calculated correctly.
