The No Child Left Behind Act of 2001 (NCLBA) requires districts with schools that have not met state performance goals for 3 consecutive years to offer their low-income students supplemental educational services (SES), such as tutoring, if these schools receive Title I funds.

SES are provided outside of the regular school day by a state-approved provider, with responsibility for implementation shared by states and districts. GAO examined (1) how SES participation changed between school years 2003-2004 and 2004-2005; (2) how SES providers are working with districts to deliver SES; (3) how states are monitoring and evaluating SES; and (4) how the Department of Education (Education) monitors and supports state implementation of SES.
