Reason Diagnostic Testing

Begin the year with a clear picture of every learner. Reason’s adaptive diagnostic responds to student progress, accuracy and the strategy demonstrated — building a detailed learning profile and suggested starting level for every mathematics unit.

Understand your class from the first lesson, establish a meaningful baseline and track student progress across the year with consistent evidence.

  • Adaptive question pathways
  • Accuracy and strategy analysed
  • Suggested level for every unit
  • A baseline for year-long growth
