June 2026 monthly summary for TEAMSchools/teamster: Key work focused on making analytics time-aware, governance-aligned, and production-stable. Highlights include Cube snapshot enhancements with an anchor guard and CA/truancy measures, AY labeling, and the integration of academic_year_label into dim_dates with exposure in attendance views, supported by updated tests and documentation. Significant stability and correctness improvements were achieved through fixes such as suppressing sqlfluff LT01 in is_week_end_record, reworking the enrollment/attendance spine with a boundary-union approach, and routing attendance status through the enrollment-grain rollup. Additional impact came from DBT and cube semantic-layer expansion (administration_dates, assessments, and student_assessments cubes; student_enrollment_status), plus tooling and playbook improvements for dev/test workflows. Overall impact: higher data quality, more reliable year-over-year analytics, and a scalable foundation for evolving academic-year semantics across dashboards, APIs, and analysts’ workflows.

Monthly summary for 2026-05 focusing on business value and technical achievements across TEAMSchools/teamster: Key features delivered and major fixes: - Admin Directory API: Correct scope for groups lookup fixed to ensure proper access when listing user groups (admin.directory.group.readonly for groups.list). This prevents unauthorized access and aligns with Admin SDK permissions, reducing risk of failed group lookups in cube features. - Attendance data model and CA metrics: Added chronic absenteeism and ADA tier to the attendance fact; restructured fct_student_attendance_daily with CTEs to expose running sums and is_chronically_absent and ada_tier; introduced enroll_status filtering to CA metrics to align with Tableau, and updated related measures (pct_tardy, pct_ontime) for accuracy across dashboards. - Attendance cube exposure and governance: Exposed attendance cube members publicly for view access across related cubes (attendance, attendance_detail, dim_dates), and updated view exposure in joined cubes to ensure dashboards can safely read current data without exposing sensitive joins. - Lattice extracts improvements: Updated Lattice user roster filter and SFTP path for extracts; expanded inclusion criteria (Terminated staff with 30-day lookback, specific titles/locations) and updated destination path to production, improving data timeliness and completeness for HR analytics. - Point-in-time dimensional enhancements: Added point-in-time dims for ELL, IEP, and meals to attendance-related views; replaced current-state attributes with dimensional history to support accurate year-long reporting and cross-report consistency. Major bugs fixed and stability improvements: - Admin Directory API categories: Correct scope usage prevented mispermissions in groups lookup. - Attendance: Ensured visibility and consistent access across attendance-related cubes; fixed public exposure and joined cube access to avoid misreads in dashboards. - Lattice roster extraction: Corrected intern filtering and roster scope to produce accurate headcount in downstream analytics. Overall impact and business value: - Improved data correctness, access governance, and dashboard reliability, enabling faster decision making and more trustworthy analytics for student performance, CA compliance, and HR operations. - Reduced risk of permission errors and data leakage by aligning scopes and exposure with intended access policies. - Increased data timeliness and coverage for population analytics (Lattice, attendance, and roster extracts), supporting better workforce planning and policy evaluation. Technologies and skills demonstrated: - Cloud-based data stack and BI integration (DBT, cube, Cloud Run concepts via MCP docs), SQL optimization, and data modeling (attendance_fact, dim tables, and running windows). - Version control discipline (co-authored commits across multiple features and fixes). - Data governance and documentation practices, including scope clarification and design specs for MCP deployments and access controls. - Collaborative development across squads, with robust test and validation patterns for complex join paths and date-range semantics.

Month: 2025-05 focused on correcting teammate name representation in reporting for the TEAMSchools/teamster repo. Implemented a SQL query refactor to consistently use the current teammate name across all records. Removed the legacy teammate field from the initial SELECT and re-added it in subsequent sections to ensure the most up-to-date name is reflected. This standardization improves data integrity for teammate-based metrics in downstream dashboards and reports. Resulted in more trustworthy analytics, reduced need for manual data cleaning, and smoother reporting cycles. Technical approach prioritized minimal risk by isolating the change to the data extraction path and validating against existing reporting queries.
