Heart Words Assessment: How to Track Student Progress

Share or save this post!

If you’ve ever felt frustrated watching students guess at heart words during reading, spell said as “sed,” or struggle with the same irregular words week after week, you’re not alone.

For years, I assessed heart words the same way most teachers do: flash cards. A student either read the word correctly or they didn’t. If they didn’t, I’d put it back in the practice pile and move on.

But here’s what I didn’t realize: reading a heart word isn’t the same as truly knowing it.

When I started assessing heart words differently, everything changed. Not only did my students’ progress improve, but I finally had data that actually told me what to do next.

Let me walk you through what shifted for me and how you can use systematic heart word assessment to move beyond guessing and into real, targeted instruction.

The Problem with Flash Card-Only Assessment

Flash cards tell you one thing: can this student recognize and read the word in isolation right now?

But they don’t tell you:

• Can the student spell the word from memory?
• Do they understand which part of the word is irregular (the “heart part”)?
• Can they use the word accurately in writing?

I learned this the hard way when one of my students could breeze through a stack of heart word flash cards but couldn’t spell a single one of them correctly during dictation. She had memorized the visual shape of the words but hadn’t mapped the sounds to the letters.

That’s when I realized: if I’m only testing reading, I’m only getting half the picture.

The Two-Part Heart Word Assessment That Changed Everything

Now, I assess heart words two ways: reading AND encoding (spelling).

Here’s what that looks like in practice:

Part 1: Reading Assessment

I have students read a list of 10 heart words from the current unit (or you can use cumulative lists if you’re tracking long-term progress). I mark which words they read correctly and which ones they misread or hesitated on.

Part 2: Encoding Assessment

Then, I dictate the same 10 words. Students write each word on their recording sheet. This is where the real learning gaps show up.

Sometimes a student can read could perfectly but spells it “cood” or “cud.” That tells me they haven’t fully mapped the heart part (the -oul- spelling). They’re relying on visual memory for reading but don’t have the orthographic connection strong enough for spelling.

This two-part approach gives me the full picture of what each student actually knows.

What I Do With the Data (And What I Don’t)

Here’s something important: heart word data does NOT determine small group placement.

Small group reading instruction is driven by phonics skills. Heart words are practiced and assessed as part of ongoing reading and spelling work, but they don’t dictate grouping.

Instead, heart word assessment data tells me what each individual student needs to practice.

For example:

• If Mia can read they but not spell it, she needs more practice mapping that word.
• If Jordan struggles with both reading and spelling said, have, and your, those three words go on his personal practice list.
• If Ava has mastered all 10 words in reading and spelling, she’s ready to move on to the next set.

The data informs individual practice, not grouping.

How I Make Assessment Quick and Manageable

I know what you’re thinking: “This sounds great, but I don’t have time to assess every student on 10 words twice a week.”

I get it. Here’s how I make it work:

Option 1: Integrated Assessment During Small Groups

Instead of pulling students aside for a separate heart word check, I embed assessment into my small group reading time.

I have students:

1. Read 1–2 sentences that include target phonics patterns AND several heart words from the current unit.
2. Write 5 words and 1–2 sentences from dictation that mix decodable words and heart words.

This single activity serves as my phonics AND heart word assessment all in one. It takes about 5 minutes per student, and I can do it while the rest of the group is working on independent practice.

Option 2: Weekly or Bi-Weekly Heart Word Check

If you prefer a more focused assessment, you can do a quick heart word check once a week or every other week:

• Read a list of 10 words (I use the lists from my Heart Words Assessment tool)
• Write the same 10 words from dictation (you can do this whole class)

Both approaches work. The key is consistency and making sure you’re assessing both reading and spelling.

What I Send Home to Parents

One of the best things about systematic assessment is that it gives parents clear, actionable information.

After I assess, I send home:

• A letter explaining the results (which words their child has mastered and which ones still need practice)
• Flash cards for the words that need work
• A simple word mapping template so families can practice at home the right way (not just by writing the word 10 times or doing rainbow writing)

This approach has been a game-changer for parent communication. Instead of vague feedback like “work on sight words,” I can say: “Here are the 5 heart words Jordan is working on this week. Here’s how to practice them effectively.”

The Results: Students Who Actually Learn the Words

Since I started assessing heart words this way, I’ve seen two major shifts:

1. Students retain the words longer. When students map heart words instead of just memorizing them, the learning sticks. They’re building real orthographic knowledge, not just visual memory.

2. I finally know what to teach next. Before, I was guessing which words to review or which students needed extra support. Now, I have data that tells me exactly where each student is and what they need.

Assessment isn’t about testing. It’s about knowing what to do next.

Ready to Try This in Your Classroom?

If you’re ready to move beyond flash card drills and start using assessment that actually drives instruction, here’s what I recommend:

✅ Start small. Pick one small group and try a two-part assessment (reading + encoding) this week.
✅ Track the data simply. You don’t need a fancy system. A simple checklist works.
✅ Use the results to assign targeted practice. Give students only the words they need to work on, not the whole list.

And if you want a ready-to-use system that includes everything you need (reading assessments, spelling tracking sheets, parent letters, and progress reports), grab my Heart Words Assessment & Progress Monitoring tool and Heart Words Parent Letter & Homework Practice Guide These are aligned to UFLI lessons, fully editable, and designed to make this process as simple as possible.

You’ve got this. Let’s stop guessing and start using assessment that actually helps our students learn.
