The Arts Education for All Act expands arts education across multiple federal education programs and juvenile justice initiatives. The bill requires states and local school districts to incorporate arts education into their improvement plans, including increasing the number of arts teachers and integrating arts instruction into other subjects like math and reading. It also mandates that schools report data on arts course offerings, student enrollment in arts classes, and teacher qualifications in their school report cards, with particular attention to equity gaps between high-poverty and low-poverty schools. Additionally, the bill incorporates arts education into early childhood programs, afterschool and summer learning centers, programs for incarcerated youth, and adult reentry initiatives, while requiring the federal government to conduct research on effective arts education practices and reinstate national assessments in the arts. The legislation does not specify new funding amounts or implementation timelines, instead amending existing education law to prioritize arts education across these programs.
