Writing Across the Curriculum (WAC) began in the 1970s as an educational reform movement committed to innovations in curriculum development and movements between disciplinary boundaries. Its organizers recognized that thinking and learning are life-long projects that often move between academic majors and disciplines. WAC hopes to foster creative collaboration between the curricula through writing.

Drawing on writing and teaching initiatives begun by Rosemary Palms and Richard Perry in the early 1980s, Writing Across the Curriculum at Pratt Institute formally began in 1993, under the guidance of Amy Brook Snider. The goal of the faculty project was to reflect on the ways that writing can complement the teaching and learning process. The program today, under the direction of Kathryn Cullen-DuPont, builds its varied services on the notion that good writing and thinking are inseparable.

As a creative form of expression and a forum for exchanging ideas, writing can foster complex thinking among students, allowing them to act in the larger world. Writing can challenge what educational theorist Paolo Freire has called the "banking concept of education," in which students function solely as empty vaults that must be filled with the coins of knowledge. WAC encourages, therefore, writing and critical thinking as tools that help students participate actively in their studies.
