Which of the following is NOT a class of impairment?

The classification of impairment typically includes profound, severe, and mild categories. These terms are commonly used in various contexts to describe the extent of a disability or impairment in individuals, particularly in fields like special education, health care, and social services. Profound refers to a significant level of impairment, which severely limits an individual's daily functioning. Severe also denotes a high level of impairment but may allow for some minimal functioning in specific areas. Mild impairment indicates a lesser degree of disability, often allowing individuals to engage more fully with their environment.

Transitional, on the other hand, does not fit into the standard classifications of impairment. It is often used in a different context, such as in transitional services or programs designed to assist individuals in shifting from one context of support to another. It does not directly describe a level of impairment like the other three terms, which focus on the severity and impact of a disability. This distinction clarifies why transitional is the correct answer to the question, as it does not align with the established classes of impairment.
