Concrete formats & visuals that work

Good visuals make interpretation fast.

1. Growth chart (student-level)
   • X axis = time / assessments. Y axis = skill level or score.
   • Plot student trajectory vs. class average line.
   • Add target milestones and next steps.
2. Class histogram or density plot
   • Shows distribution of scores; instantly reveals clusters and outliers.
   • Add mean and SD markers.
3. Box plot (compact view)
   • Shows median, quartiles, outliers — great for leaders who want a snapshot.
4. Learning progression map
   • Checklist of specific skills/standards with “not yet / getting there / confident” markers for each student.
5. Item analysis table (for teachers/leaders)
   • For each test question: percent correct, common misconceptions, instructional implication.

Tip: include one short interpretation sentence under every chart.
