The Connecticut State Seal of Biliteracy was established to recognize public high school graduates who have attained a level of proficiency in English and one or more languages. On June 6, 2017, the Governor signed the bill into law as Public Act 17-29. Section 1(f) of Public Act 17-29 states, “Not later than September 1, 2017, the State Board of Education shall establish criteria by which a local or regional board of education may affix the Connecticut State Seal of Biliteracy on a diploma awarded to a student who has achieved a high level of proficiency in English and one or more foreign languages. For purposes of this subsection, ‘foreign language’ means a world language other than English and includes American Sign Language and any other language spoken by a federally recognized Native American tribe.” The Connecticut State Department of Education (CSDE) encourages district participation in this initiative.
