The School Improvement Grants (SIG) program is authorized by section 1003(g) of the Elementary and Secondary Education Act of 1965 (ESEA). Under section 1003(g)(1) of the ESEA, the Secretary must "award grants to States to enable the States to provide subgrants to local educational agencies for the purpose of providing assistance for school improvement consistent with section 1116." From a grant received pursuant to that provision, a State educational agency (SEA) must subgrant at least 95 percent of the funds it receives to its local educational agencies (LEAs) for school improvement activities. In awarding such subgrants, an SEA must "give priority to the local educational agencies with the lowest-achieving schools that demonstrate: (1) the greatest need for such funds; and (2) the strongest commitment to ensuring that such funds are used to provide adequate resources to enable the lowest-achieving schools to meet the goals under school and local educational improvement, corrective action, and restructuring plans under section 1116." The regulatory requirements expand upon these provisions, further defining LEAs with the "greatest need" for SIG funds and the "strongest commitment" to ensuring that such funds are used to raise substantially student achievement in the persistently lowest-achieving schools in the State. This guidance includes revisions and additional questions to previously published guidance reports.
