If the child is away at school, obtain an SSA-788 from an authorizing school official,
                  in addition to an SSA-781 from the claimant. If the child is attending college (while
                  under age 16), in lieu of the SSA-788, obtain a statement from the child showing contributions
                  by the claimant, whether the child spends vacations with the claimant, and whether
                  the claimant writes or gives instructions in any way.
