English learners (ELs) are one of the fastest-growing student groups in the U.S. K-12 system, making up about one in 10 students enrolled in public schools nationwide. Despite research showing that EL students need more resources and supports to be successful in school, funding at the federal, state, and local levels to provide those additional resources is largely inadequate and not well targeted to students' needs. This brief addresses the following questions: (1) Why is funding for EL students important? (2) What characteristics in the EL population are important to consider in funding systems? and (3) How are programs and services for EL students currently funded?
