Fully Insured Status
Definition
Earned by accruing 40 quarters of coverage (~10 years of work). Unlocks the full menu: retirement, disability, premium-free Medicare Part A, and survivor benefits.
In plain English
The master key — ten years of work opens every Social Security door.
Exam tip
Most Social Security benefits are ONLY paid to fully insured workers. 40 quarters = 10 years — memorize. (Technically the floor scales with age — 1 credit per year after 21, min 6; 40 makes it PERMANENT.)
Easy to confuse with
These are what this term gets tested against — if you can't tell them apart cold, drill the contrast.
