TX HB3963

Establishes an early childhood integrated data system to facilitate sharing of data across state agencies serving young children, with the Texas Education Agency (TEA) serving as the lead agency responsible for implementation and maintenance

Requires cooperation among four key entities: the Children's Learning Institute at UT Health Science Center Houston, Health and Human Services Commission, Texas Education Agency, and Texas Workforce Commission, with each required to enter memoranda of understanding for data sharing

Mandates the system integrate existing state and federal data to identify service gaps, align programs, report on outcome measures using aggregated non-identifying data, and comply with all privacy and cybersecurity laws

Requires TEA to submit annual progress reports to the governor and legislature by September 1, with the initial report including an interagency data governance plan, design plan, staffing status, and funding information

Sets a completion deadline of January 1, 2027, with implementation contingent on legislative appropriations; entities may use available state/federal money and accept gifts, grants, and donations to fund the system
