The SSI program went into effect in January 1974. If you were eligible for assistance under one of the prior Federal/State matching grant programs for the aged, blind, or disabled in December 1973, you were “converted” to SSI. Congress wanted to be sure that you were not disadvantaged by your conversion to SSI. Therefore, it enacted certain special provisions applicable only to you as a converted recipient. These special provisions are called “grandfather” provisions and are discussed in §2172.
