Abt Associates (Abt) mailed letters to approximately 15,000 beneficiaries over this 3-month period to solicit volunteers for stage 2 of the Benefit Offset National Demonstration (BOND) project. If a beneficiary volunteered and was randomly assigned to a $1 for $2 treatment group, the BOND work continuing disability review (CDR) unit coded the disability control file (DCF), indicating that the beneficiary is a BOND participant. For a definition of a BOND participant, see DI 60099.015A.

Abt notified 80,000 beneficiaries of their automatic eligibility in the BOND project by sending a “good news” letter to each BOND participant in stage 1. The BOND work CDR unit coded the DCF, indicating that the beneficiary is a BOND participant. For a definition of a BOND participant, see DI 60099.015A.

Abt actively recruited and enrolled volunteers for stage 2 by sending 20,000 letters each month until we reached 12,600 volunteers. The BOND work CDR unit codes the DCF indicating that the beneficiary is a BOND participant when a beneficiary volunteers to participate in the demonstration project and is assigned randomly to a $1 for $2 treatment group. We do not code the DCF for those randomly selected to the control group. For a definition of a BOND participant, see DI 60099.015A.
