SL 30001.310 Section 218 Coverage Groups
When a State enters into a Section 218 Agreement, employees are brought under the agreement in groups known as “coverage groups.” There are two types of employee groupings for coverage purposes:
absolute coverage groups (Section 218(b)(5)), composed of positions not under a retirement system; and
retirement system coverage groups (Section 218(d)), composed of positions under a retirement system.
The State decides which groups to cover and the effective date of coverage, subject to Federal and State laws.
