My colleague Mary Ann Zehr recently wrote in her Learning the Language blog about a Government Accountability Office report on teacher preparation programs. The report notes that the programs generally require a class in teaching students with disabilities, but very few have that same requirement for teaching students who are English-language learners.
The broader conclusion of the GAO report is that several federal programs support training teachers in special education and instruction of ELLs, but that better coordination in the Education Department would help coleges and universities more.
