 In 2002, for example, the implementation of the English Language Acquisition, Language Enhancement, and Academic Achievement Act of the No Child Left Behind Act made it requisite that schools with large numbers of language-minority students provide instruction that facilitates their acquisition of English to perform well on standardized tests consequently .There are now 398 two-way immersion programs in 30 states and the District of Columbia.The number of programs has increased significantly in the last decade, despite efforts made in states such as Arizona and California to eradicate bilingual education programs in favor of English-immersion, with the passing of Proposition 203 and Proposition 227, respectively.
