The 1991 ADA requires what specific type of accommodations?

The Americans with Disabilities Act (ADA), enacted in 1990 and effective from 1991, mandates that public and private entities provide reasonable accommodations to employees with disabilities. This means that employers are required to make modifications or adjustments to the work environment or the way things are usually done, to ensure that individuals with disabilities have equal opportunities in the workplace. This requirement is designed to support the rights of individuals with disabilities and facilitate their ability to perform their job duties effectively.

In contrast, mandatory ASL classes for all staff, fixed roles for interpreters, and immediate intervention in all cases do not reflect the spirit or the letter of the ADA. The focus of the ADA is on ensuring accessibility and reasonable accommodation rather than establishing a specific set of training programs or rigid roles for interpreters. Thus, the emphasis on reasonable accommodations for employment aligns directly with the core principles of the ADA, making it the correct answer.
