Title 50 › CHAPTER 38 — CENTRAL INTELLIGENCE AGENCY RETIREMENT AND DISABILITY › SUBCHAPTER III — PARTICIPATION IN FEDERAL EMPLOYEES’ RETIREMENT SYSTEM › § 2151
Most Agency employees whose work after December 31, 1983 counts for Social Security must be covered by the Federal Employees’ Retirement System (chapter 84 of title 5). People who were in the Agency Retirement and Disability System on or before December 31, 1983 and who have not had a break in service longer than one year since then stay in that older system instead of moving into FERS. FERS also does not apply to anyone who later left federal service after being under the older Agency rules, or to Agency employees with at least five years of civilian service before January 1, 1987 that counts under those older rules. Those people can choose to join FERS under the rules. Employees made participants after December 31, 1987 must elect within six months, the choice starts the next pay period, and it cannot be changed. Special rules in this subchapter control if they conflict with chapter 84.
