Grants are a form of financial aid, based on need, which you do not have to repay.
Federal Grants
Federal grants are based on financial need as determined by completion of the FAFSA or Renewal FAFSA application. To apply for all federal grants, you need to complete the FAFSA as close to January 1 as possible. Funding for FAFSAs received after March 1 is not guaranteed.
Students from states other than Oregon should check with their home state higher education office to see if there is funding available to them while attending a school outside their home state.
