What Is Inference
Inference is the process of combining information directly stated in a text with what a reader already knows to reach a conclusion that isn't explicitly written. When a child reads "Maya grabbed her umbrella and ran outside," inference lets them understand it's probably raining, even though the text never states that fact.
This skill sits at the foundation of reading comprehension. Without inference, readers stay locked into surface-level meaning. With it, they understand plot, character motivation, and deeper layers of text that strengthen comprehension across all grade levels.
Why It Matters for Struggling Readers
Struggling readers often focus so much on decoding individual words that they miss inference opportunities entirely. Research shows that students who can't make basic inferences score significantly lower on standardized reading assessments. In fact, inference questions make up roughly 50-60% of comprehension assessments by grade 4.
For readers with dyslexia or processing delays, inference is particularly challenging because the cognitive load of decoding consumes working memory that inference requires. An Orton-Gillingham intervention emphasizes phonetic decoding accuracy as a foundation, which reduces cognitive burden and frees mental resources for inference and higher-order thinking. When IEPs address inference explicitly, they often specify whether the barrier is decoding fluency, prior knowledge gaps, or the inference process itself.
How to Teach Inference
- Start with explicit modeling: Read a passage aloud, pause mid-story, and voice your thinking: "The character is shivering. I know shivering happens when it's cold. So I infer it's a cold day." Make invisible thinking visible.
- Build background knowledge first: Prior knowledge fuels inference. Struggling readers need pre-reading activities that activate or build background knowledge before tackling inference-heavy texts.
- Anchor inferences to text evidence: Every inference must point back to specific words or details. "I inferred the character was angry because he slammed the door" beats "He seemed mad." This trains readers to ground inferences in text evidence.
- Practice with accessible texts first: Don't pair weak inference skills with advanced reading levels. Use high-interest, lower reading-level texts so students can focus on the inference process, not decoding.
- Scaffold gradually: Move from "What does the text tell us?" to "What can we figure out that the text doesn't say?" to independent inference work.
Inference and IEPs
When inference appears in an IEP goal, it typically falls under inferential comprehension standards. A well-written goal might read: "By [date], the student will identify two supporting details from a grade-level text and use them to make one inference about character motivation with 80% accuracy across three consecutive sessions." This ties inference to measurable progress and specific text types.
Common Questions
- Can inference be taught, or is it just a natural reading skill? It can absolutely be taught, especially with explicit, structured instruction. Students with dyslexia, ADHD, or language processing delays benefit from direct teaching rather than the discovery-based approaches that work for stronger readers.
- How do I know if a child's inference struggles come from decoding problems or actual inference difficulty? Use an easier text where decoding isn't a barrier. If the student can then make inferences, the problem was decoding load. If they still struggle, the inference process itself needs targeted work.
- What's the difference between inference and prediction? Inference looks backward or sideways at what we already know. Prediction looks forward at what will happen next. Both require combining text clues with prior knowledge, but they serve different comprehension purposes.
