Judith Pratt holds an MFA from American University, an MA in Modern and Contemporary Art History from Christie's Education, New York, and a BA in Fine Arts from The Catholic University of America. Research for her master's thesis is supported by the Stettheimer holdings at Columbia University's Rare Book and Manuscript Library, Yale University's Bienecke Rare Book and Manuscript Library, and MoMA's Research Facility. Concurrently, she served as a curatorial assistant in the Contemporary Drawings and Prints Department at The Morgan Library and Museum, New York.

Pratt was awarded a 2022/23 Fellowship from the Virginia Museum of Fine Arts, selected as a Trawick Prize finalist in 2022, and further designated a Sondheim semifinalist in 2020. In 2021/2022, her work was featured in the Taubman Museum of Art's Triennial Exhibition in Roanoke, VA curated by Nandini Makrandi. In 2021, Pratt's outdoor sculpture was selected by curator Sarah Tanguy and installed at Oxon Hill Manor, a historic site adjacent to D.C.'s National Harbor complex. The installation was made possible by the Arts and Cultural Heritage Division of the Maryland National Park and Planning Commission. Pratt's work was further featured in solo exhibitions at Hillyer Art Space in Washington, D.C. as well as Second Street Gallery in Charlottesville, VA. In 2019, Pratt's work was also selected for Arlington Art Center's Regional Biennial curated by Blair Murphy. During the same period, her work was included in numerous group shows including Hillyer Art Space's Micro-Monuments II: Underground curated by Artemis Herber and juried by Laura Roulet. Her work also was featured in Uprooted, a juried exhibition by Adriel Luis, curator at the Smithsonian's Asian Pacific Center.

The Jewish Museum in New York included Pratt's thesis on American Modernist artist Florine Stettheimer as a scholarly source for its Stettheimer retrospective in 2017. The thesis titled OrphÈe des Quat'z' Arts: A Personal Passage into American Modernism supports Stettheimer's performance and sculptural work as pivotal in the rise of performance art during the Postmodern era.

She was also selected to join a group of international artists in the inaugural Art Lab Residency Program sponsored by the University of Virginia's Mountain Lake Biological Station, with emphasis on combining the visual arts and science in a mutually experimental inquiry. Her artwork has been featured in four editions of the literary journal Raritan: A Quarterly Review, published by Rutgers University.
