Identifying barriers and obstacles clients face and helping remove them is part of the definition of:

The concept of advocacy in rehabilitation counseling encompasses identifying barriers and obstacles that clients encounter in their journey toward achieving their goals. Advocates work to ensure that clients' voices are heard and their needs are met by promoting their rights and facilitating access to resources and services. This role involves addressing systemic issues, such as discrimination or insufficient resources, that may hinder a client's progress.

When advocates identify specific obstacles that clients face—be it related to physical accessibility, social stigma, or lack of support systems—they actively work to remove these barriers. This could involve collaborating with employers, educators, and service providers to create more inclusive environments or helping clients navigate institutional policies that may pose challenges.

The other options do not encapsulate the same focus on removing barriers. Support services refer to the additional resources provided to clients, while referral pertains to directing clients to appropriate services or professionals. Assessment involves evaluating a client's needs and abilities but does not directly involve the advocacy role of addressing and removing barriers.
