On what basis does vocational rehabilitation provide funding for AAC devices?

Vocational rehabilitation provides funding for AAC devices primarily based on the potential for higher education and employment. This approach recognizes that the primary goal of vocational rehabilitation is to assist individuals with disabilities in obtaining and maintaining employment, which directly impacts their quality of life and independence. By assessing a person's potential for higher education and their ability to secure meaningful employment, vocational rehabilitation can identify the specific support, such as AAC devices, that will be most effective in enabling individuals to effectively communicate in a work setting.

Funding decisions focus on enhancing a person's capabilities to function in a professional environment, rather than factors like academic improvement, severity of disability, or parental income levels. While these elements may play a role in a broader assessment of an individual’s situation, the primary emphasis is on maximizing the individual's potential in the workforce, making option B the correct choice.
