Accessibility Of Higher Education: Supporting Student Self-Advocacy, Morgan Diane Halliday

Occupational Therapy Capstones

As of the 2020-2021 academic year, 1 in 5 undergraduate students reported having a disability (National Center for Education Statistics, n.d.). College students with disabilities (CSWD) face social and physical environmental barriers to higher education due to exclusive policies, procedures, and designs. In turn, occupational engagement is decreased, inhibiting participation in education. A college education can support career opportunities, financial stability, and personal development (Plotner & May, 2019). Therefore, it is essential that CSWD have equitable access. Despite efforts from college campuses to become more accessible, gaps remain that require CSWD to be self-advocates. The purpose of this project was …
