Each year AMS publishes a state-of-practice report on court interpreting in California. This 2026 edition compiles the latest publicly-available data on certified language coverage, federal court interpreter availability, professional teaming standards, the indigenous-language gap that surfaces in immigration and criminal-defense work, and what is changing in California court interpreting policy this year. Sources for every claim are linked at the end of each section. Writers, journalists, academics, and compliance professionals are welcome to cite this report.

Executive summary

The California Court Interpreter Program (CCIP) certifies court interpreters in 12 spoken languages plus American Sign Language (ASL). The 12 spoken languages are Arabic, Armenian (Eastern and Western counted as one program with two variants), Cantonese, Farsi, Khmer, Korean, Mandarin, Portuguese, Punjabi, Russian, Spanish, and Vietnamese.
For languages outside the 12-certified list, California uses the Registered Court Interpreter category. The Judicial Council maintains the master roster.
At the federal level, only three languages have FCICE certification: Spanish, Haitian Creole, and Navajo. All other federal court interpretation uses professionally-qualified interpreters.
NAJIT teaming standards recommend a two-interpreter team for any proceeding expected to run over one hour. California courts increasingly require this for multi-day trials.
The most significant gap in California court interpreting in 2026 remains indigenous Mesoamerican languages. Mam, Quiché, Mixteco, Triqui, and Zapoteco speakers continue to surface in California proceedings without qualified in-language interpretation.

Section 1. The certified-language roster

The California Court Interpreter Program (CCIP), administered by the Judicial Council of California, maintains the state's certified court interpreter roster. As of the most recent CCIP publication, certification is available in 12 spoken languages plus American Sign Language. The 12 spoken languages include the largest immigrant-origin language communities in California: Spanish, Mandarin and Cantonese Chinese, Korean, Vietnamese, Tagalog (no, Tagalog is not currently certified; Filipino-American legal matters use the Registered category), Armenian (Eastern and Western), Farsi, Khmer, Punjabi, Russian, Arabic, and Portuguese.

A certified court interpreter has passed a state-administered examination testing simultaneous, consecutive, and sight-translation skills under timed conditions. The exam is rigorous; pass rates for some language pairs have historically been low. As a result, the certified pool is meaningfully smaller than the population that practices court interpretation in California.

Section 2. The Registered Court Interpreter category

For languages where a certification examination does not exist, California uses the Registered Court Interpreter category. Registered interpreters are listed on a Judicial Council-maintained roster after meeting documented training and experience requirements. The Registered pathway covers many languages including Tagalog, Japanese, Hindi, Urdu, Hebrew, French, German, and dozens of others where the speaker population in California is significant but smaller than the certified-language tier.

Registered Court Interpreters are appropriate for state court proceedings in their listed languages. For the rarest languages where neither certified nor registered interpreters are available, courts use the Provisionally Qualified category, with the qualification documented on the record at each proceeding.

Section 3. Federal court interpretation

The Federal Court Interpreter Certification Examination (FCICE), administered by the Administrative Office of the U.S. Courts, certifies federal court interpreters in three languages: Spanish, Haitian Creole, and Navajo. All other federal court interpretation in California uses interpreters classified as "professionally qualified" or "language skilled" by the AOUSC. Federal courts do not require state certification, but in practice California state-certified interpreters are routinely assigned to federal proceedings because of the depth of their training.

California has four U.S. District Courts: Central District (Los Angeles), Northern District (San Francisco and Oakland), Southern District (San Diego), and Eastern District (Sacramento, Fresno). Each generates substantial federal interpretation demand. The Central District is the busiest, particularly for immigration-related criminal cases at the U.S. District Court at the Roybal Federal Building in downtown LA.

Section 4. The NAJIT teaming standard

The National Association of Judicial Interpreters and Translators (NAJIT) recommends a two-interpreter team for any court proceeding expected to run over one hour. The recommendation reflects research on cognitive fatigue: interpreter accuracy declines measurably past the first hour, with steeper declines past 90 minutes. Teamed pairs rotate every 20 to 30 minutes and check each other's work on the record.

California superior courts and the U.S. District Courts in California increasingly schedule multi-day proceedings (trials, lengthy depositions, sentencing hearings) with teamed interpretation. The cost roughly doubles, but the accuracy improvement is material. Defense counsel and civil litigators should budget for teaming when scheduling proceedings longer than an hour.

Section 5. The indigenous Mesoamerican language gap

The most significant gap in California court interpreting in 2026 remains indigenous Mesoamerican languages. Speakers of Mam, Quiché (K'iche'), Q'eqchi', Mixteco, Triqui, Zapoteco, Náhuatl, and other indigenous languages continue to surface in California proceedings as criminal defendants, civil witnesses, asylum applicants, and workers-comp claimants. Many are misclassified as Spanish speakers because they have working Spanish as a second or third language, but their first-language testimony is significantly different.

The qualified indigenous-language interpreter pool in California is small (a few dozen working interpreters across all languages combined, mostly concentrated in the Central Valley, Oakland-Fruitvale, and Los Angeles's Pico-Union). For most proceedings, indigenous-language interpretation is provided via vetted remote video, often connecting interpreters in Oaxaca, Guatemala, or U.S. enclaves to the California venue.

Federal courts and California superior courts have improved their identification of first-language indigenous speakers over the past decade, but identification at intake is still inconsistent. Defense counsel and asylum attorneys should affirmatively ask any witness from southern Mexico or highland Guatemala about their first language at the earliest opportunity.

AMS's position: this gap is the highest-priority improvement opportunity for California court interpreting policy. Investment in identification at intake and a structured remote-interpretation network for indigenous languages would substantially improve due process for affected communities.

Section 6. What is changing in 2026

Continued growth in remote depositions and remote court appearances under California Code of Civil Procedure provisions allowing video proceedings. Most California-based depositions now offer a remote option; interpretation supports this routinely.
Increased AME and QME volume in workers-compensation proceedings as California's post-pandemic claim backlog clears. Spanish, Vietnamese, Korean, and Tagalog are the highest-volume workers-comp languages.
Continuing growth in language-access compliance scrutiny under Section 1557 of the Affordable Care Act, particularly for Medi-Cal-contracted providers and federally-funded healthcare systems. The 2024 Final Rule updated language-access expectations for telehealth.
AI-assisted interpretation tools entering the market. As of 2026, these tools are not yet at the accuracy level required for legal or medical interpretation but are being piloted for limited administrative settings (intake interviews, scheduling calls). AMS's position is that legal and medical interpretation will remain human work for the foreseeable future.
Ongoing federal court emphasis on interpreter quality after recent appellate decisions in the Ninth Circuit highlighting Sixth Amendment Confrontation Clause concerns in criminal cases with substandard interpretation.

Section 7. Practical recommendations for 2026

For California state court proceedings: use CCIP-certified interpreters where the language is on the 12-language list. For languages off the list, use Registered interpreters.
For federal court proceedings: use FCICE-certified interpreters for Spanish, Haitian Creole, and Navajo. For other languages, use AOUSC professionally-qualified interpreters.
For proceedings expected to run over an hour: budget for teamed interpretation (two interpreters rotating every 20 to 30 minutes).
For witnesses from southern Mexico or highland Guatemala: ask about first language before assuming Spanish is appropriate. Indigenous-language interpretation produces materially better testimony.
For medical proceedings in covered healthcare settings: confirm Section 1557 compliance and qualified medical interpreter use. The 2024 Final Rule applies.
For workers-comp depositions and WCAB hearings: use court-certified interpreters where the language is on the CCIP list. Workers-comp procedural cadence requires interpreter familiarity with AME, QME, AOE/COE, and panel-QME terminology.
