This article is based on the findings of a piece of documentary research funded by the Centre de recherche sur les politiques en matière d’invalidité professionnelle (CRPIP) examining the processes and instruments around the measurement of disability by various components of public services. This implementation research looks at the state of knowledge with respect to the instruments and modalities used to evaluate work capabilities as applied by public assistance plans, including the Québec plan. In this article, a few of the findings of this research on the characteristics of the employability evaluation process applied by the Québec public assistance plan (social assistance) are presented. Evaluating employability refers to identifying the employment limitations and barriers that assisted individuals face. In Québec, this process involves two parallel pathways, namely: (1) Evaluating the constraints related to state of health based on the permanent (or non-permanent) nature of limitations; and (2) Investigating other employment barriers/limitations. This second stream forms part of the entrevue d’évaluation et d’aide à l’emploi (SAEE) [employment evaluation and support interview] and is based on a predetermined list of barriers related to four areas of competence. The research showed that the evaluation of health-related disabilities is conducted from the perspective of verifying eligibility for a benefit or financial support program, while the evaluation of other disabilities is conducted from the perspective of devising a service plan designed to help strengthen the longterm employment prospects of those requesting assistance.
