ACF issues this Information Memorandum (IM) to set forth its interpretation of the phrase “public assistance” in Sec. 645 of the Head Start Act to include the Supplemental Nutrition Assistance Program (SNAP). Adopting this interpretation will make it easier for eligible families to enroll children in Head Start services by allowing families to demonstrate proof of SNAP receipt or eligibility to enroll in Head Start and will simplify the process of determining program eligibility for grantees.
