Reading comprehension is the ability to read a text, understand what it means and connect it to what you already know. It is the goal of reading. A student with good comprehension can explain the main idea, recall important details, make inferences about things the author did not say directly and use the information to answer questions or learn something new. In short, the comprehension meaning is "understanding": decoding turns print into words, and comprehension turns those words into meaning.
What does comprehension mean?
If you look up how dictionaries define comprehension, you will find something like "the act or ability to understand." In reading, comprehension is an active process. The reader builds a mental model of the text while reading: who is involved, what is happening, why it matters and how the ideas connect. Good readers constantly check that model, notice when something does not make sense and fix the problem, for example by rereading. This habit of thinking about your own thinking is called metacognition.
Comprehension happens at different levels:
- Literal comprehension: understanding facts stated directly in the text (who, what, where, when).
- Inferential comprehension: reading between the lines, drawing conclusions, predicting and understanding cause and effect or a character's feelings.
- Evaluative (critical) comprehension: judging the text, comparing it with other texts, recognizing the author's purpose and forming an opinion. This level draws on critical thinking skills.
The Simple View of Reading and the Reading Rope
The Simple View of Reading, proposed by Philip Gough and William Tunmer in 1986, says that reading comprehension is the product of two abilities: word recognition (decoding) and language comprehension (understanding spoken language). Because the two are multiplied, not added, a weakness in either one lowers reading comprehension. A student who understands stories read aloud but cannot decode will struggle, and so will a student who decodes well but has limited vocabulary or language skills.
Scarborough's Reading Rope, created by psychologist Hollis Scarborough, shows the same idea as a rope made of many strands. The lower strands are word recognition skills: phonological awareness, decoding and sight recognition. They become more automatic over time. The upper strands are language comprehension skills: background knowledge, vocabulary, language structures (grammar and syntax), verbal reasoning and literacy knowledge (such as knowing genres and print concepts). They become more strategic over time. Skilled reading happens when all strands are woven tightly together.
Skills that reading comprehension depends on
Decoding and fluency
Students must be able to read the words. Solid phonics knowledge, accurate decoding and good reading fluency free up attention and working memory for understanding. When a student reads slowly and makes many errors, meaning gets lost.
Vocabulary
Readers need to know the meaning of most words in a text to understand it. Good readers also use context clues to infer the meaning of unfamiliar words and phrases. Vocabulary grows through conversation, being read to, wide reading and direct teaching of important words, including academic words like analyze or compare.
Background knowledge
What a student already knows about a topic has a big effect on comprehension. A student who knows about baseball will understand a baseball story more easily than a student with the same reading level who has never seen a game. Building knowledge in science, social studies and the arts supports reading.
Language and executive skills
Understanding complex sentences, pronouns and connecting words such as however or because is part of language comprehension. Executive functioning skills, such as attention, planning and self-monitoring, help students stay focused and notice when they have lost track of meaning.
Reading comprehension strategies
Comprehension strategies are deliberate actions readers use to understand and remember text. They turn passive reading into active reading. The National Reading Panel found that teaching students to use several strategies helps them understand more. Strategies work best with a gradual release of responsibility: the teacher explains and models a strategy, practices it with students and then hands it over so students use it on their own. Before reading, it also helps to set a clear purpose for reading, such as finding out how something works or why a character made a choice.
- Activating prior knowledge and predicting: before reading, students think about what they know and what the text might be about.
- Questioning: students ask and answer questions during and after reading, from literal "who" questions to "why" and "what if" questions.
- Visualizing: students create mental images of what is described, which helps with memory and inference.
- Monitoring and clarifying: students stop when something is confusing and use fix-up strategies such as rereading, reading ahead or looking up a word.
- Summarizing: students identify the main idea and the most important details and restate them in their own words.
- Using text structure: students recognize how the author organized the text, such as sequence, cause and effect or compare and contrast. See text structure.
- Using graphic organizers: story maps, Venn diagrams and flow charts help students organize information visually. See graphic organizer.
Structured approaches such as a technique called reciprocal teaching combine several of these strategies (predicting, questioning, clarifying and summarizing) in small-group discussion.
Signs of reading difficulties in comprehension
A student may have trouble with comprehension if they:
- Can read a passage aloud but cannot retell it or answer questions about it.
- Remember isolated details but miss the main idea.
- Have difficulty making inferences or understanding figurative language.
- Do much better when text is read aloud to them, which suggests a decoding problem, or do poorly even when it is read aloud, which suggests a language comprehension problem.
- Avoid reading, take a long time on reading assignments or get lower grades in subjects with heavy reading.
Comprehension difficulties can be linked to dyslexia, language disorders such as expressive language disorder, ADHD or limited vocabulary and background knowledge. Some students have what researchers call a specific reading comprehension deficit: they decode well but still struggle to understand.
Support and accommodations
Schools often address comprehension first through classroom instruction and tiered support within MTSS. If a disability is suspected, the school must evaluate the student. Under IDEA, reading comprehension is one of the eight areas in which a specific learning disability can be identified (34 CFR 300.309), alongside basic reading skills and reading fluency skills.
To improve reading comprehension, the first step is finding out which part of reading is weak: decoding, fluency, vocabulary, background knowledge or strategy use. Instruction should then target that area. Helpful supports include explicit strategy instruction, pre-teaching vocabulary, graphic organizers, text-to-speech and audiobooks through assistive technology, highlighted or chunked texts, guiding questions before reading and extended time. See accommodations vs. modifications for how these differ.
Reading comprehension goals in the IEP
An IEP goal for comprehension should be based on the student's present levels and be measurable. For example: "Given a grade-level informational passage read aloud or with text-to-speech, the student will identify the main idea and three supporting details with 80% accuracy in four out of five trials, as measured by teacher-made probes." Other goals may target answering inferential questions, retelling a story in sequence or summarizing a paragraph. Goals should name the skill, the conditions, the level of the text and how progress will be measured.
Frequently asked questions about reading comprehension
What are the 5 reading comprehension skills and strategies?
Lists vary, but five commonly taught strategies are predicting, questioning, visualizing, monitoring (clarifying) and summarizing. Many teachers also teach making connections, inferring and using text structure.
Why is reading comprehension important?
Reading comprehension is how students learn from text in every subject. Without it, reading becomes word calling. Comprehension also matters for following directions, taking tests and everyday tasks outside school.
Is poor reading comprehension a sign of ADHD?
Not by itself. Many students with ADHD have trouble with comprehension because attention and working memory affect how well they follow and remember text, but comprehension problems have many possible causes. An evaluation looks at all of them.
How can I improve my child's reading comprehension at home?
Read together and talk about the text: ask what happened, why it happened and what might come next. Explain new words, connect books to your child's experiences and encourage reading about topics your child enjoys to build knowledge.
Can a child read well but not understand?
Yes. Some children decode and read aloud fluently but have weak vocabulary, background knowledge or language skills. An evaluation can show which parts of reading need support.
