First, the Rand Corporation, the well-respected and independent think tank which has a national presence and broad influence on federal policies, has investigated dual language instruction in the United States. Their review and analysis of immersion programs found that such instruction raises student achievement in English. Students enrolled in immersion programs out-paced and out-performed their peers on measures of academic achievement, all of which aligns with other research on the TWI and related instruction.

Second, the Houston Education Research Consortium (HERC) and the Kinder Institute for Urban Research, both of which are housed at Rice University, released a report on English Language Learners utilization of school choice programs in Houston ISD. Despite such programs being at the core of education efforts and the growing number of ELLs in the district, the authors found that ELLs were not enrolling in such programs or magnet schools. The authors "found significant differences in the likelihood that EL students engage in school choice, raising important questions about whether schools of choice are accessible to current ELs."
