For Social Security purposes, a person with 40 quarters of coverage is considered.

A person is considered partially insured if they have earned at least six quarters of coverage but do not meet the full requirement of 40 quarters. This status grants limited access to benefits, such as the ability to receive disability benefits only under certain conditions, but does not provide the full range of benefits available to fully insured individuals.

The currently insured status requires an individual to have at least six quarters of coverage in the last 13 quarters. This classification is temporary and does not equate to the comprehensive benefits associated with being fully insured, which necessitates the full 40 quarters of coverage.

There is no classification of "conditionally insured" within the Social Security framework. This option may imply a temporary or contingent status, but it does not exist and is not relevant to the criteria set forth by the Social Security Administration.
