OPR

OPR is an acronym that can refer to several different concepts, organizations, or metrics, depending on the context. There is no single universally accepted meaning, so the intended sense is usually clear from the field or institution involved.

Common meanings include:

- Office of Professional Responsibility: A designation used in the United States Department of Justice and various law-enforcement or legal institutions for a unit that investigates professional misconduct or ethics concerns involving attorneys and other personnel.

- Operational Readiness Review: A formal process to verify that a system, program, or operation is prepared for deployment and sustained operation, covering procedures, staffing, safety, and contingencies.

- Operating Profit Ratio: In finance, a ratio that expresses operating income as a percentage of revenue, used to gauge the efficiency of core business activities. The term is less common than operating margin, but some sources use OPR.

- Office of Policy and Research: A generic label for government or organizational units that combine policy development with research activities, found in various agencies and institutions.

- Office of Population Research: A name used by some universities for research centers focusing on demography and population studies, occasionally abbreviated as OPR.

Because meanings vary widely across sectors, the precise definition of OPR should be determined from the surrounding context, such as the organization, field, or document in which the acronym appears. When ambiguity remains, consulting a glossary or the issuing entity can clarify which OPR is intended.
