Information about Other Credentials
Federal and State Courts: Federal and State courts have mechanisms to qualify interpreters for whose languages have not language-specific certification test. Federal courts have three classifications: “certified,” “professionally qualified,” and “language skilled.” Each category has its own requirements. State courts vary in how they categorize interpreters whose languages do not have a specific test. For example, California has “certified,” “registered,” and “provisionally qualified” interpreters. To learn about your state’s specific requirements, we recommend that you google “[your state] court interpreter certification program” or search this map of state court certification programs.

The State Department has three levels of interpreter: liaison, seminar, and conference. Learn about the U.S. State Department’s interpreter and translator credential.
United Nations: As with the State Department, the U.N. tests “language professionals” to qualify them to work for the U.N. and not as a certification per se. Learn about the United Nation’s testing process.
