For Sep 2025, the focus was on strengthening data accuracy in the TEAMSchools/teamster dashboard by correcting the Paterson region handling in pre-aggregation. Delivered a targeted SQL fix to exclude Paterson from int_topline__dashboard_aggregations, improving dashboard reliability and KPI fidelity. All changes were implemented in the TEAMSchools/teamster repository with a single commit updating the SQL script. Outcome: more trusted dashboards and reduced risk of misinformed decisions for stakeholders relying on regional performance metrics.
