Language access rules in Connecticut

Court interpreter program: Connecticut Judicial Branch Interpreter and Translator Services, a centralized unit of the Superior Court Operations Division that receives and assigns interpreters statewide for each court request, using staff interpreters first, and handles the Branch's translations under the 2025 Language Access Plan.
Court-certified languages: The Branch certifies interpreters who pass an NCSC oral exam with at least 70% on each of its four sections; its interpreter page lists oral certification exams in Spanish, Portuguese, and Polish, and the 2025 Language Access Plan reports it first offered a Chinese Mandarin exam in 2025. It grants reciprocity for certification test results from Council of Language Access Coordinators member jurisdictions, treats federal court certification as Connecticut certification, and offers qualifying exams in all other languages; court-appointed interpreters must also pass a background check, an in-house orientation, and the NCSC ethics component, and be sworn in by a Superior Court judge.
The rule: The Judicial Branch's Policy Statement of Commitment Regarding Limited English Proficiency, incorporated into the 2025 Language Access Plan, cites Title VI of the Civil Rights Act of 1964 and other federal law, and the Branch provides court interpreters at no cost to limited English proficient individuals. Conn. Gen. Stat. § 51-245(d) separately requires a qualified interpreter for a deaf or hard of hearing juror throughout the proceeding and during deliberations.
Registered interpreters for deaf and hard of hearing people: Conn. Gen. Stat. § 17a-838 requires paid interpreters for deaf, deafblind, or hard of hearing people, with limited exemptions, to register annually with the Bureau of Services for Persons Who are Deaf, Deafblind or Hard of Hearing, which issues ID cards listing the settings (community, educational, legal, or medical) each interpreter is qualified for; misrepresenting registration is a class C misdemeanor.
Multilingual learner bill of rights: Conn. Gen. Stat. § 10-17o (P.A. 23-150) sets a multilingual learner bill of rights that includes a student's right to translation services, through an interpreter or a state-approved app, during parent-teacher conferences and other critical school interactions, and a parent's right to written notice of program eligibility in English and the parent's dominant language; since the 2024-25 school year each district running a bilingual or English-as-a-new-language program must give parents the bill of rights in their dominant language.
Bilingual education trigger: Conn. Gen. Stat. § 10-17f requires a school district to provide a bilingual education program the following school year whenever any one of its schools has twenty or more eligible students dominant in the same language other than English.
Interpreter privilege: Conn. Gen. Stat. § 52-146l bars an interpreter from disclosing a privileged communication made with the interpreter's assistance in any civil, criminal, legislative, or administrative proceeding unless the person who made it waives the privilege.
How courts source outside interpreters: When staff interpreters cannot cover a request, Interpreter and Translator Services turns to the Judicial Branch's contracted interpreting agencies, then to agencies under the Department of Administrative Services statewide contract, then its remote interpreting contract, and finally non-contracted agencies; since fall 2024 every case type statewide can use video remote interpreting.
Interpreting Standards Board: Conn. Gen. Stat. § 17a-835b (P.A. 25-144) created a nine-member Interpreting Standards Board within the Department of Aging and Disability Services' Bureau of Services for Persons Who are Deaf, Deafblind or Hard of Hearing to set certification requirements for interpreters in community, educational, legal, and medical settings and to recommend new standards for interpreters for deaf, deafblind, and hard of hearing people by January 1, 2027.
Most requested court languages: The Judicial Branch's 2025 Language Access Plan reports that Spanish, Portuguese, and Polish have historically been the three most requested languages, and the Branch's translated court forms are published in those three languages.
