This "Biennial Report to Congress on the Implementation of the 'Title III' State Formula Grant Program, School Years 2012-14" is the sixth report of states' self-reported data about English learners (ELs) receiving services in "Title III"-supported language instruction educational programs (LIEPs). The biennial report to Congress on the implementation of the "Title III" state formula grant program provides a snapshot of the status of the U.S. Department of Education's (the Department's) efforts to hold states accountable for ensuring that all ELs attain English language proficiency (ELP) and are achieving in the content areas of mathematics and reading/language arts at the same high level set by the states for all students. "Title III" of the "Elementary and Secondary Education Act" ("ESEA"), which focuses on the specific goals of serving ELs with effective LIEPs, was first implemented upon the reauthorization of the "ESEA" by the "No Child Left Behind Act of 2001." This report contains data reported by state educational agencies (SEAs) representing the 50 states, the District of Columbia, and the Commonwealth of Puerto Rico related to the education of ELs for school years (SYs) 2012-13 and 2013-14.
