<em>The implementation of diversity management becomes a challenge for the company specially to employ those with physical disabilities. There is a stereotype in Indonesian society that those people are not able to work, especially in the formal sector due to their lack of competences that results in their low performance. Unfortunately, studies regarding the effect of competency towards employee performance of employees with disabilities has been very limited. This study aims at determining the influence of competency towards the performance of employees with disabilities in Thisable Enterprise. Data was conducted through a survey of 64 employees who are blind and deaf. Furthermore, the hypothesis test was carried out using multiple linear regression analysis with SPSS 24.0 software.
