What Does "Below Grade Level" Really Mean? A Parent's Guide to School Data and Intervention
Written by: Jessie Miller, Founder of PHB
There are a lot of words and phrases educators use every day that can be confusing to parents. Teachers spend so much time talking about assessments, benchmarks, percentiles, intervention groups, and progress monitoring that it is easy to forget this language is not common knowledge outside of school.
I will admit that when I was teaching, I was sometimes guilty of this too.
One phrase you may see on a progress report or hear during a parent teacher conference is:
“Your child is performing below grade level.”
Those words can feel heavy. If I heard them as a parent without any additional explanation, my mind might immediately jump to the worst case scenario:
Is my child failing? Are they going to be held back? Does this mean they have a learning disability? How did I not know?
Take a breath. “Below grade level” does not automatically mean any of those things.
It is information, not a prediction of your child’s future.
What does “below grade level” mean?
In general, “below grade level” means that your child is not yet consistently demonstrating one or more of the skills their school expects students to have at that point in the school year.
The word yet matters here.
The phrase may be based on:
A benchmark or universal screening assessment
A diagnostic assessment
Classroom assignments
Curriculum based measurements
Teacher observations
State academic standards
A combination of several sources of information
Many schools give benchmark or screening assessments at the beginning, middle, and end of the school year. These assessments help educators identify which students are meeting expectations, which students may need additional instruction, and which specific skills should be targeted.
Depending on the school and assessment, your child’s performance may be compared with:
Grade level standards
Students in the same grade nationally
Students in the same grade within the state
A locally established benchmark
Your child’s own previous performance
This is why the most important question is not simply, “Is my child below grade level?”
It is:
“Below grade level according to which measure, and in which specific skill?”
In this article, you'll find,
“Below grade level” is not one universal category
This is an important correction because the phrase does not have one nationally standardized definition.
A score below the 50th percentile does not automatically mean a child is below grade level. The 50th percentile simply represents the middle of the assessment’s comparison group. A student can score below the 50th percentile and still meet grade level expectations.
A school may use terms such as:
On track
Approaching expectations
Below benchmark
At risk
Some risk
Significantly below benchmark
Below grade level
Well below grade level
These terms are defined by the assessment publisher, school, or district. Always ask what the category means within your child’s specific assessment system.
What can the data look like?
Academic performance is often more specific than one overall reading or math score.
For example, a math diagnostic may show:
Operations and algebraic thinking: on grade level
Numbers and operations in base ten: above grade level
Measurement and data: below grade level
Geometry: on grade level
This does not necessarily mean the child is “bad at math.” It means one area may need more attention.
Reading data may be broken into skills such as:
Phonemic awareness
Phonics
Vocabulary
Oral reading fluency
Reading accuracy
Reading comprehension
A child could read quickly and accurately but struggle to explain what the text means. Another child might understand a story when it is read aloud but have difficulty decoding the words independently. Both children may receive a “below grade level” reading score, but they need very different support.
That is why an overall score should be the beginning of the conversation, not the end of it.
What does a percentile mean?
Percentiles can be confusing, especially because they sound like percentages. But a percentile rank is not the same thing as the percentage your child earned on a test.
A percentile tells you how your child’s score compares with the scores of other students, usually same-aged or same-grade peers who took the same assessment. These students are called the comparison group or norm group.
Imagine 100 same-aged students standing in a line, ordered from the lowest score to the highest score.
If your child scored in the 40th percentile, their score was the same as or higher than the scores of about 40 students in that group. About 60 students scored higher.
Here are a few more examples:
15th percentile: Your child scored the same as or higher than about 15 out of 100 same-aged peers. About 85 scored higher.
40th percentile: Your child scored the same as or higher than about 40 out of 100 same-aged peers. About 60 scored higher.
50th percentile: Your child scored near the middle of the comparison group. About half of their same-aged peers scored lower, and about half scored higher.
75th percentile: Your child scored the same as or higher than about 75 out of 100 same-aged peers. About 25 scored higher.
90th percentile: Your child scored the same as or higher than about 90 out of 100 same-aged peers. About 10 scored higher.
Here is where parents often get tripped up: If your child is in the 40th percentile, it does not mean they answered only 40 percent of the questions correctly. They may have answered far more than 40 percent correctly. The percentile only tells you how their score compared with the scores of other students in the assessment’s comparison group.
It is also important to ask who is included in that comparison group. Depending on the assessment, your child’s score may be compared with same-aged or same-grade peers nationally, statewide, or within the school district.
A percentile also does not automatically tell you whether your child is on or below grade level. For example, a child at the 40th percentile may still meet the assessment’s grade-level benchmark. The school must compare the child’s actual score with the specific benchmark or cut score used by that assessment.
That is why it is helpful to ask:
“Is this a percentile rank or the percentage of questions my child answered correctly?”
“Is my child being compared with same-aged or same-grade peers?”
“Is the comparison group national, statewide, or local?”
“Does this percentile meet the grade-level benchmark on this assessment?”
“What specific skill does the score suggest my child needs to work on?”
The percentile gives you one helpful piece of information, but it should be considered alongside classroom work, teacher observations, other assessments, and your child’s growth over time.
One score is a snapshot, not the whole photo album
A benchmark score shows how your child performed on a particular assessment, on a particular day, under a particular set of circumstances.
Maybe your child was tired. Maybe the testing format was unfamiliar. Maybe they rushed. Maybe they were distracted by the class pencil sharpener that apparently needed to be used 47 times that morning.
Those factors do not mean the results should be ignored. They mean the score should be considered alongside:
Classroom work
Teacher observations
Previous assessment results
Progress throughout the year
Performance on other measures
Your child’s attendance and access to instruction
Language development
Testing accommodations
Social, emotional, or health factors that may have affected performance
A pattern across multiple data points tells us much more than one isolated score.
Does “below grade level” mean my child will be retained?
No. A below grade level score by itself does not automatically mean your child will repeat a grade.
Retention policies vary by state, district, school, and grade level. Schools typically consider several factors rather than relying on one benchmark score. Those factors may include classroom performance, state assessments, attendance, growth, teacher recommendations, and local or state retention requirements.
If retention is a concern, the school should discuss it directly with you. You do not need to treat every “below benchmark” report as a secret code for “your child is being held back.”
What happens after a child scores below grade level?
Depending on the results and the school’s procedures, the teacher may:
Reteach the skill during regular classroom instruction
Provide additional small group instruction
Monitor the child more frequently
Collect more diagnostic information
Place the child in a targeted intervention group
Consult with an instructional specialist or school support team
Adjust the intervention based on the child’s response
Many schools organize this support through a Multi-Tiered System of Supports, commonly called MTSS, or through a Response to Intervention framework, commonly called RTI.
The exact names and structures vary, but the general idea is that students receive increasingly targeted support based on their needs and their response to instruction.
A common framework looks something like this:
Tier 1: High quality instruction provided to all students in the general classroom
Tier 2: Additional targeted instruction, often delivered in a small group
Tier 3: More intensive, individualized instruction with closer progress monitoring
Not every school uses these exact labels, group sizes, schedules, or criteria.
What is an intervention group?
An academic intervention group is a targeted instructional group focused on a specific skill.
During an intervention period, a grade level might have several groups working at the same time. One group may practice reading fluency, another may work on phonics, and another may focus on multiplication fact fluency.
Effective intervention should be more than simply repeating the exact same lesson in the exact same way and hoping it magically lands this time. It should provide explicit, targeted instruction based on the student’s identified needs.
Research supports the value of targeted academic intervention. A meta-analysis of 33 rigorous studies found that reading interventions produced meaningful positive effects for students in Grades 1 through 3 who were at risk for reading difficulties (Gersten et al., 2020). Research has also found positive effects from foundational-skills and multicomponent reading interventions for students who experience reading difficulties (Denton et al., 2022).
In other words, intervention is not a punishment or a label. It is additional instructional time intended to prevent a manageable gap from becoming a much larger one.
How will the school know whether the intervention is working?
This is where progress monitoring comes in.
Progress monitoring involves using short, repeated assessments to measure whether a student is making enough progress toward a specific goal. Instead of waiting until the end of the grading period to discover that something is not working, educators can review the data and make adjustments along the way.
Research on curriculum based measurement has found that progress monitoring can support stronger instructional decision making, particularly when teachers use the results to adjust instruction rather than merely collect more scores (Stecker et al., 2005).
The data should help the school answer questions such as:
Is the child improving?
Is the child improving quickly enough to reach the goal?
Is the intervention being delivered consistently?
Does the intervention need to continue?
Does it need to be changed or intensified?
Is more diagnostic information needed?
There is no single national rule requiring a certain percentile, number of data points, or length of time before a child enters or exits an intervention group. Those decisions vary by program, district, assessment, and student need.
Some students receive intervention briefly and return to their regular instructional group. Others need support for a longer period. Children can move into, between, and out of intervention groups as their needs change.
Does receiving intervention mean my child has a learning disability?
No. Receiving an intervention does not automatically mean a child has a disability or needs special education.
General education interventions are commonly provided before, during, or separately from a special education evaluation. They give the school an opportunity to address an academic need and observe how the child responds to targeted instruction.
However, intervention should not be used to indefinitely delay an evaluation when a disability is suspected. Parents may ask the school in writing about a special education evaluation at any time. The evaluation and eligibility process is governed by federal and state requirements, so the exact procedures and timelines should be explained by your child’s school or district.
If your child continues to struggle despite appropriately targeted, consistently delivered intervention, it is reasonable to ask what additional evaluation or support should be considered.
What if you only receive a letter about intervention?
Sometimes, parents receive a letter containing benchmark results and a brief notice that their child will begin receiving intervention. The letter may include the name of the assessment, a few scores, and an intervention label, but not much explanation about what any of it actually means.
If this happens, you have not missed anything. The school may use a standard notification letter, but that letter does not always provide the full picture.
Consider emailing your child’s teacher or scheduling a short in-person, phone, or Zoom meeting. You can use that conversation to learn:
Which specific skill needs support
What your child’s score means
What intervention they will receive
How often the intervention will take place
How their progress will be measured
When the school will review the plan
What you can realistically reinforce at home
You are not being difficult by asking for more information. You are making sure you understand the concern and the plan so you can be an informed member of your child’s support team.

Questions to ask when your child is below grade level
You do not have to become an assessment expert overnight. You simply need enough information to understand the concern, the plan, and how progress will be measured.
Start with these questions:
Which specific skill is below grade level?
Ask for something more precise than “reading” or “math.”
What assessment was used?
Find out whether it was a screener, benchmark, diagnostic assessment, classroom assessment, or state test.
What does this score or category mean on this particular assessment?
Ask the teacher to explain any percentile, scaled score, grade equivalent, or benchmark category in plain language.
Is this concern showing up in classroom work too?
This helps you understand whether the result is part of a consistent pattern or an isolated score.
What can my child already do independently?
Data conversations should include strengths, not only deficits.
What is the intervention goal?
The goal should name the skill your child is working to improve.
What instruction will my child receive?
Ask about the program or teaching approach, group size, frequency, and length of each session.
Who will provide the intervention?
This could be the classroom teacher, interventionist, reading specialist, special education teacher, or another trained staff member.
How will progress be measured, and how often?
Ask which tool will be used and when the team will review the results.
How will I receive progress updates?
Parent communication practices vary, so clarify how and when information will be shared.
What will happen if my child is not making enough progress?
Ask how the instruction will be changed, intensified, or reconsidered.
What criteria will the school use to reduce or end the intervention?
There may be a benchmark, growth target, classroom performance requirement, or combination of measures.
Are attendance, language, vision, hearing, attention, or other factors affecting the data?
This is not about making excuses. It is about looking at the whole child.
At what point would the team consider additional evaluation?
This is especially important if the difficulty is persistent, significant, or appearing across multiple settings.
What parents can do at home
When parents hear that their child has a gap, the natural instinct is often to go into full emergency tutor mode. Before you print 63 worksheets and cancel everyone’s weekend, pause.
More work is not always better work.
1. Identify the exact skill
Ask the teacher what your child needs to practice. “Work on reading” is much too broad. “Practice accurately reading words with vowel teams” gives you something useful and manageable.
2. Ask the school to demonstrate the strategy
Teaching methods have changed, and your child may be learning a strategy that looks unfamiliar. Ask the teacher for an example, video, handout, or explanation so the language used at home matches what your child hears at school.
3. Keep practice short and consistent
A focused 5 to 10 minutes several times a week is often more productive than one exhausting hour that ends with everyone questioning their life choices.
Stop before frustration takes over. Home practice should reinforce learning, not turn your relationship into an evening intervention block.
4. Practice the skill in everyday life
Depending on the goal, you might:
Read together and talk about the meaning of the text
Practice letter sounds or word patterns
Play quick math fact games
Estimate totals while shopping
Measure ingredients while cooking
Ask your child to explain how they solved a problem
Review a small number of previously taught skills
5. Track observations, not just scores
Notice patterns such as:
Which tasks are easy or difficult
Whether your child can explain the skill verbally
How long the task takes
Which strategies help
When frustration begins
Whether the difficulty appears only during homework or in other situations too
Share helpful patterns with the teacher. You are not responsible for running the school’s intervention program at your kitchen table, but your observations can add valuable context.
6. Protect your child’s confidence
Talk about the skill as something your child is still learning, not as evidence that they are “behind,” “bad at math,” or “not a reader.”
You might say:
“This score shows us what your teachers can help you learn next.”
“You already know many parts of this. We are working on the part that is not automatic yet.”
“Needing extra instruction does not mean you are not smart.”
“Let’s notice what feels easier than it did last month.”
Your child should know that the intervention is a support they are receiving, not an identity they have been assigned.
Data should lead to action
As a former teacher, I both love data and recognize that schools sometimes collect more data than anyone knows what to do with.
Data itself is not the goal.
The purpose of assessment is to help educators and families answer three questions:
Where is the child now?
Where are they trying to go?
Is the current instruction helping them get there?
Research on data based decision making suggests that collecting scores alone does not guarantee better outcomes. The benefit comes when educators interpret the information accurately and use it to adjust instruction (Peters et al., 2021). For students with persistent needs, data based individualization uses ongoing assessment information to intensify and adapt intervention over time (Danielson & Rosenquist, 2014).
So if your child is described as “below grade level,” do not panic, and do not ignore it.
Get curious.
Ask which skill needs support, how the school is addressing it, how progress will be measured, and when the plan will be reviewed. Then find one realistic way to reinforce that same skill at home without turning every evening into a second school day.
Below grade level is a description of current performance. It is not a description of your child’s intelligence, potential, or future.
It is simply a starting point. And once everyone understands the starting point, the school and family can work together toward the same destination.
