This bill, known as the "All Students Count Act of 2026," amends the Elementary and Secondary Education Act of 1965 (ESEA) to enhance the reporting of student performance data. It addresses the need for more granular data on annual state report cards, particularly for Asian American and Native Hawaiian and Pacific Islander students. The legislation recognizes the significant diversity within these populations, which are often inaccurately treated as homogeneous groups in educational data. To rectify this, the bill mandates that states disaggregate data for numerous specific ethnic subgroups under both the Asian American and Native Hawaiian and Pacific Islander categories. For instance, it lists subgroups like Chinese Filipino Vietnamese Hmong for Asian Americans, and Native Hawaiian Samoan Chamorro for Pacific Islanders, aligning with decennial census classifications. This detailed reporting aims to identify and address unique educational disparities, ensuring that support can be more effectively tailored to the distinct needs of these diverse student communities. The amendments are set to become effective 18 months after the bill's enactment.
