The Discovery Fidelity Scale
Steve Hall, Ph.D., Director of Employment Policy and Research, Griffin-Hammis Associates


The Discovery Fidelity Scale (DFS) was created to improve the quality of Discovery, the initial process of Customized Employment.  The DFS has both Systems and Services tenets from a consensus of experts and experienced practitioners of Discovery and Customized Employment.  Tenets include:  Authorization and Access, Financing, and Discovery Providers Systems Tenets. Home and Area Visits, Discovery Activities, Informational Interviews, Vocational Profile Narrative Review, and the Employment Plan are the Services Tenets.

Research on the development of the DFS has been accepted for publication by the Journal of Vocational Rehabilitation. The reliability and validity of the DFS is being further improved through field implementation in California and Utah during 2018 and 2019, and in additional States during 2019.  A Job Development Fidelity Scale (JDFS) is being developed at this time to improve the quality of Customized Job Development for persons with significant disabilities.
