State Supplementary Payment Program

State Supplementary Payment Program

In 1974, the U.S. Congress established the Supplemental Security Income (SSI) program to provide basic supports for individuals who have attained age 65, or are blind or disabled.  Some states supplement the federal SSI payment with state-only dollars.  In Washington State, the state-funded supplement to the SSI is the State Supplementary Payment (SSP).

Clients must be eligible for SSI cash benefits or Social Security Title II benefits as a disabled adult child and would be eligible for SSI if it were not for the receipt of these benefits. 

Currently SSP is closed to new enrollees with the exception of SSP Pre-Vocational Legacy (PVL).

To be eligible for SSP PVL, a person must:

  • Be a client of DDA;
  • Have exited a DDA Prevocational employment service after September 1, 2015;
  • Not be currently be enrolled in a DDA Prevocational Program;
  • Not be currently enrolled in a DDA Residential Habilitation Service such as Companion Home, Alternative Living, Supported Living, State-Operated Living Alternative (SOLA), Group Home, Foster Home, or Staff Residential;
  • Be Eligible for or receive supplemental security income (SSI) cash assistance in the month in which the DDA/SSP Pre-Vocational Legacy is issued; or receives Social Security Title II benefits as a disabled adult child and would be eligible for SSI if they did not receive these benefits.
