Arts integration differs from traditional education by its inclusion of both the arts discipline and a traditional subject as part of learning (e.g. using improvisational drama skills to learn about conflict in writing.) The goal of arts integration is to increase knowledge of a general subject area while concurrently fostering a greater understanding and appreciation of the fine and performing arts. The John F. Kennedy Center for the Performing Arts defines arts integration as "an approach to teaching in which students construct and demonstrate understanding through an art form. Students engage in a creative process which connects an art form and another subject and meets evolving objectives in both."

Arts integration is related to arts education in schools. Arts education, while existing in different forms during the 19th century, gained popularity as part of John Dewey's Progressive Education Theory. The first publication that describes a seamless interplay between the arts and other subjects (arts integration) taught in American schools was Leon Winslow's The Integrated School Art Program (1939). For the remainder of the 20th century, arts education's role in public schools ebbed and flowed with the country's political leanings and financial well-being.

According to Liora Bresler, during the 1970s and 1980s, two advocates for arts integration emerged: Harry Broudy and Elliot Eisner. Broudy advocated for the arts on the basis of strengthening the imagination. Broudy viewed imagination as an essential component of learning that should be cultivated in schools, and he advocated for the integration of aesthetic education into all subject matters in his work, Enlightened Cherishing. Eisner followed Broudy, citing that the arts were important to varying types of cognition. He believed that arts brought about a deeper understanding of the world due to their interactivity—the arts move learning beyond what is written or read.

Cassandra B. Whyte emphasized the importance of artistic experiences for students to encourage creative and independent thought processes that would be important throughout an individual's lifetime. The arts helped students with problem solving and decision making and those processing experiences could be adapted in general life situations. Whyte advocated including aspects of art education with locus of control identification counseling experiences to help higher education students develop confidence in their unique problem solving abilities in the classroom and in life.

Formerly, No Child Left Behind legislation describes arts education as "essential to every child's education," and include it as one of the Core Subjects. No Child Left Behind legislation also emphasizes accountability through assessment (often taking the form of the standardized test.) While no standardized assessment has been mandated in any of the arts, the need for academic accountability in the arts, as well as in other academic subject areas, has led to increased research on and advocacy of arts integration and its impact on student learning.

Currently, Common Core and close adaptions of it are changing the way schools approach learning. Common Core's approach to art integration is that it enhances education by making learning interesting and fun. With Common Core becoming the norm for many school districts through the United States, teachers are integrating art into the classroom now more than ever. The rise of popularity in art integration has increased the amount of resources available to include the classroom, making it easier than ever to use art integration in the classroom.

Arts advocacy discourse currently presents two main opposing views in support of arts in education. The first points to economic grounds that art teaches "21st-century skills" like collaboration and innovation, which are necessary only as a means to breed productivity for the growth of the market. The second, alternative approach focuses instead on the philosophical value of creative inquiry that art instills in students, arguing lifelong development with no end in mind as a necessary habit borne out of an arts education. Tension between the utilitarian, workplace-focused view and the educational, growth-centered framework on advocacy continues to shape and reshape the arts education universe as revisions to the National Core Arts Standards reflect fluctuations in advocacy rhetoric. 

The impetus for the arts integration is a growing body of research that demonstrates how learners experience success when taught why and how to use music, visual art, drama/dance, theatre and the literary arts to both express and understand ideas, thoughts and feelings. Critical Links, a compendium published by the Arts Education Partnership (AEP^{[permanent dead link]}), includes 62 studies which examine the relationship between arts learning, academic achievement, and social development of students. Highlights include studies which explore the use of drama to increase students' reading comprehension and studies which examine the relationship between music and math concepts. The Arts Education Partnership has also published The Third Space, which profiles ten arts-integrated schools across the United States.
