[Excerpt] The primary source of federal aid to K-12 education is the Elementary and Secondary Education Act (ESEA), particularly its Title I, Part A program of Education for the Disadvantaged. The ESEA was initially enacted in 1965 (P.L. 89- 10), and was most recently amended and reauthorized by the No Child Left Behind Act of 2001 (NCLBA, P.L. 107-110). Virtually all ESEA programs are authorized through FY2008. During the current 110th Congress, congressional hearings are being conducted in anticipation of subsequent consideration of legislation to amend and extend the ESEA.
