Many requests for project changes during the award life cycle are routed through Harvard's Grants Management Application Suite (GMAS). Some may require advance sponsor approval. Approval requirements for most federal agencies can be found in the FDP Prior Approval and Other Requirements Matrix posted by the National Science Foundation. Note that rules for project changes vary between federal agencies and non-federal sponsors. When making changes to a foundation grant or a grant from a federal agency that is not listed in the FDP Matrix, be sure to refer to sponsor policy and the award terms and conditions.
