A provision across numerous federal grant programs, such as Title I that allocates district funds based on the number of low-income students they serve, that requires federal funds to add to (or supplement) and not replace (or supplant) other funds (state/local) in providing general educational services. This provision has been part of the  Elementary and Secondary Education Act (ESEA) and other federal grant programs since 1970 and is maintained in the Every Student Succeeds Act (ESSA). The purpose of the provision is to ensure that federal funds are utilized to benefit the intended population in the authorizing statute and not being used to fund the basic education that the LEA would have provided in the absence of federal funds.8
