“They just don’t get it.”

You’ve probably said it—or heard it—after reteaching a science concept for the third time. You’ve simplified the language, added visuals, even tried a new lab. But still, some students stare back blankly.

If this sounds familiar, you’re not alone. And more importantly, it’s not your fault.

The truth is, many students struggling in science aren’t behind because of a weak lesson—they’re behind because no one identified what type of support they really need.

Welcome to the world of Tier 3 science intervention, where the goal isn’t just to reteach…
It’s to reach—with intention, precision, and urgency.

 What Is Tier 3 Science Intervention?

In a Multi-Tiered System of Support (MTSS), Tier 3 is the most intensive level of intervention, designed for students who have not responded to Tier 1 (core instruction) and Tier 2 (small-group support).

In science, Tier 3 looks different than it does in math or reading.
Why?

Because science struggles often go unnoticed until it’s too late—when students bomb a unit test, shut down during labs, or disengage completely.

But Tier 3 students show signs earlier—if you know where to look.

 5 Early Signs a Student Needs Tier 3 Science Intervention

1. Consistent Struggles With Foundational Concepts

Students repeatedly confuse core concepts like mass vs. weight, or chemical vs. physical change—even after reteaching. This signals conceptual misunderstanding, not simple forgetfulness.

👩‍🏫 Real Talk: I once had a student confuse atoms and cells for half the year—until we slowed down and used an anchor chart comparison to separate the two.

2. Limited Academic Vocabulary

They can’t explain phenomena because they don’t have the language. You’ll hear “that thingy” instead of “condensation” or “energy,” and vague responses instead of precise terms.

✅ Best Practice: Incorporate daily science language routines and sentence stems aligned with ELPS and SEPs (Science and Engineering Practices from NGSS or TEKS).

3. Low Transfer Between Contexts

They ace the guided notes but fail the quiz. Why? Because they memorized, not mastered. If they can’t apply a concept to a new scenario, that’s a sign of shallow learning.

🔁 Strategy: Use “Explain It a New Way” tasks—where students have to restate concepts using visuals, analogies, or peer teaching.

4. Avoidance Behaviors in Science Settings

Students who are quiet, disengaged, or acting out during science might not be “off task”—they might be overwhelmed. When science feels inaccessible, students often hide behind behaviors.

👀 Watch for: Sudden trips to the nurse, forgotten supplies, or refusal to participate in labs.

5. Data Doesn’t Improve Despite Support

If your Tier 2 data (quizzes, small-group notes, informal checks) shows little to no growth over time, that’s a red flag. These students likely need individualized Tier 3 plans, not just more group support.

How to Confirm Tier 3 Needs With Data

Use a triangulated data approach:

• Formative Assessments (exit tickets, probes)

• Observational Notes (engagement levels, misconceptions)

• Campus Benchmarks (unit tests, universal screeners)

Align with your district’s RTI process and TEKS mastery levels. Look for patterns, not just moments.

🧭 So What Do You Do Next?

Here’s the good news: You don’t have to create a Tier 3 plan from scratch.
You just need three things:

1. A clear process for identifying who needs help

2. A strategy to target the right gaps

3. A toolkit to take action—fast

That’s exactly what we’ve put together for you.
