Which intervention technique is explicitly NOT permitted for a speech-language pathology assistant?

The correct answer is the intervention technique that is explicitly NOT permitted for a speech-language pathology assistant, which is performing invasive procedures. In the practice of speech-language pathology, assistant practitioners do not possess the qualifications or autonomy to perform invasive procedures, as these actions require specific licenses and extensive training that typically fall within the scope of a licensed speech-language pathologist. Invasive procedures could include any form of intervention that penetrates the body or involves a medical aspect outside the realm of speech and language disorders.

In contrast, tasks such as demonstrating techniques and assisting during therapy are permissible as they align with the support role of a speech-language pathology assistant, under the supervision of a licensed speech-language pathologist. Recording session notes is also allowed, as it is an integral part of documenting client progress and session details, which is essential for continuity of care. These activities can all be performed by an assistant as they do not involve the risks and responsibilities associated with invasive procedures.
