What is an "original classification authority" (OCA)?

An "original classification authority" (OCA) refers specifically to a designated official with the legal authority to determine that information requires protection against unauthorized disclosure for reasons of national security. This classification can only occur in the first instance; the OCA is responsible for assigning a classification level (such as confidential, secret, or top secret) based on established criteria.

This role is crucial in ensuring that sensitive information is correctly identified and protected from disclosure, which ultimately supports national security interests. The other options do not accurately capture the unique role of an OCA; for instance, simply reviewing classified materials or having general access does not confer the authority to classify information originally. Likewise, the authority to only declassify is not included within the OCA's primary responsibilities, which specifically focus on the initial classification of information.
