What a School Math Screening Checks
A 2009 federal practice guide recommends that schools "screen all students" in math (Institute of Education Sciences, 2009). The guide says checks in the early grades typically cover counting and naming written numbers. In our view, a screening result is not a diagnosis. If no skill has gone, start with the teacher.
TL;DR
- A 2009 federal practice guide recommends that schools "screen all students" in math (Institute of Education Sciences, 2009). It says the aim is to find children at risk of math trouble. It says those children should then get help.
- One source is a 2009 federal practice guide (Institute of Education Sciences, 2009). It says checks in the early grades typically cover counting and naming written numbers. They typically also cover which of two numbers is bigger. The guide rated its evidence for screening as moderate.
- In our view, a teacher's concern about math is worth taking seriously. We hold no study of the classroom signs teachers use to flag math trouble.
- In our view, a screening result is not a diagnosis. Keep teaching the math while you work out what is hard. If no skill has gone, start with the teacher. Our position is that a lost skill goes to a doctor first, not a tutor.
What a school math screening is

The 2009 guide is about checks the school gives. It is not about what a teacher notices in class.
What the checks look at
The guide says checks in the early grades typically cover counting and naming written numbers. They typically also cover which of two numbers is bigger. Some checks also include simple word problems.
Of the one-skill checks, comparing numbers and counting predicted later math best. Broader checks seemed to predict slightly better.
The guide rated its evidence for screening as moderate. That rating rested on studies of how well checks predicted math a year later.
For upper elementary grades, the guide called research on math screening "underdeveloped."
A 2021 update of the 2009 guide left screening out.
What we hold on teachers noticing math trouble
In our view, a teacher's concern about math is worth taking seriously. We hold no study of the classroom signs teachers use to flag math trouble.
One review pooled 75 studies of teachers' judgments (Südkamp and colleagues, 2012). It compared teachers' judgments with the students' scores on achievement tests. The two matched fairly well, but not perfectly. The studies covered all school subjects, not math alone. They were about how students were doing, not about spotting trouble. We could read only the review's summary.
After a screening
In our view, a screening result is not a diagnosis. Keep teaching the math while you work out what is hard.
In our view, these are fair questions for the school.
- Does the school check every child's math?
- What does the check look at?
- What happens after a low result?

When to ask for help
Each of these is a reason to ask for help on its own.
- Little change, even with steady practice and good teaching.
- Math well below your child's other schoolwork.
- A teacher who raises a concern about math.
- Extreme upset about math.
- Complete avoidance of math.
- Worry about math that spreads into the rest of learning.
- Sadness or worry that lasts.
- A skill that was there and has gone. Our position is that a lost skill goes to a doctor first, not a tutor.
If no skill has gone, start with the teacher. Say what you are seeing at home, and what you have tried. Beyond the teacher, the right person depends on what it turns out to be about. If the work is too hard, someone who works on that school skill. If worry or mood is the thing, someone who works with children's mental health. In our view, if you are worried enough to ask, a professional evaluation is worth asking about.
Any talk of hurting themselves is a same-day call to your doctor or a crisis line.
In the classroom
If a math check flags a student, tell the family what it looked at.
Two sentences for an email home: "Our math check looked at counting and comparing numbers. Can we talk about what we saw?"
Tonight, write down what the school has told you about math checks. Add one question you still have. This is a record, not a test.
”What to do tonightWhat to use next
A set of questions you answer about what you see at home. A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing, or medical cause, pursue a professional evaluation too — that's the only route to those supports.

What if I am still worried after a screening?
If no skill has gone, start with the teacher. Say what you are seeing at home, and what you have tried. In our view, if you are worried enough to ask, a professional evaluation is worth asking about. As of September 2026, a US parent can ask the school for an evaluation. Put it in writing. Rules can vary by state and change. Check your state's parent-rights notice.
