• Confirm that the vendor is fully compliant with FERPA and has SOC 2 Type II certification. You should also review the data processing agreement to understand how student data is handled. Without these safeguards, the district risks data breaches and resulting legal liabilities.

5.4 Alignment with Curriculum Goals

• Ensure that the data warehouse's reporting aligns with your district's curriculum standards. For example, if you use the International Baccalaureate framework, the system should support its specific proficiency scales. A mismatch here would require costly custom report development.

5.5 Long-term Scalability and Support

• Evaluate the vendor's roadmap for data storage and processing capacity. Request a demonstration of the system's ability to handle a three-year projection of data growth. Without scalability, the system will become a bottleneck as data volumes increase, degrading performance and user satisfaction.

5.6 Continuous Monitoring and Feedback Loop

• After implementation, establish a quarterly review cadence with the vendor to assess system performance and user satisfaction. Use built-in analytics to track usage metrics such as login frequency and report generation. This feedback loop ensures the data warehouse remains aligned with evolving curriculum needs, converting an initial selection into a long-term strategic asset.
