Substitute Senate Bill No. 1391 aims to improve the transparency and accessibility of data concerning multilingual learners in Connecticut's public schools. The bill amends section 10-10a of the general statutes to require the state-wide public school information system to track and report additional data, including the primary language spoken at home, student transcripts, attendance, and academic progress in bilingual education programs. It also mandates the collection of data on student enrollment and graduation from higher education institutions for students assigned a unique identifier, emphasizing the importance of data sharing with public institutions of higher education.

Furthermore, the bill revises section 10-17o to establish a written bill of rights for parents or guardians of multilingual learners, ensuring their rights in bilingual education are protected. This includes the right to enroll students without immigration documentation, access translation services, and receive information about their child's educational progress, along with new rights to access publicly available data on the academic progress of students in bilingual education programs. The changes are set to take effect on January 1, 2026, and are designed to enhance educational equity and support for multilingual learners and their families, without imposing any fiscal impact on the state or municipalities.
