This issue of NASET’s Inclusion Series is taken from the U.S. Department of Education. On January 16, 2025, the U.S. Department of Education released the guidance document, Building and Sustaining Inclusive Educational Practices Aligned with the Elementary and Secondary Education Act of 1965 (ESEA) and Part B of the Individuals with Disabilities Education Act (IDEA), to help state educational agencies, local educational agencies, and school staff to foster inclusive and effective learning environments. This issue of the Inclusion Series will present the letter from the U.S. Department of Education explaining the rationale for the document and then provide the link needed to access the guidance document, Building and Sustaining Inclusive Educational Practices.
