THECB data team demos T3 dashboard and state data tools, highlights Sankey visualizations and masking rules
Summary
The Coordinating Board’s data team demonstrated T3 — an interactive eighth‑grade cohort-to‑postsecondary dashboard — and described state data resources (Data Bridge, Accountability). The T3 tool uses Sankey diagrams, includes National Student Clearinghouse data and masks small cell counts to protect privacy.
Sharon Wong, assistant director in the Coordinating Board’s Data Management and Research division, and Brian Cordo, deputy assistant commissioner for data management research, demonstrated the T3 dashboard and related state data tools for the FAAC.
Wong said T3 converts the Coordinating Board’s historical eighth‑grade cohort report into an interactive Power BI dashboard that tracks students from eighth grade through six years after high‑school graduation. “Our ultimate goal is to empower educators, policymakers, and stakeholders to make data driven insights and support informed decision making,” Wong said.
Key features Wong demonstrated included region/district/campus filters, downloadable statewide summaries, year‑over‑year comparisons and Sankey flow diagrams that visualize student transitions (for example, the flow from eighth grade to high school completion to enrollment in two‑ or four‑year institutions and final credential). Wong cautioned the dashboard does not show every possible pathway (for example, transfers between institutions are not visualized) and that T3 suppresses or masks aggregate counts under five for FERPA/privacy protection.
Wong described the roadmap for T3: add the 2014 eighth‑grade cohort, migrate backend data to a cloud data warehouse rather than CSV files, and add out‑of‑state enrollment and degree data (the dashboard already uses National Student Clearinghouse data for out‑of‑state enrollment in some views). She also walked committee members through the dashboard appendix, which provides variable definitions and FAQs.
Cordo followed with a wider tour of national and state data resources. He covered the federal College Scorecard and College Navigator tools and the IPEDS data feedback report (a fast way to produce peer comparisons), and highlighted the coordinating board’s Data Bridge and Accountability sites for enrollment and completion data. Cordo demonstrated how IPEDS’ data‑feedback report can be used to generate downloadable peer‑comparison PDFs and noted Scorecard’s API and field‑of‑study filtering.
Both presenters urged FAAC members to use the public dashboards, download appendix materials for methodology, and contact the data team with questions. Wong said the T3 team will continue iterative improvements and is accepting feedback.
