Certifications are important for sign language interpreters because they demonstrate a level of proficiency and professionalism in the field. They give employers assurance that the interpreter is qualified to do the job and can provide quality services. Having certifications also allows interpreters to prove their qualifications, which can be a deciding factor when employers are selecting from a pool of applicants. Additionally, certifications may provide interpreters with access to higher-paying jobs or better job opportunities.

The purpose of this article is to review some of the top certifications for Sign Language Interpreters and explain how they can contribute to a sign language interpreter's career.

What are Sign Language Interpreter Certifications?

Sign language interpreter certification is a process that ensures interpreters have the necessary knowledge, skills and abilities to provide quality interpreting services. The National Association of the Deaf (NAD) has established a formal certification program for sign language interpreters that provides recognition of individuals who have met certain criteria in terms of education, experience and performance. This certification is important because it helps ensure that deaf individuals are able to access accurate communication with hearing people.

The NAD’s certification process includes an examination that assesses an individual’s knowledge of American Sign Language (ASL), English fluency, culture, code of ethics, and other relevant topics. Additionally, applicants must demonstrate their interpreting skills by completing a written exam, role-play scenarios and video recordings of real-life interpreting situations. The NAD also requires interpreters to complete continuing education requirements on an annual basis in order to maintain their certification.

Having a certified interpreter can help make sure that conversations between deaf and hearing individuals are clear, effective and meaningful. Certified interpreters are knowledgeable about ASL grammar and syntax as well as cultural norms and etiquette which allows them to provide accurate interpretations between the two languages. Furthermore, certified interpreters are required to adhere to the NAD Code of Professional Conduct which sets standards for professional behavior such as confidentiality and respect for all parties involved in the interpretation session.

Overall, sign language interpreter certification is essential in helping ensure quality communication between deaf individuals and hearing people. It not only verifies an interpreter’s knowledge but also demonstrates their commitment to providing ethical services for all parties involved in the interpretation session.

Pro Tip: Make sure to get certified in the specific sign language that you plan on interpreting. Different sign languages have different rules and conventions, and it’s important to be knowledgeable of the specific language you will be interpreting. Additionally, make sure to keep your certification up-to-date by taking refresher courses or attending workshops regularly.
