The act and NCLB say that the accommodations that it provides should be interpreted in concordance with federal civil rights laws. "As interpreted by the U.S. Supreme Court, Congress, and federal civil rights officials, these provisions rely on terms like “affirmative steps” and “appropriate action” that give school districts the discretion to use a range of instructional approaches. As a result, under both Title VI and the EEOA, courts and federal enforcement agencies must decide on a case-by-case basis whether programs are in fact overcoming linguistic barriers to full participation." The policy still remains highly-debated at both the state and federal level.
