The screening was done. The data was in. And I was sitting at a low kindergarten table with a class roster in front of me, looking at one row that didn’t fit.
As an Academic Coach supporting K-5 teachers, part of my job was sitting with grade-level teams to make sense of our beginning-of-year screening data. This particular child had a phonemic awareness assessment score near the bottom of the class. But her reading level, her comprehension checks, her participation in book discussions all said she was doing fine. Two columns telling two different stories about the same student. Her teacher looked at the row and said what a lot of teachers say: “But she’s one of my stronger readers.”
That gap between the two stories is the whole reason a phonemic awareness assessment earns its place in your screening calendar. It isn’t there to confirm what you already see. It’s there to catch what you don’t. The screening had done its job by surfacing that mismatched row. The real question, the one this post is about, was what to do with it.
A phonemic awareness assessment is a short oral screening that measures whether a child can hear, isolate, blend, segment, and manipulate individual sounds in spoken words, with no print and no pictures involved, and it matters because that sound-level skill is the foundation decoding is built on. A low score doesn’t just flag a struggling reader. It points to a specific, teachable gap underneath the reading.
That last part is what makes the assessment worth the five minutes. Most of the measures in your data binder, like running records, retelling checklists, and comprehension questions, tell you what a child does with meaning. They’re useful. But a child with strong vocabulary and verbal reasoning can lean on meaning to pass every one of them, year after year, while a sound-level gap sits underneath, unseen.
The phonemic awareness assessment strips meaning away. No text, no illustrations, no story context to fill the gaps. It asks the question directly: can this child work with the individual sounds in spoken language? When the answer is no for a child who looks like a reader on every other measure, you’ve found something the rest of your data was never built to show you.
There are two types you’ll work with, and they answer different questions. Knowing which one you’re holding changes how you read it.
Universal screeners are criterion-referenced. They measure a child against a clear benchmark, has she mastered this skill or not, and you give them to every student several times a year, no matter how well a child appears to be doing. The IES foundational skills practice guide (Foorman et al., 2016) specifically recommends universal screening as a core practice for kindergarten through third grade. This is the tool that catches the compensators, the children whose reading performance hides the gap. The Florida Center for Reading Research and Reading Rockets both host free, teacher-facing guidance on universal screening if you’re building this into your calendar for the first time (FCRR Universal Screening K–2 guide; Reading Rockets Screening and Assessment).
Progress-monitoring assessments are the quick, repeated checks you use after you’ve identified a student who needs support. They don’t screen for the gap. They tell you whether your instruction is closing it. Flat scores week over week mean the plan needs adjusting. Rising scores mean the child is gaining ground.
The screener finds the student. Progress monitoring tells you whether you’re helping. Most teachers I work with have one and not the other, and the missing one is almost always the universal screener, because we assume the struggling readers are already obvious. The whole point of universal screening is that some of them aren’t.
Here’s where the data gets genuinely useful, and it’s the part a single score can hide.
Phonological skills develop along a continuum, from larger units of sound like syllables and rhymes down to individual phonemes. A good phonemic awareness assessment doesn’t just tell you a child is “behind.” It tells you where on that continuum her skills stop holding. Can she segment syllables but not onset-rime? Can she blend phonemes but fall apart when asked to delete one? Two children with the same low score can have completely different gaps, and need completely different instruction.
This is the difference between knowing a child struggles and knowing what to do Monday. A single number says “behind.” A continuum-based reading says she’s solid through onset-rime and breaks down at phoneme deletion, so start there. One sends you back to generic practice. The other hands you a place to begin.
The most useful assessment I found for this was the PAST, the Phonological Awareness Screening Test, included in David Kilpatrick’s Equipped for Reading Success. What the PAST gave me, back when I was a reading interventionist, wasn’t a verdict. It was a location. It showed me exactly where in the progression a student was starting to struggle, which meant I could stop guessing and start grouping. Children who broke down at the same level went together, and instruction targeted that level instead of a random point I’d picked and hoped was right. I stopped assigning more practice and started assigning the right practice, and students stuck for weeks finally moved, because instruction was aimed where the gap actually was.
If you want the fuller picture of what phonemic awareness is and why it sits at the foundation of reading development, the research is clear and it’s accessible. But the assessment is where it stops being abstract. This is where you find out which of your students have been working around a gap instead of through it, and exactly where that gap begins.
There’s a belief that a student reading on level, or close to it, doesn’t need a phonemic awareness screening, that screening is for the kids already flagged. That belief is exactly how students slip through for years. A child with strong language comprehension and vocabulary can use context, memory, and reasoning to pass every meaning-based measure you hand her. But if no one asks her to work with sounds in isolation, no one discovers the foundational layer is missing. Universal screening means screening every student, because the entire reason this assessment exists is to catch what the other measures can’t.
And if you’re thinking a phonemic awareness screening is one more thing on an already-packed calendar, I understand. But five minutes of screening gives you more useful information than an hour of running records, because it measures something they were never designed to touch. It doesn’t add to the pile. It replaces guesswork with a target.
You don’t have to overhaul your assessment system to start here. You need one thing: a phonemic awareness screener, given to every student, early in the year.
When the results come back, look for the row that doesn’t fit. Then read it past the single number. Where on the continuum do her skills stop holding? That’s where instruction begins. Not at grade level, not where you think she should be, but where the data says she actually is. Ten minutes a day of explicit practice, aimed at the right level, is the smallest and most specific change you can make for that child.
Knowing what the assessment measures and being equipped to act on every result are two different things. That gap is real, and it’s the one most of us were left with, not because we didn’t care, but because the training never covered it. You don’t have to close it all at once. Start with one screener and one mismatched row.

If that mismatched row sounds familiar, if you have students who look fine on the surface but something about their reading isn’t adding up, the five-minute screening is where you start, and reading the result well is what turns it into a plan.

Phoneme segmentation is the ability to break a spoken word apart into its separate sounds and say each one in order. It’s the encoding skill, the one a child leans on to spell, because writing a word she’s never seen means first hearing the sounds inside it and then matching each sound to a letter.
Phonemic awareness skills are the specific abilities a child uses to hear and work with individual sounds, or phonemes, in spoken words. There are four that matter most, they build on each other in order, and knowing which one a student has reached tells you where reading instruction should pick up.
Phonological awareness is the broad ability to hear and work with the sound structures of spoken language: words, syllables, rhyme, and individual sounds. Phonemic awareness is one skill within that umbrella, hearing and manipulating the individual sounds (phonemes), and it’s the hardest and last to develop. The difference matters because a child can be strong at the easy, early levels and still be missing the phoneme-level skill decoding depends on.
