Oral comprehension: evaluating and improving language understanding
Oral comprehension is often the "poor relation" of language assessment: less visible than expression, yet it is fundamental. A child who doesn't understand well will have difficulties in all areas of learning. This guide details the different levels of comprehension, signs of difficulties, and effective intervention strategies.

Levels of comprehension
Oral comprehension is not a unitary skill but a set of hierarchical processes. Difficulties can appear at different levels, with different implications for intervention.
Level 1: Lexical comprehension (words)
This is the most basic level: understanding isolated words. Can the child point to an image corresponding to the word heard? Do they know basic vocabulary? A deficit at this level compromises all subsequent levels.
Examples of difficulties: doesn't recognize named objects, poor vocabulary, confuses similar words.
Level 2: Morphosyntactic comprehension (sentences)
Understanding the structure of sentences: word order, grammatical inflections, function words (articles, prepositions, pronouns). A sentence is not just a sequence of words but an organized structure.
Examples of difficulties: confuses "the cat chases the dog" and "the dog chases the cat", doesn't understand passive sentences, relatives, complex negations.
Level 3: Textual comprehension (texts/narratives)
Understanding a text or narrative as a whole: following the sequence of events, identifying characters and their relationships, understanding cause and effect relationships.
Examples of difficulties: loses track of the story, cannot summarize, confuses characters, doesn't understand why events occur.
Level 4: Inferential comprehension (implicit meaning)
Understanding what is not explicitly stated but must be deduced from context and general knowledge. This is the most elaborate level of comprehension.
Examples of difficulties: takes everything literally, doesn't understand humor or irony, doesn't make logical deductions.
Development of comprehension
Comprehension develops before expression: a child always understands more than they can say. Here are the major stages:
| Age | Comprehension skills |
|---|---|
| 8-12 months | Understands "no", their name, some familiar words in context |
| 12-18 months | Understands 50-100 words, simple instructions ("give to daddy") |
| 18-24 months | Understands 200-300 words, two-part instructions, simple questions (where, what) |
| 2-3 years | Understands complex sentences, spatial concepts (on, under), "who" questions |
| 3-4 years | Understands simple narratives, "why" and "how" questions, negations |
| 4-5 years | Understands longer stories, multiple instructions, simple humor |
| 5-6 years | Understands simple implicit meaning, common figurative expressions |
Signs of comprehension difficulties
🔍 Comprehension difficulties are often masked
A child who doesn't understand well may compensate by relying on context, imitating others, or giving vague responses. Difficulties can go unnoticed until demands increase. Watch for the following signs:
At home
- Doesn't respond correctly to questions
- Responds "yes" or "no" without the answer being coherent
- Seems "in their own world" or not listening
- Needs things repeated often
- Executes instructions incompletely or incorrectly
- Watches what others do before acting
- Responds off-topic
- Better with gestures or visual supports
At school
- Doesn't follow group instructions
- Difficulty answering comprehension questions
- Gets lost in texts, cannot summarize
- Difficulty with math problems (understanding statements)
- Zones out during long oral explanations
Causes of comprehension disorders
Comprehension difficulties can have several origins, sometimes combined:
| Cause | Characteristics |
|---|---|
| Developmental Language Disorder (DLD) | Difficulties affecting the receptive aspect of language, often with expression also affected |
| Vocabulary deficit | Insufficient lexical stock: the child doesn't know enough words |
| Attention deficit | The child didn't "catch" the information because their attention was elsewhere |
| Working memory deficit | Information is lost before being processed, especially for long statements |
| Hearing disorder | Information doesn't arrive correctly (deafness, auditory processing disorders) |
| Intellectual disability | Comprehension difficulties as part of global delay |
| ASD | Specific difficulties with implicit meaning, figurative language, social context |
Assessment of comprehension
Comprehension assessment is carried out by a speech-language pathologist as part of a language evaluation. It explores different levels:
- Lexical comprehension: picture pointing, word definition
- Morphosyntactic comprehension: instruction execution, sentence pointing
- Narrative comprehension: story listening and questions
- Inferential comprehension: deductions, implicit meaning
Standardized tests (EVALO, ELO, ECOSSE, etc.) allow positioning the child relative to age norms and identifying deficit levels.
Strategies to improve comprehension
📝 Simplify the message
Use short sentences, known vocabulary, give one piece of information at a time. Avoid complex structures (passives, embedded relatives). Get to the point.
🖼️ Illustrate and contextualize
Accompany words with gestures, images, demonstrations. Visual context helps understand the verbal message. Use visual supports whenever possible.
✅ Check understanding
Don't settle for a "yes" from the child. Have them rephrase in their own words, ask verification questions, observe if the action matches the instruction.
🔄 Repeat and rephrase
Say it differently, use synonyms, repeat the information in a different form. Repeated information is more likely to be encoded.
🎯 Get attention before speaking
Make sure the child is available and attentive before giving important information. Call their name, establish eye contact, reduce distractions.
📚 Enrich vocabulary
A child understands better if they know the words used. Regularly expose to new vocabulary in varied contexts, explain unknown words, use picture books.
Adaptations for the environment
For parents
- Speak facing the child so they can see your face
- Give instructions one at a time rather than in series
- Use visual cues for routines
- Read stories regularly while asking simple questions
- Avoid talking while the TV or other noise is on
For teachers
- Strategic placement: near the teacher, facing the board
- Written instructions to complement oral ones
- Rephrase instructions individually if necessary
- Check understanding before the child starts
- Allow asking for help without stigmatization

These two disorders can look similar (the child doesn't follow instructions, seems "elsewhere"). To distinguish them: an inattentive child understands when they are truly attentive (in one-on-one situations, without distractors). A child with comprehension disorder has difficulties even in optimal attention conditions. Often, both coexist.
At home, the child benefits from numerous contextual aids: known routines, gestures, familiar context, individual attention. At school, they must understand group instructions, in a noisy environment, with fewer visual supports. A mild comprehension disorder may be compensated at home but revealed at school.
Yes, with appropriate intervention. The speech-language pathologist works on deficit levels (vocabulary, syntax, inferences). The environment can be adapted to facilitate comprehension. However, a severe comprehension disorder can have lasting repercussions and require long-term adaptations.
Consult a speech-language pathologist if your child has persistent comprehension difficulties that impact their daily life or learning. Don't wait: the earlier the intervention, the better the results. The doctor or teacher can refer you for a speech-language assessment.
