How to become a certified court interpreter in Washington
Washington's Court Interpreter Program, run by the Administrative Office of the Courts in Olympia, certifies Spanish and other consortium-language interpreters through the written exam, an online orientation, and the NCSC consortium oral exam, which the AOC gives in person only twice a year. Languages without a consortium exam use a Registered pathway with an English test and an OPI instead. Certification ends with a fingerprint background check, the interpreter's oath, and ongoing continuing education and courtroom hours.

Steps to certification in Washington
- 1
Pass the NCSC written exam
The written exam is 135 multiple-choice questions on English proficiency, court terminology and ethics, computer based and available year round at testing centers across the state. The AOC's written exam overview lists the registration fee at $91 (an older 2013 form said $75), non-refundable. The passing score is not stated on the pages we reached; consortium states generally use 80%.

Complete the online orientation
After you pass the written exam the AOC invites you to a virtual orientation covering the structure and terminology of Washington courts, criminal procedure, the modes of interpreting and an overview of the oral exam. You must finish orientation before you can register for the oral exam.

Practice for at least six months before the oral exam
The AOC's own guidance is to expect six or more months of preparation after the written exam. The oral exam has four parts: sight translation English to Spanish and Spanish to English (about 225 words, six minutes each), consecutive interpreting with up to two repeats, and a simultaneous passage of 800 to 850 words at about 120 words per minute. Raters count scoring units. The AOC publishes a self-assessment form and a study resources page that names outside training providers; for graded audio practice at exam pace, CourtFluent's daily drills follow the same consortium format.

Take the oral exam (70% on each section), offered twice a year
Certified-language oral exams are in-person, proctored sittings held twice a year, most recently at Highline College: April 25 to 26, 2026 and October 24 to 25, 2026 (both tentative when posted). Fill out the AOC's oral exam interest form to be notified when registration opens. You need at least 70% on each section. The oral exam fee is not published on the pages we could reach; prior research cited $75 (unverified).

Background check, application fee, oath and credential
After passing, submit a completed fingerprint card and the application fee to the AOC, pass the Washington State background check, and take the interpreter's oath at a ceremony. The AOC then issues the credential and lists you on the certified interpreter roster.

Maintain certification
Staying on the active roster requires continuing education credits, a set number of courtroom interpreting hours, and a personal conduct declaration on a two-year cycle. The specific credit and hour counts are on the AOC's certified interpreter pages, which we could not load; confirm them with the program before your first renewal.
When Washington holds the exams
The written exam is available year round at testing centers. The certified-language oral exam runs twice a year; the 2026 sittings were posted as April 25 to 26 and October 24 to 25 at Highline College, tentative. Registration opens by email to people who submit the AOC's oral exam interest form. Registered-language OPIs are available year round through the testing vendor.

Washington certification questions
Do I need to be certified to work in Washington courts?
RCW 2.43 requires courts to appoint a certified interpreter for certified languages such as Spanish unless good cause is found on the record, so uncredentialed Spanish interpreters get little court work. Registered status covers languages with no certification exam.
How many times can I take the Washington oral exam?
No lifetime cap is published, but with only two sittings a year each retake costs at least six months. Check the testing and training page for any waiting-period rule in effect.
Does Washington accept another state's certification (reciprocity)?
Washington recognizes certification from other consortium states and federal certification, subject to the AOC's review of your score report, Washington orientation, the background check and the oath. Contact the program with your documents before assuming your scores transfer.
How long does certification take?
The written exam can be done any time. With the AOC's recommended six months of preparation and two oral sittings a year, a first-attempt pass takes about a year; most candidates need a second sitting, so 18 months is common.
What does the Washington oral exam consist of?
The NCSC consortium exam in four parts: two sight translations, consecutive interpreting and simultaneous interpreting, scored on scoring units with a 70% minimum on each section. The AOC's oral exam overview describes each part in detail.
