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.
