MTSS (Multi-Tiered System of Support) in reading is a framework that provides tiered instruction, including core instruction (Tier 1), targeted small group interventions (Tier 2), and intensive support (Tier 3), based on student needs.
Why Your MTSS Reading System Isn’t Working (And How to Fix It)
Your MTSS framework might look strong on paper. But is it improving outcomes? In many districts, the answer is no.
The Core Problem
MTSS often fails due to:
• weak Tier 1 instruction
• inconsistent intervention practices
• lack of data-driven decision making
According to National Center on Response to Intervention, Tier 1 instruction is the most critical component of MTSS success.
What Strong MTSS Looks Like
Effective systems include:
• strong core instruction
• targeted Tier 2 interventions
• intensive Tier 3 support
• consistent progress monitoring
Why Implementation Breaks Down
Without coaching, teachers struggle to:
• align instruction to student needs
• monitor progress effectively
• adjust interventions
The Fix
Districts must:
• strengthen Tier 1 instruction first
• use diagnostic data
• provide coaching support
How CSAS Helps
CSAS supports MTSS systems by:
• aligning instruction across tiers
• strengthening intervention practices
• building teacher capacity
Final Thought
MTSS doesn’t fail. Implementation does.
