This archive contains approximately 4,500 documents, primarily consisting of program evaluations from 2000 to 2023.

Originally compiled in 2023 by Ketevan Gallagher as part of a student research project, the archive focuses on English-language program evaluations from 2000–2023, including impact evaluations. 

In 2025, following the sudden shutdown of USAID’s official DEC website, access to many publicly funded evaluation records was disrupted. These materials—produced at significant cost and intended to support transparency and accountability—were at risk of being lost. 

In response, researchers and institutions mobilized to preserve what they could. At the request of academic partners, AidData at William & Mary began hosting and expanding this archive to ensure continued public access.

Documents were identified based on how they were labeled and categorized within the DEC at the time of collection. As a result, the corpus may not include every evaluation from this period, and it may include a small number of documents that are not evaluations due to inconsistencies in original metadata and classification.
