Who needs language services in Seattle

Citywide language access plans
Executive Order 2017-10 requires every city department to create a language access plan built on the U.S. Department of Justice four-factor analysis and submit it to the Office of Immigrant and Refugee Affairs (OIRA) every two years, and the Seattle Office for Civil Rights investigates language-access complaints.[1]
City translation and interpretation
The city translates vital documents mainly through a team of Puget Sound-based independent contract linguists whose contracts OIRA manages, uses multiple vendors for phone, video, and on-site interpretation, and requires departments to post translated notices of free language assistance at entrances, lobbies, websites, and kiosks.[1]
Top languages without tiers
OIRA dropped its tier system in its 2023 top-languages report, asks departments to choose languages by community need, recommends Traditional Chinese for written materials and both Cantonese and Mandarin for interpretation, and updates the ranking every three years.[2]
Newly arrived residents
For recent immigrants and refugees, OIRA points departments to refugee screening and state data: 16,739 Ukrainians arrived in Washington and received state services between January 2022 and February 2023, and more than 3,200 Afghans have arrived since October 2021.[2]
Seattle Municipal Court
The court's language access plan (effective August 1, 2025) lists 13 current needs (Spanish, Vietnamese, Somali, Amharic, Mandarin, Korean, Tigrinya, Punjabi, Cantonese, Arabic, Samoan, Swahili, and Khmer), appoints credentialed interpreters whenever possible, documents good cause when it cannot, and does not use automated translation for official court communications.[3]
Seattle Public Schools
Under Policy 4218 (revised October 2022), the district provides free translation and interpretation in Amharic, Chinese, Somali, Spanish, and Vietnamese and contracts for over-the-phone interpretation in other languages, requested through each school.[5]
King County language access law
King County Code Chapter 2.15 requires county agencies to keep language assistance plans naming the vital documents and public materials they translate into the county's top six languages, and to provide language assistance at no cost and without unreasonable delay.[6]

Language access rules in Washington

Court interpreter program
Washington Administrative Office of the Courts (AOC) Language Access Team, which supports the courts' language access work; the AOC credentials spoken-language court interpreters under RCW 2.43.070, General Rule 11 establishes the Interpreter and Language Access Commission (ILAC), and local trial courts schedule interpreters.
Court-certified languages
As of September 2026 the AOC lists certified court interpreters in 16 languages (Amharic, Arabic, Bosnian/Croatian/Serbian, Cantonese, French, Haitian Creole, Hmong, Khmer, Korean, Mandarin, Portuguese, Russian, Spanish, Tagalog, Turkish, and Vietnamese) and registered interpreters in 38 languages (several overlapping with the certified list), from Albanian, Dari, and Farsi to Somali, Tigrinya, Ukrainian, and Yoruba.
The rule
RCW 2.43.030, as amended in 2025, requires credentialed interpreters to be appointed in any legal proceeding involving a person with limited English proficiency, in court or before a state or local agency, unless good cause is found on the record; RCW 2.43.081 makes an LEP person not responsible for interpreter costs if a party, subpoenaed or summoned, a juvenile's parent, guardian, or custodian, or compelled to appear, and RCW 2.42.120 requires the appointing authority to appoint and pay for a qualified interpreter for deaf and hard of hearing parties and witnesses.
Court language access plans
RCW 2.43.090 requires every trial court to maintain a written language access plan covering civil and criminal matters, including procedures for appointing interpreters, posting notice of the right to an interpreter in the five or more non-English languages predominant in the jurisdiction, and prioritizing translation of written materials.
School district language access programs
Under RCW 28A.183.040 (2022 c 107), every school district must designate a language access liaison, adopt a language access policy and procedures, and since the 2023-24 school year implement a language access program for family engagement; RCW 28A.183.050 requires districts to collect each family's preferred language and whether a qualified interpreter was requested and provided at meetings reported to the state longitudinal student data system.
Public assistance interpreters
RCW 74.04.025 requires the Department of Social and Health Services, the Health Care Authority, and the Office of Administrative Hearings to provide bilingual services so non-English-speaking applicants are not denied benefits, using contracts with language access providers where staff cannot cover the need, and requires DSHS to certify, authorize, and qualify those providers through oral and written testing.
School interpreter credentialing
RCW 28A.183.080 directs the Office of Superintendent of Public Instruction and the Professional Educator Standards Board to establish credentialing requirements for school interpreters, in consultation with the state language access advisory committee.
Who pays in agency proceedings
Under RCW 2.43.081, when a legal proceeding is initiated by a government agency, the governmental body that initiated it bears the cost of the interpreter.
