Federal Contracting Acronym
PWS
Performance Work Statement
Plain-English definition
A Performance Work Statement defines results the contractor must achieve rather than prescribing how to perform work. Agencies prefer PWS language for service contracts where innovation and efficiency are encouraged. Evaluators score proposals on how well offerors meet performance standards and quality measures.
Why it matters
PWS-based procurements reward outcome-focused proposals; copying SOW-style boilerplate can score poorly.
Where you will see it
Federal notices on SAM.gov, contract attachments, registration systems, audit requests, and internal capture/proposal documentation.
Example in context
When reviewing a solicitation, a contractor confirms how PWS is used in the notice, whether related clauses apply, and which internal subject-matter experts should validate the response.
