Qualifications

While the ADA does not mandate any specific credentials for working interpreters, with the exception of some states and territories that have minimum requirements for interpreters to work in specific settings, the ADA does mandate the use of "qualified interpreters." Qualifying interpreters could be certified and/or have the right education, experience, and content knowledge for a particular job, but certification doesn't guarantee qualification for every job. Additionally, there are "substantial barriers to obtaining certification for historically marginalized groups." Employers use various measures and factors to determine whether the interpreter meets ADA's definition of qualified; measures can include education, experience, certification, assessments, licensure, and other regulatory mandates on a state-by-state basis.
