The population of English learners (ELs) in K-12 schools continues to grow. Between the 2009-10 and 2014-15 school years, the percentage of English learners increased in over half of the states, and in 2017, English learners made up 10.1% of the total student population. Research suggests that in their transition to English, non-native speakers fall behind academically, which can intensify the longer a student remains in an English learner program. State education leaders are mindful of this and have implemented policies to identify, serve and reclassify English learners as they become proficient. The percentage and number of English learners per state provided herein is from the National Center for Education Statistics.
