NBPTS Component 3 Portfolio - How to Avoid Common Errors

Let’s talk about one of the biggest frustrations National Board candidates face:

“Why did I only get a 2 when I worked so hard on Component 3?”

Every year, after scores are released, candidates feel confused, frustrated, and unsure where things went wrong. With Component 3 counting for 30% of your total score, it’s a huge piece of your journey to certification.

In my 26 years of supporting candidates, I’ve found that aiming for a 2.75 in Component 3 gives you a strong foundation for success. Some teachers have certified with lower scores, but 2.75 is a reliable comfort number — it gives you some cushion for the other components.

Let’s dig into the most common mistakes that lead to lower scores — and what you can do instead.

1. Video Recording Problems

Your video is your evidence in Component 3. If assessors can’t see or hear key interactions, your evidence is incomplete.

Common mistakes include:

• Poor camera placement that misses student interactions
  
  
• Audio quality too low to hear discussions
  
  
• The camera focusing only on the teacher instead of showing students learning

Fix it:
Plan your recording intentionally. Whoever is filming should know the lesson plan, objectives, and when to capture teacher-student and student-student interactions. Avoid just setting up a camera and hoping for the best.

2. Technical Violations

 Stay within the rules!

• No editing. Submit a continuous recording.
  
  
• Keep it under 15 minutes. Assessors will stop watching after that mark — even if your best moment is next.

  Simplicity wins here.

3. Weak Instructional Design

Component 3 measures how your instruction impacts student learning.

Avoid lessons that:

• Only test recall instead of higher-order thinking
  
  
• Treat all students exactly the same
  
  
• Feel too “perfect” and don’t show real teaching challenges

The National Board isn’t looking for flawless teaching — they’re looking for your ability to reflect on your practice and make data-driven decisions.

4. Low Student Engagement

Students must be visibly doing the learning.

If your video shows students quietly staring at you for 15 minutes, assessors can’t see evidence of impact.

Fix it:
Include moments of:

• Discussion and questioning
  
  
• Collaboration between students
  
  
• Problem-solving or exploration

Your students should be active participants in their learning journey.

5. Weak Feedback Alignment

Feedback should connect directly to your learning goals.

If your objective is “Students will identify and apply least common multiples,” then saying “Good job!” isn’t enough.

Better feedback:

“Can you explain how you found that multiple?” or “Show me another way to find it.”

That kind of feedback shows assessors that you’re diagnosing learning in real time and adjusting your instruction accordingly.

6. Misalignment Between Objective, Assessment, and Activity

When your objectives don’t match your assessments or reflections, your evidence loses power.

Ask yourself:

• How does my instruction lead students toward my objective?
  
  
• How does my feedback measure progress toward that goal?
  
  
• What will I do next based on what I learned?

Alignment is the backbone of strong evidence.

7. Descriptive, Not Analytical, Writing

This is a big one.

Many candidates describe what happened (“Students worked in groups…”) but don’t analyze why it mattered.

Description builds the frame.
Analysis fills it with meaning.

Use your commentary to connect your decisions, strategies, and outcomes. Show what you learned about your students — and yourself — from the experience.

8. Missing Context or Weak Rationale

Every instructional choice must have a clear why behind it.

Instead of saying:

“I used small groups to increase participation.”

Try:

“I used small groups because these students benefit from peer modeling and hands-on collaboration, which supports their need for verbal processing.”

That’s analysis — and it’s what the assessors are looking for.

9. Limited Evidence of Equity and Inclusion

Equity and fairness are core NBPTS standards.

Your Component 3 video should demonstrate:

• Equitable participation (not just the same students responding)
  
  
• Inclusion of diverse perspectives and materials
  
  
• Strategies that ensure every student can access learning

Show that you value all voices — and that every student has the opportunity to contribute.

10. Weak Analysis of Student Impact

The assessors need to see how your teaching affected student learning.

Ask yourself:

• What growth do I see in my students?
  
  
• What feedback or scaffolds helped them progress?
  
  
• How will this shape my next lesson?
  
  

That kind of reflection transforms your submission from good to exceptional.

How to Strengthen Your Component 3 Submission

Here’s a quick checklist to focus your next steps:

✅ Plan before you film. Don’t capture random lessons — film intentionally.
✅ Analyze more, describe less. Focus on why things worked or didn’t.
✅ Show student learning, not just teacher performance.
✅ Align your objectives, assessments, and reflection.
✅ Use evidence to back up every claim you make.

❤️ Final Encouragement

Component 3 can feel overwhelming — but it’s also one of the most rewarding parts of the National Board process.

It’s your chance to see yourself teaching, reflect deeply, and grow stronger as an educator.

• Film with intention
  
  
• Reflect with honesty

You’ve got this, friend. 🌟
