Which term best describes a change that helps improve access for individuals with impairments?

The term that best describes a change that helps improve access for individuals with impairments is "accommodation." This term specifically refers to modifications or adjustments made in order to facilitate equal access and opportunities for individuals with disabilities. Accommodations can include a wide range of changes, such as altering physical spaces to allow wheelchair access, providing special equipment, or offering additional assistance during activities. By focusing on the needs of individuals with impairments, accommodations play an essential role in ensuring their full participation in society.

The other terms, while related, do not capture this specific intent as directly. "Facility" typically refers to a building or physical space rather than the changes needed for accessibility. "Modification" and "adjustment" are broader terms that can apply in various contexts—the former often implies altering existing structures or practices, whereas the latter usually refers to minor changes or tweaks rather than specific provisions for accessibility needs. Therefore, "accommodation" is the most precise term in this context.
