Tongan is the main language of daily life, culture, public participation and Legislative Assembly proceedings in Tonga. English provides parallel access to education, legal materials, government work and international communication. Tonga has not been shown to have a single general official-language clause covering every public service, so the language used depends on the institution and purpose. The 2021 Tonga Statistics Department census recorded that, among people aged five and over, 96% could read a simple sentence in Tongan and 89% could do so in English. These figures describe literacy, not everyone’s language use or first language. Education follows a planned progression: early childhood education and Classes 1 to 3 use mainly Tongan, Classes 4 to 6 use both languages, and English becomes the main teaching language from Class 7. Schools continue teaching Tongan through Form 7. The Tonga Education Sector Policy Framework 2025–2035 proposes a revised language policy, but that policy was still under review rather than approved. The Education Act requires education and vocational information to be available in Tongan and English. Government materials, such as tax identification registration forms, can also be bilingual. No general right to receive every government service in either language, and no separate language-access fee, has been established in the available sources. The Interpretation Act provides that the Tongan version of a law prevails when the two language versions differ, except for a simple clerical or translation error. Niuafoʻou is specifically identified as a local language requiring preservation. Tongan and Niuafoʻou learning and reading materials are supported, while no reliable current official map or classification of all Tongan dialects and minority languages has been identified. Tonga Broadcasting Commission provides national broadcasting, and its website uses Tongan and English. Bilingual education, public information, parliamentary consultations and media access therefore support participation, including for people living on remote islands through print, radio, online and blended formats.
