Legal Interpreters: How to Understand Their Qualifications

For individuals who are limited English proficient (LEP) or Deaf/hard-of-hearing and need to participate in a court hearing, they have the right to an interpreter in federal, state, and local courts. An interpreter is required to protect one’s basic constitutional rights by providing equal language access.

A legal interpreter plays a critical role in the court process, serving as the bridge between non-English-speaking individuals and English-speaking participants. An interpreter must interpret the content without editing, summarizing, deleting, or otherwise modifying the content. They must be impartial and able to serve the judicial process as required.

In this blog, we’ll look at some of the legal interpreter qualifications and requirements used in the legal system. Understanding a legal interpreter’s qualifications is crucial for ensuring accurate communication in court, protecting constitutional rights, and avoiding errors that could affect case outcomes.

Federal Legal Interpreter Qualifications

The federal government recognizes three types of legal interpreters.

Federally Certified Legal Interpreter

A federally certified interpreter has passed the Administrative Office certification exam. These exams are only available for Spanish, Navajo, and Haitian Creole interpreters. The local federal court will determine if an interpreter is professionally qualified or has the language skills for other languages.

Professionally Qualified Legal Interpreter

This designation is for all languages except Spanish, Navajo, and Haitian Creole. A professionally qualified interpreter meets the criteria for this designation. The criteria consider areas like tests and assessments, memberships, and other certifications.

Language Skilled / Ad Hoc Legal Interpreters

A language-skilled / ad hoc interpreter demonstrates the ability to interpret court proceedings to the court’s satisfaction, but isn’t a professionally qualified interpreter. While using a language-skilled / ad hoc interpreter is not always appropriate, it may be acceptable in some cases.

State Legal Interpreters

Each state has its own legal interpreter requirements. As an example, the state of California recognizes two types of interpreters:

  1. Certified court interpreters – these interpreters have passed a written exam and a bilingual interpreting exam. The bilingual exam is available in 13 languages. Certified interpreters have also registered with the Judicial Council Interpreters in California.
  2. Registered court interpreters – these interpreters interpret for languages other than the 13 that are covered by the certification.

Local and National Organizations and Agencies

Local and national organizations, such as the National Association of Judiciary Interpreters and Translators (NAJIT), may provide other labels for legal interpreters, such as “conditionally approved” or “qualified.” These terms can vary a bit, but they essentially mean individuals pre-vetted by organizations, agencies, departments, or otherwise based on references, skills assessments, previous work history, an association with industry organizations, and more.

American Sign Language (ASL) Interpreters

While hundreds of sign languages exist, American Sign Language (ASL) is one of the most common types in the U.S. Currently, there’s a shortage of ASL interpreters, and some certifications can’t be tested for anymore. Nationally recognized certifications include:

Communication Access Real-Time Translation (CART)

CART, also known as real-time captioning, is a method of transcribing spoken language and sounds. The transcription is displayed on computers, mobile devices or other screens. Those who are deaf or hard-of-hearing might prefer this method. LEP individuals may also choose this method over interpreting for various reasons. CART requires reading, and it’s often a one-way communication, although some versions can incorporate two-way communication. Specialists who provide CART services can hold certifications from the Association for Court Reporters and Captioners.

Organizations that Support Interpreters and Translators

Organizations that control assessments, codes of ethics, codes of professional conduct, and more to evaluate interpreter involvement include:

The qualifications of a legal interpreter are more than just credentials—they can have real legal consequences. Courts rely on interpreters to provide accurate, impartial, and complete interpretations of proceedings, and errors or unqualified interpretations can impact case outcomes, fairness, and even appeals.

By ensuring that interpreters meet federal, state, or professional standards, courts and legal professionals can protect the fairness, accuracy, and legality of proceedings, while maintaining confidence in the judicial process.
