Which concept best supports the idea that people with disabilities do not follow the same growth path?

• A. Universal developmental curve
• B. Development stops after adolescence
• C. Individual variability in development.
• D. Growth is solely determined by therapy intensity

Answer: (C)

Development does not follow a single, one-size-fits-all path. People with disabilities show a wide range of timing, sequences, and levels of skill across areas like communication, self-care, and social interaction. This means growth progresses differently from person to person, across life stages, and in response to supports and experiences. Recognizing individual variability helps you tailor supports, set realistic goals, and monitor progress without assuming everyone follows the same timetable or endpoint. It also fits with person-centered planning, where interventions adapt to each person’s strengths, preferences, and needs. Think of the other ideas this way: a universal developmental curve would imply everyone reaches milestones in the same order and on the same schedule, which isn’t supported by how development actually varies. Saying growth stops after adolescence ignores ongoing learning and development that can occur into adulthood. And attributing growth solely to therapy intensity overlooks the many factors at work—environment, opportunities, motivation, health, and the quality of supports influence progress as much as, or more than, sheer practice time.
