How to Determine Reading Level of a Book
Leveling the field
If you have a child in school, then you’ve probably heard the term “reading level.” Your child’s teacher may have mentioned it when discussing the importance of reading practice. It may have come up during a parent-teacher conference. But, what does “reading level” actually mean? Why does it matter? And, how can you easily determine reading level of a book that is a good match for his level of reading skill?
What is reading level?
Reading level is simply a way to identify how complex a book a child can read independently. You might be tempted to reason that if your child is in the second grade, then books that are labeled for second graders will be the perfect fit for him. That’s not necessarily true. In most classrooms today, students read at a wide range of different levels. Most schools administer reading assessments periodically to determine the reading comprehension level of each child.
Why does reading level matter?
Reading level matters for a few very simple reasons. If your child is reading a book that is too far above his current ability, then he will likely become frustrated and discouraged. On the other hand, if a book is too far below his reading level, it won’t challenge him enough. He won’t encounter new words or more complex sentences, and his reading skills simply won’t grow. A book that is too far below your child’s reading level might also simply be boring. The ideas and words won’t be complex enough to catch his interest or fire his imagination.
How is reading level measured?
A search of the Internet quickly reveals a dizzying array of reading-level systems with obscuring names like ATOS, Basal Equivalent and Fry Readability Graph. It’s enough to make your head spi!. Let’s take a look at some of the most commonly used readability systems.
- Fountas-Pinnell Guided Reading Level – Sometimes referred to as Fountas and Pinnell, or even simply as Guided Reading Level, this reading-level system supports the guided reading program designed by Irene Fountas and Gay Su Pinnell. The level of individual books are classified by assessing a number of factors, including word repetitions, sentence length and complexity, and even the number of illustrations.
- DRA – DRA refers to a standardized reading test called the Developmental Reading Assessment. This reading system assigns books different reading levels that correspond with the different scores that children can earn on the test. After taking the test, a child is assigned a letter/number score from A1 through 80. His teacher – or parents – can then find books with the same DRA score.
- Lexile Framework for Reading – Called the Lexile measure or the Lexile level, this scoring system was developed by an educational research team funded by the National Institute of Child Health and Human Development. Using test scores from a standardized reading test or from the Scholastic Reading Inventory test (SRI), this system converts those test scores into equivalent reading levels making it possible to match students with the reading material best suited for their growing abilities.
- Grade Level Equivalent – Perhaps the easiest of the reading leveling systems to understand, Grade Level Equivalent measures a student’s reading level by comparing it to the expected reading level for each school year. Fourth graders in their first month of the school year whose reading skills are at that grade level would be given a reading level score of 4.1. This stands for fourth grade, first month of school. A struggling reader in the fourth grade would have a lower score, 3.6, for example. This would mean that this child was reading at a level usually expected of a third grader in the sixth month of the school year.
How can I determine my child’s reading level?
Measuring a child’s reading level is complex. Different systems measure different factors, including text complexity, word speed and even comprehension. Your child’s school will assess his reading level, most likely using a variety of methods and maybe even some good, old-fashioned teacher intuition. If you want to know your child’s reading level, your best bet is to simply ask his teacher.
How can I determine the reading level of a book?
Trying to find books that match your child’s reading level? Once again, the first step is to talk to his teacher. She will be able to offer many suggestions and may even have a reading list available. Another good resource is the school librarian. Books in the school library will already be sorted by reading level. The librarian should be able to point you to the right section.
Need more resources? Consider these:
- Renaissance ATOS analyzer – This text wizard allows you to input text – or even upload a file – to see how it rates on the Advantage TASA Open Standard readability formula. You can input a sentence, an excerpt or an entire book. Renaissance also has a book finder where you can check to see if the level of the book you’re curious about is already on file. The book finder lets you search for both the ATOS score and the Lexile measure using a book’s title or author.
- Scholastic’s Book Wizard – Scholastic.com offers a Book Wizard that allows you to search through over 65,000 children’s books. Using a book’s title or author you can search using one of four different reading level systems. You can also filter results by genre, subject and grade level.
- Lexile look up – The Lexile Framework for Reading website lets you look up books that match your child’s reading level. You can also look up the reading level of an individual book on the same page, using the book’s ISBN number or its title. Hint: the “Quick Book Search” tab is at the top right of the page.
- Correlation chart – If you already know the reading level of a book under one of the leveling systems, but need to know what the same book would rate under another system, then use this correlation chart offered by the State of Washington’s public library system. Simply move down the column under the system that you already know until you find the right rating, then move across the page – left or right – to the correlating number in the column of the system you’re hoping to target.
Learning your child’s reading level and then finding books that match is a great idea! You’ll be able to keep him engaged and learning without overwhelming him with text that is too complex or with words that are simply beyond his ability.

Tips on How To Determine Reading Level Of A Book
So how can you determine the reading level of a book? Before delving into the tools available to help you find a book that your child can read, first, you must understand what reading level is.
What is Reading Level?
The reading level of a book determines how well a child can read it independently. Unfortunately, reading level is often confused with grade level, so a book with a fourth-grade reading level is designed with vocabulary and syntax that the average fourth grader can understand.
However, it is not always as simple as picking a book that is leveled at your child’s grade level. Your child’s teacher can tell you that students fit into a wide range of levels, even within the same classroom.
As your child’s reading skills develop, you’re going to need to find reading materials that match. Knowing how to read reading levels will help.
Why Reading Level is Important
Children who are learning to read need to have a text they can read successfully. If text is too easy, the child gets bored. If the text is too hard, the child gets frustrated.
This balance is where the reading level helps. Finding a book that matches your child’s abilities and interests will encourage successful reading, and reading level is key to that.
Reading Level and Interest Level
Adding interest level to your decision-making will help guide you to the books they will be most interested in readingAnother benchmark you can check into is interest level. This metric shows how interesting a particular book is likely to be to your child based on their age or grade level.
If a child is particularly behind or advanced in reading level, finding books they want to read but match their reading level becomes more challenging. Adding interest level to your decision-making will help guide you to the books they will be most interested in reading.
Common Measures for Reading Levels
Many tools measure reading levels. As you learn how to determine the reading level of a book, you will find that these tools make the job a lot easier, so you can find a book that fits the child’s reading level. Here are some popular reading systems to consider.
1. Fountas-Pinnell Guided Reading Level
Fountas and Pinnell created the Guided Reading Level. This leveled reading system assigns a level to individual books. Factors that impact that level include repetition of words, the complexity of sentences, and sentence length.
This program uses specialized reading lists with books that already have a grade level measure.
2. Grade Level Equivalent
The Grade Level Equivalent leveled reading system assigns an actual grade level to the book based on what students typically can read at a particular stage of their education. This metric is labeled with a decimal point, where the first number is the grade level, and the number after the decimal point indicates the number of months into the school year the student would be. So, a score of 2.1 means second grade one month into the school year.
For parents that are new to reading levels, this can be a helpful metric as it shows a level they can easily relate to their student’s age and grade. However, parents need to realize that students develop their reading abilities at different speeds, so any particular child may read at, above, or below the published reading level.
3. Developmental Reading Assessment
The Developmental Reading Assessment, or DRA, assesses a child’s reading ability through a reading test. It then gives the student a score based on that test. Factors it checks include:
- Phonemic awareness
- Alphabetic principles/phonics
- Fluency
- Vocabulary
- Comprehension
- Reading engagement
Books are given corresponding scores based on text complexity and vocabulary. Thus, teachers and parents can easily connect students to books that fit their abilities after taking the test by lining up the test scores with the scores of the book.
4. Lexile Framework for Reading
The Lexile Framework is a National Institute of Child Health and Human Development metric. It uses Scholastic Inventory Test scores to evaluate text and determine what reading level it is.
To use the Lexile Framework, students must take a standard test or the Scholastic Reading Inventory (SRI). This then matches them with a reading level that matches their ability.
You can look up the Lexile level of a book online on the Lexile website.
5. Accelerated Reader Book Levels
Accelerated Reader is a complex readability formula that rates text complexity. It uses grade level ratings to indicate what year and month a student could read a book independently.
Accelerated Reader is different from straight grade level equivalents because it uses interest level as well. This indicates if the content of a book is age-appropriate for the particular grade level.
Tools to Find the Reading Level of a Book
Understanding the different reading tests and reading level measures is important, but it does not help you learn how to determine the reading level of a book when your child wants to read something. Thankfully, you have several tools at your disposal to help.
1. Scholastic’s Book Wizard
Scholastic offers a book wizard tool that has over 65,000 children’s books in the database. You can search using the title and author to find an individual book’s reading level. If you are looking for recommendations for your child, you can search by reading level, subject, grade level, or genre and get a list of suggestions.
2.
Renaissance ATOS AnalyzerIf you can’t find your book or text in another tool, you can copy a portion of the text into the ATOS Analyzer to see how it rates. This tool uses a readability formula to tell you how easy something is to read. It also merges with the Lexile measure, so you can search for individual books if they are in the database.
3. Lexile Look Up
Lexile’s online tool lets you search for a book by its ISBN. Just enter the number on the Quick Book Search to see if it is in the database. The website also allows you to look at a list of books based on your child’s reading level.
4. Accelerated Reader Search Tool
The AR search tool lets you search for a particular book’s readability, Lexile level, and interest level. It reports a grade level based on whether or not a child will be challenged in the reading but not frustrated.
5. Correlation Chart
The Correlation Chart is part of the State of Washington public library system. It lets you find the reading level of a book, then use the tool to compare that to the reading level in another measurement. If you are looking for a specific measure but know another one, this tool can help you compare.
A Final Word on How to Determine Reading Level of a Book
Reading levels help you choose books for your child that fit their interests and abilities. You can avoid frustration and boredom by selecting appropriate books. Using reading levels also encourages more independent reading, especially with young readers.
Parents can sometimes struggle with finding reading levels for different books, but using a book’s ISBN, you can search in several tools that have book lists based on reading level. Using these tools and asking your child’s teacher what their current reading level is will allow you to choose the right reading material for your child.
FAQs About how to Determine Reading Level of a Book

4. What reading speed is considered normal for adults and children?
5. How to choose the right text to test reading speed?
6. The book "Everything you wanted to know about speed reading, but were afraid to ask"
How to check reading speed?
The easiest way is to take a stopwatch (you can use the application on your phone), a text to check your reading speed and read it at a normal pace for one minute. It is important that the text is non-technical, does not contain highly specialized terms and concepts, and is not familiar to the reader. The text should not be too primitive. The testee must see the text for the first time so that the results are not artificially inflated.
But what do you care about speed, if you don't understand with what awareness you absorb the text? :)
A much better way to find out your reading speed is to take a free online test. To do this, sit back, enter your name in the form above, press the button and you will immediately see the text that you need to read, slowly, trying to understand everything that is written.
When the entire text is read - click on the button at the very bottom. The program will automatically determine the reading speed and prompt you to answer a few questions to understand the degree of assimilation of the material. As a result of testing, you will receive not only the result of your reading speed and awareness, but also recommendations for improving your reading technique in the format of the book "Everything you wanted to know about speed reading, but were afraid to ask." Enter a name. Click the button and find out your real reading speed. Have a good day.
How can I test my reading speed myself?
We have prepared for you a tool with which you can independently check the speed of reading. Our tool include a certain amount of text that you need to read as quickly as possible. You will then have the opportunity to answer a series of questions about the text, allowing the program to determine your level of understanding. Based on the data received, a result and a certificate are issued. This certificate can be shared with your friends on social networks and challenge them to a battle to test the speed and awareness of reading :).
If you want to do it yourself, you can do it according to the following scenario. A text of medium complexity is taken, located on one sheet. You will need an assistant who will keep track of the time and will be able to test the level of your understanding of the information. Check algorithm:
Simultaneously with the start command and the start of the stopwatch, you begin to silently read the text.
When the text is finished, you say stop - time stops.
Then you need to answer a few questions regarding the content (reading speed implies a full reading comprehension).
The last step is to count the words in the text and determine the average number of words per minute (words in the text can be counted before reading).
This is the certificate you can get based on the results of passing the test
How to check the reading speed of a child?
A child's reading speed can be tested in a similar way. The child should read aloud, at least in elementary school. Then you can switch to the usual way of checking for adults.
Schools often test reading skills by counting the number of words read per minute. This gives a small error, since words come in different sizes, but a similar verification method can also be used.
What reading speed is considered normal for adults and children?
The average reading speed for an adult is 200-230 words per minute. Below average, but an acceptable rate is 150-200 words per minute. Adults who read more than 230 words per minute are considered fast readers. For the speed reading technique, the optimal speed is 350-400 words per minute.
In children, the indicators are dynamic and change depending on age. Approximate norms used in elementary school:
20-30 words per minute for first grade;
45-60 words per minute for second grade;
70-85 words per minute for third grade;
90-125 words per minute for fourth grade.
How to choose the right text to test reading speed?
The criteria for selecting text to test reading speed are identical for adults and children. The only difference is the volume and complexity of the information. The text must match the following parameters:
medium difficulty appropriate for age;
the absence of specific unfamiliar words or their minimum number;
no dialogs;
location on one page;
large, comfortable to read font;
lack of pictures and other distracting elements.
In our tool for testing reading speed and comprehension, we tried to take into account all these factors so that the resulting tool would be convenient for both adults and children. At the same time, he gave a fairly clear answer to the question about the real reading speed.
It should be remembered that reading speed is a variable parameter, which decreases if a person rarely sits down at a book, and increases with constant reading. There are many special techniques aimed at significantly increasing the speed of reading text information.
Everything you wanted to know about speed reading but were afraid to ask test. So don't waste a second,

We have already written so much here about how to correctly measure your reading speed, achieve awareness and interpret the results, that every second of delay before you pass the online reading speed test and receive a personal certificate is just like death. Return to the very beginning of the page, enter your name in the field under the video and go to the enchanting world of unfamiliar texts and tricky questions :).
📖 Reading speed Q&A section
📕 What formula is used to calculate reading speed?
If it’s very short, then the formula for calculating the reading speed is as follows: V = (Q / T) x K. This formula allows you to get a real figure for reading speed with a correlation to the coefficient of meaningfulness. You can read more about the formula here in this article .
📗 What books do you recommend reading to develop speed reading?
We have compiled a list of the most useful books for the development of speed reading and posted it in a separate post on the blog. The list is constantly updated and gives an idea of the main books with which you can develop speed reading skills.
📘 What if I want to increase my reading speed?
You can start by learning the theory, or you can download our workbooks , which we have created especially for those who who wants to start learning speed reading.

Measuring Reading Speed
Chapter 1 No Models
Genes and Memes
Whoever you are, your brain can change. Everything depends on you. It doesn’t matter what opinion you yourself or others about your creative abilities have: abilities can be developed. The task of revealing creative potential has been facing people for a long time. But if earlier creative gurus relied on their experience and intuition in their training, today the latest technologies have come to the rescue. The brain can learn and change until death. This ability is called neuroplasticity. No matter what you have experienced and what genes you have inherited, consciousness, that is, the way you think, can change the structure and anatomy of the brain. When you opened this book, your brain had a certain structure, certain neural connections. At the end of reading, other connections will appear, and this structure will change. Without a doubt, the brain will become better, because you will learn about its capabilities and limitations. If, in addition, you regularly apply the described techniques, your creativity will increase. Changes will be noticed not only by you, but also by colleagues, relatives and friends: I know this from myself (I am my main guinea pig) and from hundreds of people with whom I was lucky to work. I want to share this knowledge with you, dear readers, to help you become a more creative and live a rich and happy life.
How did mankind come to its present position? We survived, in part, thanks to two continuous processes: biological evolution and cultural development. Evolution consists in the accumulation of such genetic mutations that make their carriers better adapted to their environment. This accumulation occurs as a result of natural selection, unconscious and uncontrollable. In culture, on the contrary, the main role is played by the creative forces of mankind, which radically change the cultural paradigm. And this is a completely conscious process.
It is possible to draw a parallel between creativity and gene mutations in the course of evolution
The nervous system is arranged in such a way that the discovery of something new, so important in creativity, stimulates pleasure centers. However, the passion for learning and research depends not only on genetics, but also on childhood experience. If this is true, then our ancestors recognized the importance of inventions, protected innovators and learned from them: the survival of society in the face of unforeseen circumstances and threats depended on the creative abilities of such people.
In addition, another much more primitive and effective force, peace, played an important role in our survival. For the most part, energy is stored when there is no active action, when the body and mind are at rest. The need to conserve energy is so strong that we associate free time with relaxation. Take a walk in the park, watch a movie, read a book, or just stare at the ceiling. Turn on autopilot. Don't waste energy. Thus, we humans strive to fulfill two mutually exclusive orders of the brain: on the one hand, to make as little effort as possible (peace), and on the other hand, to seek and explore new things (creativity).
For most of us, it seems that peace is stronger than the pleasure of new challenges and ideas. Fortunately, some are much more willing to succumb to the joy of discovery. But, even if it's not you, creativity will bring incredible pleasure no matter where and when you find a use for it. When we create, we feel great.
To recap. We are born with two conflicting commands. On the one hand, we are programmed to conserve energy - this manifests the instinct of self-preservation. On the other hand, we tend to strive to push boundaries, to explore, to enjoy discoveries, even to be in danger. So, curiosity is inherent in all children. The second impulse leads to creativity. We need both "programs", but the first does not require much effort, maintenance and motivation. Creativity is difficult to develop on your own. In adult life, at work and at home, there are not so many opportunities for curiosity and new discoveries, but there are many obstacles that prevent you from taking risks and exploring. Therefore, the motivation needed to be more creative quickly fades, and as a result, most do not consider or feel that they are creative individuals.
While genes are passed down automatically from generation to generation, things are different with inventions and ideas. Every child should learn from the very beginning how to use fire, the wheel, or atomic energy. The pieces of information that have to be learned in order for a culture to continue are called “memes,” a term from Richard Dawkins’ The Selfish Gene*. All memes - from language and numbers to theories, songs and laws - must be passed on to children or will be lost. Therefore, memes can be considered the cultural equivalents of genes.
An extremely creative person can change a meme. And if society accepts this, then the meme will enter the culture. New songs, ideas, technologies - that's what creativity is. However, memes do not appear spontaneously, as in biological evolution with mutated genes. To change the tradition, you need to make an effort, as well as educate future generations. Everything new requires attention, and this is a very limited resource. We are not able to process too much data at once, and constant employment makes it difficult to come up with something out of the ordinary. Most of the time is spent on daily activities at work and at home.
In other words, to become more inventive in any area, you need to "free up" the lion's share of attention.
If we are busy all the time, we are unlikely to come up with ideas that can change or improve a product, a song, or a way of life idea or action. This is the destruction of habitual, well-established patterns of thinking, which happens to everyone, with some more often, with others less often. The novelty and value of ideas aimed at changing paradigms and memes within a particular tradition, culture or science are determined by experts in this field or discipline. Thus, the innovation receives a social assessment: "This is really unusual." Creativity is not limited to thoughts in the head, it manifests itself through the interaction of ideas with the socio-cultural context. It's more of a social phenomenon than a personal one.There are other definitions of creativity. A creative person is an interested and inspired person with non-standard thinking; a person with an original view of the world; a versatile person without prejudice, who, through insight, is able to invent products and generate ideas or techniques that lead to important discoveries.
New ways
Let's imagine for a moment: we are on the top floor of a skyscraper, a night city spreads out in front of us. Somewhere in the windows the light is on. Cars scurry through the streets, lighting the way with headlights, and lanterns flicker. Our brain is like a city in the dark, in which individual avenues, streets and houses are always lit.
To continue this metaphor, the brain is 'illuminated' in a variety of ways. We can "light" a huge number of "lanterns" - create neural connections, but only some of the "streets" (nerve pathways) will be illuminated throughout them. Therefore, we tend to use the same data to solve different problems, as if we were walking along illuminated streets in search of familiar information or sensations. However, there are other, unbeaten paths where unusual ideas and solutions await.
We live as if in a semi-automatic mode, solving most problems based on experience, reliable data and culture. These are three large, always lit avenues.
Remember, I said: due to entropy, the brain tries to conserve energy? He conserves strength to survive in the event of an unforeseen flight or battle. That is why, when solving an intellectual problem, we first of all turn to existing knowledge.
Our experience is a constant source of information. But if we need unhackneyed forms or ideas, if we crave inspiration or revelation, we will have to make an effort and light new “lanterns” (in other words, form new neural micronetworks). Effort requires energy. With luck, we find different answers to the same question, different solutions to the same problem. Let's call it a creative challenge.
The more precise the formulation of the creative problem, the easier it will be to find its solution. Imagine: a creative task is a drawing on a box, without which it is difficult to assemble a puzzleWhich way to work, school, university or somewhere else that we have to go every day do we choose? Always, or almost always, unchanged. The same avenue, the same streets, the same metro or bus. I would venture to suggest that we can change our morning route a maximum of two, three, four times. Why walk down a different street or take a different bus if we're sure ( knowledge ) that our usual path will lead us to the goal ( culture and experience )? The brain does not want to make extra efforts and waste energy on what is already established. Time passes, experience accumulates, and models and structures of thinking are formed in neural networks - illuminated avenues of a big city. As we shall see later, the creative process will destroy these models and structures, opening the way for what does not fit in them.
