Which of the following is NOT a task an assistant can do regarding patient records?

Conducting patient evaluations is a task that requires a higher level of expertise and clinical judgment, which is typically reserved for licensed speech-language pathologists. Assistants play an important role in supporting services but are not qualified to perform evaluations that determine a patient's diagnosis or eligibility for treatment.

In contrast, documenting historical information in sequence, compiling session to session data, and obtaining records from external agencies are all administrative or supportive tasks that assistants can perform. These activities help maintain accurate records and ensure continuity of care, but they do not involve the clinical decision-making processes required in evaluations.

By keeping this distinction in mind, it's clear that conducting patient evaluations goes beyond the scope of an assistant's responsibilities, highlighting the unique role that licensed professionals play in the assessment and treatment processes.
