Which of the following is a major impairment category?

• A. Visual impairments
• B. Hearing impairments
• C. Knowledge deficiencies
• D. Skill deficiencies

Answer: (D)

Understanding impairment categories in this context means looking at what most directly hinders actually doing the required tasks. While having good vision and hearing is essential, and gaps in knowledge can be filled with study, the ability to perform the tasks themselves hinges on skill. Skill deficiencies show up when someone can understand the material but cannot consistently execute the procedures, techniques, or behaviors the job requires. That direct impact on performance is why skill deficiencies are considered the major impairment category: they block practical, real-world capability and demand focused practice and mastery.
