For most schools, yes. Even if one school doesn't require it on FAFSA, another school will, so you might as well do it and get it over with. The ones that don't will require it on their own forms. Get used to providing it over and over again. The parental info will only be used for a shool's own loans/grants/scholarships, so it can't hurt you to provide it. The feds will ignore it in calculating your EFC.
