Interpreters and translators are required to have at least 1 credential in good standing (not revoked) from one or more of the agencies or organizations listed in Chapter 14, Language Access Services of our payment policies. Interpreters must have either a Department of Social and Health Services Certification, Washington Association of the courts Certification, or a nationally recognized certificate.

Interpreters for the Deaf or Hard of Hearing

Sign interpreters are required to have certification from the Registry of Interpreters for the Deaf (RID). L&I accepts the Provisional Deaf Interpreter Credential (PDIC). Interpreters who hold this credential must submit either the National Interpreter Certification or the Certified Deaf Interpreter certification from RID following the expiration of the PDIC. 

Credentials from other organizations or states

Interpreters located outside of Washington state must submit credentials from their state Medicaid program, state or national court systems, or other nationally recognized programs. For interpreters from any geographic area, credentials submitted from agencies or organizations other than those listed in the payment policy, may be accepted if the testing criteria can be verified as meeting the minimum standards listed below. Testing must be administered by a third-party organization whose business is to conduct certification for interpreters (i.e., interpreter agency owners may not test their own interpreters). 

L&I reserves the right to review all testing and decline certification if the certificate doesn't meet the minimum criteria. 

Testing criteria

Out of state interpreter test consists of, at minimum:

  • A written test in English; and
  • A verbal test of sight translation in both English, and other tested language(s); and
  • A verbal test of consecutive interpretation in both languages.
  • For those providing services in a legal setting, a verbal test of simultaneous interpretation in both languages

    Interpreter agency owners may not test their own interpreters.
