Welcoming, Registering, and Supporting Newcomer Students: A Toolkit for Educators of Immigrant and Refugee Students in Secondary Schools, from The Institute of Education Sciences (IES), is intended to help educators and other stakeholders identify and use research-based practices, policies, and procedures for welcoming, registering, and supporting newcomer immigrant and refugee students who are attending secondary schools (grades 6-12) in the United States. The research and resources in the toolkit are divided into four areas: welcoming and engaging newcomer immigrant and refugee students, registering newcomer immigrant and refugee students, building educators’ capacity to support newcomer immigrant and refugee students, and supporting newcomer immigrant and refugee students. Resources include professional development curricula, policy and implementation guides, evaluation reports, and sample surveys and assessments.
