Competence and access are different
A child may demonstrate a skill in one setting and appear unable to use it somewhere else. That difference does not automatically mean refusal, loss of learning, or lack of motivation. The skill may be present while access to it is temporarily reduced.
Consider what the task requires at that moment: listening, understanding language, planning movements, tolerating sensations, shifting attention, remembering steps, communicating uncertainty, and recovering from earlier demands. Each requirement draws on available capacity.
NICE guidance recommends assessing communication, physical health, mental health, the sensory and social environment, changes in routine, and predictability when behavior becomes difficult to manage.
The capacity equation
Capacity is dynamic. It reflects the interaction between what is available inside the person, what the environment is asking, and what support is present.
Available resources
Sleep, nourishment, physical comfort, emotional safety, communication access, attention, motor control, and recovery from previous demands.
Current demands
Task length, number of steps, language load, sensory intensity, social expectations, transitions, speed, novelty, and uncertainty.
Available supports
Visual information, AAC, modeling, extra time, environmental adjustments, reduced steps, choice, breaks, and trusted co-regulation.
Accessible performance
What the child can initiate, communicate, complete, tolerate, or recover from under those particular conditions.
Signs that capacity may be exceeded
These signs are nonspecific. They identify a need to observe and adjust; they do not diagnose a medical, sensory, or behavioral condition.
- A familiar task suddenly requires substantially more prompting or assistance.
- Speech, AAC use, motor precision, flexibility, or response speed decreases.
- The child completes the skill in one environment but not in another.
- Participation drops after poor sleep, illness, pain, long periods of demand, or sensory exposure.
- Distress rises as language, correction, speed, or repeated prompting increases.
A better response when performance drops
- Describe the exact point where access changed instead of labeling the whole task a failure.
- Check pain, illness, sleep, hunger, hydration, medication changes, and other physical factors when relevant.
- Reduce one variable: fewer steps, less language, slower pace, lower sensory load, or more recovery time.
- Add one support the child understands, such as a visual, model, AAC option, choice, or partial assistance.
- Measure communication, initiation, participation, accuracy, assistance, and recovery—not quietness alone.
When to seek professional help
Arrange a professional review when access to several established skills changes, the change is sudden or persistent, or it occurs with pain, sleep disruption, gastrointestinal symptoms, weakness, frequent falls, seizures, weight change, major anxiety, or loss of previously acquired abilities.
