Substitute Senate Bill No. 1391 seeks 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 sharing this data with public institutions of higher education. Additionally, the bill revises section 10-17o to establish a written bill of rights for parents or guardians of multilingual learners, ensuring their rights are protected in bilingual education, including the right to enroll students without immigration documentation, access translation services, and receive information about their child's educational progress. The proposed legislation also introduces new rights for parents, such as the right 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 aim to enhance educational outcomes and support for multilingual learners and their families. Importantly, the bill is not expected to impose any fiscal impact on the state or municipalities, as the changes will not affect the costs associated with the State Department of Education's data collection or reporting responsibilities. The bill has garnered unanimous support from the Education Committee, highlighting a strong consensus on the need for improved data transparency for multilingual learners in Connecticut's educational system.
