This report describes Supplemental Education Services (SES) within Wake County Public School System (WCPSS) in terms of the schools, providers, and student participants in 2008-09 and 2009-10. It is the first in a series of three reports related to SES. NCLB requires schools receiving Title I funding in their second year of school improvement to offer eligible students SES in addition to existing Title I services. The SES programs for WCPSS in 2008-09 and 2009-10 were in compliance with federal guidelines to make available an SES program, enroll only FRL students, and to use state-approved vendors to deliver the program. SES is designed to improve the achievement of FRL students who score below, at, or above grade level. Therefore, service to some students may help schools reach AYP standards while service to others may help individual students and schools reach ABCs and other standards of academic success. An appendix explains the steps in SES analysis.
