This dashboard provides:

• Skill Heatmaps — per student, per topic
• Class Performance Comparison
• PTM SAS Band Distribution
• PTM Progress Tracking Over Time
• Test Completion Analysis
• Question & Curriculum Analysis
• Key Findings (per class)

I found the skill heatmaps and skill summaries to be the most important, along with the hardest questions section.

Please pay close attention to the Key Findings section for your class.
