Teachers working with English Learners (ELs) will find this tool kit produced by the US Department of Education's Office of English Language Acquisition (OELA) extremely valuable! You can download more FREE resources here... https://www2.ed.gov/about/offices/list/oela/resources.html.
OELA’s EL Tool Kit was published in 2015 as a companion to support the 2015 Dear Colleague Letter (DCL) produced by the Department of Education, Office for Civil Rights, and the Department of Justice, outlining legal obligations for ELs. Some chapters of the tool kit have been updated related to the Every Student Succeeds Act of 2015 (ESSA).
The English Learner Tool Kit helps state and local education agencies meet the needs of ELs by providing helpful research, sample tools and resources.
