Local language support
Local language support in Boston.
Boston runs on biotech, academia, and law — three sectors where a single mistranslated word can stop a clinical trial, derail an admission, or lose a case. Since 2007, Day Translations has supported the organizations that define the city: the Cambridge and Kendall Square biotech corridor, the Longwood Medical Area’s hospital and research networks, Harvard, MIT, and BU research teams, and the federal and state courts of Massachusetts.
Boston is also a city of immigrants. A meaningful share of residents speak a language other than English at home, with large Spanish, Portuguese, Haitian Creole, Chinese, and Vietnamese communities across East Boston, Somerville, Brockton, Chinatown, Mattapan, and Dorchester. From a graduate student translating a diploma, to a hospital serving a multilingual patient population, to a Phase III trial sponsor coordinating across 30 countries, our Boston team supports the full range of local language needs.

Certified Translation
Certified translation & document support in Boston.
Boston's certified translation demand looks different from most cities. Every fall, thousands of international students arrive at Harvard, MIT, BU, and the city's dozens of other institutions needing diplomas, transcripts, and credentials translated and certified for admissions and student-visa filings. Year-round, researchers and visiting scholars need credential and grant documentation translated for university HR and federal sponsors.
Boston's immigrant communities, from Brazilian Somerville to Haitian Mattapan, file USCIS petitions that require certified translations of birth certificates, marriage certificates, and civil records. And the city's law firms submit certified translations to Suffolk Superior Court and the U.S. District Court of Massachusetts on litigation deadlines.

A closer look at one of the most demanding categories we handle for Boston clients.
Bridging the Language Gap in Boston's Biotech Clinical Trials
In the world's leading life-sciences hub, Boston and Cambridge biotech firms are pioneering tomorrow's therapies. Bringing them to global markets demands more than scientific breakthroughs. It demands impeccable, regulatory-compliant clinical-trial translation.
Boston is not merely a city; it is an ecosystem of medical innovation. The concentration of academic institutions, research hospitals, and biotechnology startups creates an unparalleled environment for scientific discovery. According to MassBio, the Massachusetts biopharma industry is a global leader, with the Boston-Cambridge area serving as its epicenter. The journey from a Kendall Square laboratory bench to a patient’s bedside in Tokyo, Berlin, or São Paulo, however, runs through dense regulatory and linguistic terrain.
When a Boston biotech initiates a Phase III trial, it rarely confines recruitment to the United States. To hit statistical significance and enrollment timelines, trials must run multinationally — generating an enormous volume of regulated documentation. From the Clinical Trial Protocol to the Investigator's Brochure, Informed Consent Forms, and Patient-Reported Outcomes, every document must be meticulously translated. A single ambiguity in an ICF can trigger regulatory rejection, delayed timelines, and millions in lost revenue.
It is not unusual for a single global oncology or rare-disease trial originating in Boston to require translation into 25 to 32 languages — and every one of them must withstand FDA, EMA, and IRB scrutiny.
Navigating FDA and EMA Language Requirements
Both the FDA and the European Medicines Agency have explicit language requirements for clinical-trial documentation. The FDA clinical-trial guidance mandates that information provided to participants — particularly the Informed Consent Form — be in a language the subject understands; if a non-English speaker is enrolled, a certified ICF translation is required, and the translator’s qualifications and process must be documented.
Similarly, the EMA's Clinical Trials Regulation requires that documentation submitted via the Clinical Trials Information System be in the official language(s) of each Member State where the trial runs. The EMA places particular emphasis on the readability of patient-facing materials and the lay summaries of trial results, which must be translated into the local languages of all participants.
Patient-Reported Outcomes and Cognitive Debriefing
Linguistic validation is a core step in the translation of Patient-Reported Outcomes (PROs). It involves forward translation, back translation, and cognitive debriefing with native speakers in the target demographic — to confirm that the translated instrument measures the same clinical concepts as the original English version and preserves the scientific integrity of trial data.
Boston biotech firms aiming for dual FDA/EMA approval can’t treat translation as a downstream task. The most successful sponsors integrate language-service providers from protocol drafting onward, building standardized glossaries with their subject-matter experts so terminology stays consistent across every country, every submission, and every amendment.
Clinical-Trial Translation Demand by Therapeutic Area
Average number of languages required per global trial originating in Boston, by therapeutic area — illustrating why rare-disease and oncology programs concentrate the highest linguistic demand in the city.

The Longwood Medical Area: A Hub of Multilingual Research
Where Kendall Square anchors biotech corporate activity, the Longwood Medical Area is the beating heart of clinical research. Home to Harvard Medical School, Beth Israel Deaconess Medical Center, Brigham and Women’s Hospital, and (nearby) Massachusetts General Hospital, it is where theoretical science meets patient care. According to Harvard Catalyst, Boston investigators lead thousands of active clinical trials at any given time.
Local Recruitment Across a Multilingual City
Greater Boston is a city of immigrants, and a meaningful share of the population speaks a language other than English at home. To support equitable access to cutting-edge therapies, LMA researchers must provide trial information in Spanish, Portuguese, Haitian Creole, and Mandarin Chinese, among others.
Beyond local recruitment, LMA principal investigators frequently lead international multi-center trials. A PI at Dana-Farber may coordinate with sites in Paris, Tokyo, and Sydney — making rapid, accurate translation of protocol amendments, adverse-event reports, and updated consents essential for patient safety and global dataset integrity.

Need Expert Clinical-Trial Translation?
Translating Complex Protocols: Oncology and Rare Diseases
Linguistic demand varies sharply by therapeutic area. In Boston, there is heavy concentration in oncology and rare diseases — fields with their own translation challenges. Oncology trials often involve novel mechanisms (CAR-T, bispecific antibodies) whose terminology may not yet have stable target-language equivalents; translators must work alongside subject-matter experts to build standardized glossaries and lock consistent terminology across every trial document.
Rare-disease trials, with inherently small patient populations, must cast a wide geographic net to find eligible participants — averaging the highest language counts in the city. They also frequently involve pediatric populations, requiring carefully adapted Assent Forms understandable to children at varying ages, balancing medical accuracy with age-appropriate language.
Regulatory Compliance and ISO 17100 Standards
For Boston biotech, partnering with a translation provider isn't a vendor relationship — it is part of regulatory strategy. Industry leaders insist on ISO 17100-certified providers because the standard mandates rigorous translator selection, project management, and an independent reviser step. Two qualified linguists, in sequence, on every document — that's what the standard requires.
In clinical trials, that quality discipline is non-negotiable. Whether the document is a Case Report Form, an Investigator's Brochure, or a regulatory submission, the translation must be flawless. Combined with HIPAA-aligned handling of PHI and proprietary research data, ISO 17100 is what turns translation from a service into the bridge that connects Boston innovation to global health.
