Which of the following phrases would be most appropriate when describing students who have a disability or injury?

Choosing the phrase "the student is a person with Down Syndrome" is appropriate because it emphasizes the person-first language approach, which is respectful and acknowledges the individual before their disability. This type of language promotes dignity and recognizes that a person's condition does not define their entire identity.

In this context, describing someone as a "person with" a specific condition helps to maintain their humanity and individuality. It reflects a modern understanding of disabilities, focusing on the person rather than the disability itself. This approach is consistent with current best practices in advocacy and education for individuals with disabilities, which aim to foster inclusivity and respect.

The other phrases may carry negative connotations and focus on the disability in ways that can be seen as stigmatizing. They emphasize the condition instead of the person, which does not align with the inclusive values promoted in contemporary discourse regarding disabilities.
