Final answer:
The No Child Left Behind (NCLB) Act of 2002 ended the policy promoting bilingual education since the 1960s but was later replaced by the Every Student Succeeds Act (ESSA) in 2015, reflecting changes in educational policy towards non-English speakers in the United States.
Step-by-step explanation:
The law that ended the policy promoting bilingual education since the late 1960s was the No Child Left Behind (NCLB) Act enacted in 2002. This policy shifted the focus towards English-language learning and accountability for schools, but over time, its requirements became unworkable and it was criticized for underfunding and inadequate provision of bilingual education.
The law was due for revision in 2007; however, it was not until the Every Student Succeeds Act (ESSA) in 2015 that NCLB was replaced. ESSA provided more flexibility to states, potentially affecting bilingual education by not mandating strict federal approaches. Despite ongoing controversy and debate about bilingual education in the United States, policy changes have been influenced by varying views on assimilation and the educational needs of non-English-speaking students.
