Also known as

(Period of Performance) is a metric concept federal contractors and grant writers run into across solicitations, regulations, and award filings
POP is a measurement used in federal contract evaluation, source selection, oversight, or performance management. For example: Example: The Simplified Acquisition Threshold or a fiscal-year budget measure. Understanding POP matters because evaluators use metrics like it to compare proposals quantitatively, score past performance, set award-fee outcomes, and decide who gets the next option year. Contractors who track how POP is calculated — and what target values look like in their NAICS or service area — write proposals that are concrete and defensible instead of generic and easily dismissed. POP also has implications for contract administration: getting the calculation methodology wrong post-award is a common source of disputes and contracting-officer modifications. Pair POP with the related metrics above to see how the federal government composes evaluation criteria into source-selection narratives.
