Today’s classroom has many English Language Learners (ELL), once referred to as English as a Second Language (ESL) or Limited English Proficiency (LEP). There are over 4 million students in public education classified as ELL—and these numbers continue to rise. In the 1990s, there were 14 million immigrants who moved to the US, and there were 14 million more between 2000 and 2010. In fact, ELL students are the fastest-growing student population according to the National Council For Teacher Education (NCTE).
