Judith Pratt holds an MFA from American University, and an MA in Modern and Contemporary Art History from Christie's, New York. She also served as a curatorial assistant in the Modern and Contemporary Drawings and Prints Department at New York's Morgan Library and Museum.

In 2022 Pratt became the recipient of the 22/23 Virginia Museum of Fine Arts Fellowship Award, Richmond, VA. She also was selected as a Trawick Prize Finalist in 2022. In 2021-2022, her work was featured in the Taubman Museum of Art's Triennial Exhibition in Roanoke, VA curated by Nandini Makrandi. Her outdoor sculpture is currently installed at Oxon Hill Manor adjacent to D.C.'s National Harbor complex through 2023. The outdoor installation is made possible by the Arts and Cultural Heritage Division of the Maryland Park and Planning Commission in conjunction with State Department's Art in Embassy's Program curator Sarah Tanguy. In 2017 and 2018, Pratt's work was featured in solo exhibitions at Hillyer Art Space in Washington, D.C. and at Second Street Gallery in Charlottesville, Va. In 2019, Pratt's work was also selected for Arlington Art Center's Regional Biennial. Her work was included in simultaneous group shows at Hillyer Art Space's Micro-Monuments II: Underground curated by Artemis Herber and juried by Laura Roulet as well as Uprooted, a juried exhibition by Adriel Luis, curator at the Smithsonian's Asian Pacific Center.

Pratt was awarded a VCCA Residency in 2014 to Auvillar, France. 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.

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 Orphée 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.  

Pratt's work has been reviewed in Artnews, The Washington Post, and East City Art. She has lectured at Christie's Education, New York, taught at Trinity College and American University in Washington, D.C., and lectured at Maryland Institute College of Art in Baltimore. She is currently on the Advisory Board of the Washington Sculptors Group, a 400-member organization that provides opportunities for artists in the Mid-Atlantic region.
