MTSS Decision Protocol Flowchart
MTSS / RTI Protocol Progress Monitoring Decision Tree
MTSS Response to Intervention Flowchart
Tier II & Tier III Data Decisions Rate of Improvement (ROI)
Typical ROI: Expected peer growth rate
Target ROI: Rate needed to close gap
Attained ROI: Student's actual measured slope
Starting Condition
Student is receiving an MTSS intervention
Core Diagnostic Question 1
Is intervention being implemented with fidelity and for sufficient time?
(Minimum 6–8 data points / regular scheduled sessions verified)
NO Implementation Gap
Address fidelity/implementation first. Ensure correct group size, dosage, program materials, and attendance before changing tiers.
Verify & Retest
YES Calculate Rates of Improvement
Slope Analysis
Typical ROI Benchmark Norm
Target ROI Catch-Up Slope
Attained ROI Student Progress
Is student making positive growth?
NO Little / No Response
Revisit hypothesis & intensify or change intervention approach immediately.
YES Compare Slopes
Attained ≥ Target: Closing gap rapidly
On Track
Typical ≤ Attained < Target: Growing, not closing
Adjust
2 Longitudinal Gap & System Decision
Evaluated after full intervention cycle
Is the student still substantially below benchmark?
NO Gap Closed
Monitor progress & consider fading MTSS support. Transition toward maintenance in Tier I with periodic checks.
YES Is gap closing at an adequate rate?
YES: Adequate Gap Closing
Continue current targeted support and maintain weekly/bi-weekly progress monitoring.
NO: Inadequate Rate
Intensify/modify MTSS (increase dosage, reduce group size) and conduct problem-solving.
Evaluation Decision Point
Multi-Disciplinary Team Review
After appropriate intensified support, is student response still inadequate?
NO — Response Showing Progress
Continue MTSS Tier II/III with rigorous progress monitoring and iterative instructional adjustments.
YES — Dual Discrepancy Met
Consider comprehensive evaluation for Specialized Education Services (IDEA/Section 504), consistent with district criteria and data.
Team Checklist: ✓ 6–8 Data Points ✓ Fidelity Logs Verified ✓ Dual Discrepancy Analyzed (Level + Slope)
